It’s Complicated

When people first hear me say that I am blind or severely visually impaired (B/VI), the most common reaction is surprise…followed by sympathy…followed most often by awkward silence. This is totally understandable. Unless you are regularly interacting with differently abled people, disabilities are uncomfortable. I feel uncomfortable and awkward around people who live with other forms of disability.

Heck, I’m still awkward around other people who are B/VI. And even this is understandable. Because each person is unique. Each manifestation of visual impairment is unique. Each path to and with B/VI is unique. Each person has unique life experiences, coping mechanisms, support networks, etc. We are all strangers in a strange land. I’ll have other posts dedicated to the whack-a-doo personal and social psychology of B/VI. For now, the focus remains on the physical, or rather the perceptual.

The second reaction is usually a question: “How bad is it” or “What do you see?” And my answer is “It’s complicated.”

In my first post, I laid out some more technical details: I have a visual field that is less that 10 degrees, night blindness, color blindness, uncorrectable myopia, light sensitivity, etc. But it’s not apparent how these details really affect what I see and how that impacts what I can do. This post will go into greater detail into what and how I see. Later posts will focus on how I (try to, with varying levels of success, stupidity, and hilarity) cope with these limitations.

It probably makes sense to start with my visual field, as this is the aspect of my vision that “qualifies” me as legally blind. However, before getting to that, we really need a basic understanding of how humans see. Don’t worry, I’ll keep it short and simple.

It may be easiest to compare the eye to a modern digital camera. A camera lens gathers and focuses light; it also constrains the amount of light passing through by altering the size of a mechanical aperture. In the human eye, these functions are performed by the lens and the pupil, respectively. In a digital camera, the lens focus light onto a CCD or CMOS sensor, which is a dense grid of light sensitive “pixels,” each generating a small electrical charge proportional to how much light (within a certain wavelength) is hitting it. The human retina is the biological, electrochemical equivalent. Finally, a digital camera has wires that transport these electrical signals to a computer, which then interprets the signals to create a digital image. Here, the human analogues are the optic nerve and the visual cortex within the brain.

As I noted in my first post, I have Retinitis Pigmentosa (RP), which primarily impacts my retina. Due to the wonders of genetics and epigenetics, other parts are impacted. But for now, I’ll focus on the retina. Characteristically, people with RP find that their retinal “pixels”—millions of light-sensitive “rod” and “cone” structures, as well as protective retinal pigment epithelial (RPE) cells from which the disease gets its name—stop functioning from the outside in. We don’t know the exact cause, nor is there yet any proven way to slow, much less reverse the process.

Of course, this is a biological process that is unique to each individual. For me, it has progressed relatively slowly from childhood. I can recall early symptoms as far back as age 6. I’ll have a separate post at some point talking about progression. But it is notable the process is neither steady nor predictable. I’ll have periods of relative stability followed by periods of perceptible loss. It’s rarely like a light switch, but rather more like a dimmer. Each area of loss will appear darker with less usable information until it is just “clicked off” by the brain, presumably redirecting its limited processing resources to doing something other than trying to interpret shotty data from dying cells. For me, the progression has also been very spotty—for example, I retained some usable vision in the extremes of my left-right periphery until just a couple years ago, despite progressively losing most of my peripheral vision between there and my center.

The result today is that I have very little of my retina remaining that pretends to function “normally.” I can detect very high contrast light vs. dark in some of my periphery, but nothing there that you would qualify as usable sight. My central vision is still somewhat functional, but has been fading rapidly of late. As I said, it’s spotty, but on average in good light I have maybe 10-15 degrees total horizontal vision and less than 10 vertical. And much of that is probably equivalent to what most would consider to be peripheral vision. To help better “feel” what this means, here are a few examples of how this manifests itself in my day-to-day life.

When I’m sitting across a table from you, I can see your face but not your hands. If I’m not socially distant, I might be able to see your eyes or your mouth, but not both at the same time. I often creep people out during a conversation because I’m constantly losing eye contact and moving my eyes to different parts of their body. I promise, I’m not “undressing you with my eyes”—people talk with their entire bodies, and I’m simply trying to catch as many visual cues as possible.

When watching TV from 10 feet away, I can “see” my entire 55-inch screen. But less than a quarter of that is in my central vision. I have to move my eyes to see detail or read signs or captions. Sports and fast action scenes are difficult to catch. A fast action, dark scene with subtitles…oy…the Battle of Winterfell may as well have been a BBC Radio broadcast.

I can read, though usually only slowly and for short periods, especially if it is paper and ink. I see only a few words at a time, so my eyes have to constantly move. This causes a lot of eye strain, and I have trouble keeping both eyes properly oriented and occasionally have periods where one eye twitches uncontrollably—obviously I’m channeling my inner Mad-Eye Moody.

And of course, navigating unfamiliar or unpredictable environments is very difficult. I navigate by moving from waypoint to waypoint, and if I don’t know the waypoints or if things jump in my way, well, bad things happen. Or maybe funny things.

More on all of these and their many repercussions in future posts.

People ask, “What do you ‘see’ in the places where you have no vision? Is it blackness? Emptiness? Blurry?” Again, it’s complicated, but for the most part, my brain has just removed those areas from its visual processing “algorithm.” So, I see the same thing that you see when something is beyond your peripheral vision…just nothing. There are long periods of adjustment as I lose sight—kind of like losing a limb and still expecting it to be there. But eventually it’s just not a part of the picture that my brain paints of the world around me.

Unfortunately, that’s not all. Night blindness is often the first detected symptom for folks with RP. What is left of my retina doesn’t detect light well, so I need much more of it. The result is that I’m totally blind in low-light situations. I need direct light to see any kind of detail. I carry a flashlight everywhere I go and use it regularly day and night.

So, I need bright light. But it is also my nemesis. My eyes compensate like one would with a digital camera…by cranking open the aperture (pupil) and turning up the gain on the sensor. This does allow me to function semi-normally in certain situations. But it also results in severe light sensitivity. As with a camera, the wider pupil also results in loss of detail, and bright light can almost entirely wash any other visual information. To make matters even worse, although my pupils do function, they are VERY slow to adjust.

The results of all of that are varied. I’ll post more details in the future. But for example, I am no longer able to read a computer screen for any length of time without inverted colors. It’s like trying to read while staring at headlights. I truly need dark mode on all of my devices. Also, changing lighting conditions are challenging, especially when they are extreme. When I come in from outside, my eyes can take many minutes to adjust. And bright light sources like sunny windows in otherwise moderately lit environments can really cause havoc.

Finally, a common comorbidity with RP are cataracts, which cause hardening and blurring of the lens. Of course, this one hit me, as well. A number of years ago, I had cataract surgery. It was great. I was the youngest patient in the surgery center by like 30 years. The process involves using a magic wand to dissolve your natural lens and replacing it with a plastic one. This gets rid of the blurring, but entirely removes the ability to focus. As a bonus, I did go from needing coke bottle glasses to just needing a couple of diopters of correction. But this further complicates reading, and means I’m constantly donning and doffing my specs or having to look below them to read. Minor in the big scheme of things, but it does make me look and feel like a damn old fart.

Okay, if you made it this far, you deserve to be let off the hook for now. There’s more like the fact that my corneas—the eyes’ (usually) clear “lens caps”—now seem to cause my sight to remain blurry for the first couple of hours of each day. Or that the eye strain can sometimes get so physically painful that I have to close my eyes for long periods during the day. But this is a mostly complete and accurate snapshot of what I’m currently living with physically.

I guess I didn’t present too many funny or uplifting or forward-looking things in here. Truth is, you kind of have to muddle along with me through these sewers to eventually find the humor and hope in all of this. Because it’s complicated. But I’ll get there if you’re patient.

How to Calibrate an Optical Sight

Recently, many newbies have poured into the scope of sights, and after careful selection, they have chosen their own precious sights, but on the issue of "how to calibrate the optical sights", they are like monks who are two feet tall and can't figure it out. ! Let's briefly talk about "how to calibrate the optical sight"!

The sight usually has two lenses, one close to the eye is called the eyepiece, and the other is called the crop mirror. The zoom sight is usually marked with a scale on the lens of the eyepiece. Take 354124B as an example, its magnification is 4-12 , then the scales marked on it are the numbers of 4, 5, 6, 7, 8, 9, 10, 11, 12 multiples.

The first is to rotate the knob on the eyepiece to adjust the diopter. Objects at different distances will appear blurry at some magnifications, so there is no specific magnification to make the fixed target clear, including the human eye. There will be differences in the recognition of things, so different distances should be adjusted continuously until the adjustment is very clear, which is the most suitable magnification for the target you observe.

In fact, such diopter adjustment and focusing are very easy to understand. As long as you keep adjusting to a clear picture, you will be successful. The focus is on the deviation and height adjustment buttons above and next to the fuselage. The distance compensation knob is located at the top, which is located on the side of the fuselage. The one is the wind deflection knob, these are more professional words.

In fact, it is the adjustment of the up, down, left, and right of the impact point through the adjustment of the scope, because the trajectory of the shooting object flying in the air is not a straight line. Due to the effect of gravity, the object will gradually drop or change its trajectory. Therefore, it must be adjusted through the up, down, left and right function keys to ensure that it can be very close to the center point in the scope, and has achieved accurate aiming.

When adjusting the impact point, you first need to determine a distance, usually from far to near, for example, you are 20 meters at the beginning, and then change to 15 meters after calibration.

The knob that adjusts the impact point is usually covered with a cover, and it doesn’t matter if some have it. Each product has a different design. There is an arrow on the upper knob marked “UP”. Everyone understands the meaning of UP. Generally, it is rotated in the direction of the arrow. Generally, the upper and lower impact points are adjusted, and then the shooting correction is performed, such as 3 rounds and 5 rounds. If the shooting results are all below the cross line, you can rotate in the UP direction. After continuous adjustment, the impact point of shooting again will gradually match the cross. The horizontal lines in the center of the line overlap. If the shooting result is below the cross line, just rotate in the opposite direction of UP.

Since the knob marked UP above is for up and down adjustment, the knob on the side of the fuselage represents left and right adjustment, and is usually marked with an English L. Similarly, open the cover and rotate in the direction marked by the arrow, it is to Left, turn against the arrow to go right, and also shoot 3 or 5 rounds. If the impact point is on the right side of the cross center, it will rotate in the direction of L; if the impact point is on the left side of the cross center, it will rotate in the opposite direction, so The impact point will gradually move closer to the center of the vertical line of the crosshair.

As for the rotary knob, whether it's left or right or up and down, the offset for a click is a quarter of an inch, which is one division of adjustment, and for an inch to millimeter conversion, 1 inch equals 25.4 mm, so a click One offset is a 6.35mm shift from the impact point at 100 yards. For the unit of meter and yard, you can convert it by yourself according to your usage habits. 1 yard is equal to 0.9144 meters. A higher and more accurate magnification may answer one-eighth of an inch.

The calibration of each scope is basically the same, but more understanding and practice are required. If you need other suitable optical sights, you can pay attention to Zhongshan Xiangyu Precision Instrument Cable Co., Ltd., providing high-quality optical sights for sale~

Microscopic examination of the bolts where done using longitudinal and latitudinal mounts for each. The sections taken from the fractured bolt were taken close to the fracture surface. Examination before etching of the two bolts showed no cracking or unusually large inclusions.Study the fracture surface under Stereo-microscope at 60X Magnification. The original broken bolt did show some flaking at the base of the threads but this is expected for a bolt that has been in service. Etching the sections revealed a microstructure of coarse pearlite in a matrix of ferrite. The SAE grade 5 standard requires that the bolt be quenched and tempered to conform and therefore should have a tempered martensite structure. Martensite has higher material properties such as yield strength and hardness, which increases its resistance to fatigue initiation. The ferrite matrix of the original bolt has low yield strength, which in turn reduces

𝐇𝐎𝐖 𝐄𝐘𝐄 𝐏𝐑𝐄𝐒𝐂𝐑𝐈𝐏𝐓𝐈𝐎𝐍 𝐖𝐎𝐑𝐊𝐒?

An eye prescription is done to find out the strength of eyes and the measurements are expressed in the form of diopters. Various other measurements determine the strength of the necessary corrective devices too. The eye prescription is needed for getting the eye glasses or contact lenses.

𝗞𝗻𝗼𝘄𝗶𝗻𝗴 𝘁𝗵𝗲 𝘁𝗲𝗿𝗺𝘀 𝗶𝗻 𝗮𝗻 𝗘𝘆𝗲𝗴𝗹𝗮𝘀𝘀 𝗣𝗿𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻

• 𝐎.𝐃. 𝐚𝐧𝐝 𝐎.𝐒.: O.D. stands for oculus dexter and O.S. stands for oculus sinister. These abbreviations come from the Latin words which mean right eye and left eye respectively. Also, some prescriptions mightt just refer to your eyes as “right” and “left”. O.U. stands for oculus uterque, referring “both eyes.”

• 𝐒𝐩𝐡𝐞𝐫𝐞 𝐨𝐫 𝐒𝐏𝐇: This term tells whether you are nearsighted or farsighted and how much correction your eyes need. If the numbers are negative, you are nearsighted and a plus sign or no symbol before the number means you are farsighted.

• 𝐂𝐲𝐥𝐢𝐧𝐝𝐞𝐫 𝐨𝐫 𝐂𝐘𝐋: It represents astigmatism which represents degree of correction needed.

• 𝐀𝐗𝐈𝐒: Symbolized as “X” on the prescription, it represents the orientation of the astigmatism. This value could be between 0 and 180. The horizontal median of the eye is indicated by 180 and the vertical median is indicated by 90.

• 𝐀𝐃𝐃: An ADD is always a positive number and represents the additional power required for reading. This is seen in the lower section of a multifocal or progressive lens.

• 𝐏𝐑𝐈𝐒𝐌 (𝐩.𝐝.) 𝐚𝐧𝐝 𝐁𝐚𝐬𝐞: A prism diopters or “p.d.,” represents prescription for double vision or diplopia. The base section represents the direction of the prism. The values could be “up,” “down,” “in,” or “out,” depending on the direction the light needs to be refracted.

How to Care For Your Eyes - Improving Vision Naturally

People have been talking about the eyeball for centuries. Here are some common misnomers that we often hear when talking about the eye.

Antle: A muscle spasm of the eyelids is called antle eyes. This occurs when muscles contract in response to visual stimulation. This happens in response to light as well. The antle eye can last for several minutes to hours. Muscle spasm can be very bothersome to someone with a sensitive eye movement.

Chroma: This is the name for the thousands of tiny pigments located in the iris of the eye. They are responsible for color perception. Individuals who have yellow eyes have small amounts of chroma in their eyes. Humans, together with all other animals, can see all of the colors of the rainbow using the human eye.

Diaphragm: The muscle that runs from beneath the eye to the back of the head is called the diaphragm. This muscle helps to balance the pressure between the retina and lens. It also controls the movement of the eyeball and provides support for its movement. Individuals with eyes that are crossed have problems with the diaphragm relaxing, or not working properly.

Eustachian tube: This is the tube that runs from the middle section of the nose to the throat. The Eustachian tube serves to prevent the tears from draining into the throat from the eyes. These are glands used to moisten the eye tissues. As humans age, the glands sometimes lose their ability to produce mucus so the eyes become dry.

Orbicularis muscles: The muscles that attach the eyelid to the lower eyelid are called the modulus or orbicularis muscle. These muscles help to separate the eyelid from the lower lid. Individuals who have crossed eyes will have weak or spastic oculus or orbicularis muscles that pull the eyelid away from the lower lid.

Diopters: These are the muscles that pull the lens upwards out of the eye. Individuals who have crossed eyes will have weak or spastic diopters. In individuals with normal eyesight, the diopters pull the lens up so that the human eye can focus on a particular object in front of it.

Optic Nerve: The optic nerve is the largest nerve in the body. It begins in the middle section of the eye. The optic nerve goes through the middle of the cornea, the upper and lower eyelid, the ethmoid area, and the retina to the back of the head. When the nerve becomes pinched by muscle tension, the individual may experience a stinging sensation, which is known as glaucoma. A cataract may also occur which causes the eye to become extremely sensitive to light.

Lid Locks: Eye muscles can contract and relax during different activities. This makes it difficult to determine when the eyelids are closed. This can happen while reading or when blinking. When the lids are closed, the cornea does not allow light to enter. Individuals with crossed eyes may notice that their vision becomes fuzzy until the lid is opened. As mentioned before, when the lid is closed the eyes are able to focus on an object in front of them, but when the lid is open the eyes are unable to see anything.

Orbicularis muscles: These muscles are located on either side of the iris. Individuals with crossed eyes will notice that when they raise their eyelids the upper lids move inwards slightly. This muscle is responsible for keeping the upper lids in line with the rest of the face.

Herniated: If a part of the eye gets displaced, like the eyelids, then the eyeball has to push outward. This creates an optical illusion called the "horizontal field". This is what people see when looking at an object that lies in a straight line. The horizontal field creates blurred vision.

Overall, the human eye is a very complex organ that allows us to see through the colors of the world. Learning how to care for our eyes will help us see more clearly. It is important to develop good color vision and to maintain good depth perception. By practicing a variety of eye exercises we can achieve both. We can improve both visual clarity and accuracy.

BLOG POST: Madrid: Experiments in cinemascope

I took the Blackmagic Pocket Cinema Camera to Madrid for a couple of days on a short December holiday with my Dad (he makes a couple of Hitchcock Cameos!) Shooting anamorphic with a 1.5x ISCO Widescreen 2000 MC I wanted to see how wide I could get – probably the biggest limitation of scope shooting, especially on the BMPCC with its 2.88 crop.

.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

KINDA…ER…WES ANDERSON! So how does it do? The good news is the lens is sharp from wide open, corner to corner but there is some distortion – you’ll particularly see it in any shots with buildings and horizontals which are quite close – its battle of the bulge time! In fact, the look is not dissimilar to the vashimorphic40 filter effect (vashivisuals.com/vashimorphic40-free-anamorphic-effects-project/) which aims to replicate the field curvature of a 40mm Panavision Primo Anamorphic – think Wes Anderson! So I guess that’s not always a bad thing, depends what you are looking for. I guess for every optical flaw, there’s always an artistic defence!

DEPTH OF FIELD AND BOKEH The main downside with this combo is that its quite difficult to get any depth of field without diopters and moving in very close. The ISCO, while being a focus through anamorphic (and incredibly sharp), its minimum focus distance is around 4M, so with a 35mm Horizontal FOV, even wide open you are not going to get much bokeh, especially on the BMPCC / Speedbooster. As a side note, There are a couple of shots with a Helios 44-M7 in this (el Rastro Fleamarket footage) but everything else is with the Pentacon 30mm F3.5. There are a few shots with a 0.5 and 1.6 Diopter on the Pentacon, so background blur is possible, but for this trip I tried to keep the ‘fannying about’ with lenses and diopters to a minimum since i wasn’t on my own 😉

FLARES Really struggled with alignment on a few shots, very hard to get the ISCO to give any horizontal flares even pointing into the sun. This is possibly because its the MC version (Multi Coated) which will be more flare resistant.CONCLUSION For £30 i paid for the lens, I’m fairly delighted with it, especially in terms of edge to edge sharpness. You just need to be careful with the distortion on closer shots in particular if that’s not what you are looking for. But using it alongside a few other lenses, it will certainly be handy to have it there as an option.

#12 Breakdown of Diya’Al Din’s original astrolabe

After contacting Hemisferium I was surprised to learn that my object was not an exact replica of the original piece made by Diya’Al Din Muhammad in 1647, but that it had involved an extensive team who worked on analysing the original and then updating it for the contemporary day.

Object title: Astrolabe: Eastern

Maker(s): Diya' al-Din Muhammad (Maker)

Date produced: 1647 - 1648

Place of production: Lahore, Pakistan

Material(s): Brass, Copper

Dimensions (H x W x L): 21.1 (cm) x 12.3 (cm) x 4.1 (cm) (Object)

Dimension notes: Mater thickness: 0.9 cm

Description: Body, rete, graduated diopter with scales and sights, pin, handle, ring and 4 tympans. Horse missing. 33 star markers. Labelled in Arabic.

Inscription/signature: `amal diya' al-din muhammad ibn mulla qa'im muhammad ibn mulla `isa ibn mulla allahdad asturlabi humayuni lahawari sanah 1057 hijri" [The work of Diya' al-Din Muhammad ibn Mulla Qa'im Muhammad ibn Mulla `Isa ibn Mulla Allāhdād, the astrolabe-maker, the Humayuni, the resident of Lahore, in the year 1057 of the Hijra].

On display: Astronomy in Culture

Hemisferium were able to provide me with a breakdown of how exactly the original 1647 Diya’Al Din Muhammad astrolabe is composed which is as follows:

Front

Engraved on the original mater are two concentric circles, bearing names of cities, their longitudes, latitudes and identification.

The inner circle includes two cities referenced on the back of the instrument: Lahore, longitude 109° and latitude 31.5°, and Varanasi, longitude 117.2° and latitude 26.5°

On the periphery we find the limbus, or outer rim, labelled with 1 degree marks and 5° intervals which run clockwise from 1° to 360°, with the latter located under the throne.

This original piece includes four different plates for different latitudes, plus two others, one of them with multiple horizons and the other for the 66.5° latitude, which enables the user to convert from equatorial coordinates to ecliptic ones.

In the lower part of each plate there is a notch that fits onto a pin in the lower part of the mater, so that the plate is properly fixed and there are no displacements.

On the plates or tympani, circles denoting heights (almucantars or almucantarats) are indicated every 3° and azimuths every 30°.

Uneven hours and Babylonian hours are also represented.

The rete or net, which is on the surface of the mater, portrays the ecliptic, which is subdivided every 6, 12, 18, 24 and 30 degrees, starting from each sign of the zodiac. Stars are noted on a separate list, thirty-three in total.

Back

The back of the instruments is divided into upper half and lower half.

Upper half of the back

On the outer rim of the semicircle, the upper half contains two scales for measuring heights, labelled degree by degree (following the alphanumeric system) and with divisions at every 5° up to 90°, starting from the horizontal on both right and left.

Each scale originates at 0° and ends at 90° in the central section of the throne, in such a way that the left-hand side scale progresses clockwise, and the right-hand side scale goes anti-clockwise.

On the left-hand side of this semicircle there is a Sine scale divided into thirty equal double parts.

On the right-hand side there is a scale of maximum heights, which represents the curves for latitudes – 27° (Varanasi) and 32° (Lahore).

This scale for maximum heights includes distances for the entrance into the signs of the Zodiac (separated by equal distances).

There are ‘prayer lines’ with the purpose of indicating the correct times for Muslim prayers in the different seasons.

In most Islamic astrolabes, a quadrant on the back (quarter of the circle) depicts a chart corresponding to the Sun’s altitude at the moment it crosses the zenith in Mecca for a particular latitude. This way, if we determine the altitude corresponding approximately to a particular day of the year, we will see the Sun is located at the altitude we have determined on the chart. The Sun’s azimuth at that moment will correspond to the azimuth of the Qibla.

Lower half of the back

The lower half has an engraved ‘shadow quadrant’ which is an altitude scale.

On the right, both the straight shadow scale (umbra recta) and the reverse shadow scale (umbra versa) are divided into 12 inches.

On the left, they are divided into seven feet.

Inside this square are engraved the names of the signs of the Zodiac and, further inside, the Lunar Mansions.

On the rim of the lower half, surrounding the shadow quadrant, there is a cotangent scale.

The right-hand side is divided into 36 parts and the left-hand side into 21 parts.

Alidade

The alidade has sights/vanes which allow the user to establish the altitude of the Sun and the stars.

It is furnished with a scale for maximum heights and another scale for the Sine measures.

This astrolabe does not have the typical bolt which traverses the alidade, the mater, the tympanum and the rete.

Although it has an indentation which matches the wedges of the other components and allows the user to rotate the alidade and the rete over the plates

Throne or Kursi

At the top of the back, there is a detailed throne with a hole designed for the hanger rings. (So the user could hold the Astrolabe easily).

In the centre of the back is the name of Diya' al-Din Muhammad, that he was the son of Qa'im Muhammad, and that is was produced in Lahore in 1647-48.

What is Notably missing

Hemisferium noted an important shortcoming in the original astrolabe is that there is no regula, and the hours are not inscribed on the limbus in two XII-hour halves; there is no zodiacal calendar either.

Fujifilm’s “affordable medium format” GFX 50R announced, along with development of 100MP GFX 100S

After plenty of rumors about the affordable and compact Fujifilm GFX 50R and the 100MP GFX 100S, now it’s official: Fujifilm has launched the GFX 50R for preorders and announced the development of the GFX 100S. The GFX 50R retails for $4,500, which isn’t exactly a pocket change, but it’s still $1,350 cheaper than the Fujifilm GFX 50S.

Fujifilm GFX 50R

A photo and sketches of the Fujifilm GFX 50R leaked a few weeks ago, but didn’t reveal much about the camera. There was some information we could have concluded from the rumors though, such as the 2-way tilting screen, dual card slots and the like. Here are the specs:

Number of effective pixels 51.4 million pixels Image sensor 43.8mm×32.9mm Bayer array with primary color filter Sensor Cleaning System Ultra Sonic Vibration Storage media SD Card (-2GB) / SDHC Card (-32GB) / SDXC Card (-256GB) UHS-I / UHS-II*7 Lens Mount FUJIFILM G mount Sensitivity Standard Output AUTO1/AUTO2/AUTO3 (up to ISO12800) / ISO100-12800 (1/3 step) Extended Output ISO50 / 25600 / 51200 / 102400 Viewfinder 0.5 inch Approx. 3.69 millions dots OLED Color Viewfinder Coverage of Viewing Area vs. Capturing Area: Approx. 100% Eyepoint: Approx. 23mm (from the Rear End of the Camera’s Eyepiece) Diopter Adjustment: -4 – +2m-1 Magnification: 0.77× with 50mm Lens (35mm Equivalent) at infinity and Diopter set to -1.0m-1 Diagonal Angle of View: Approx. 38° (Horizontal Angle of View: Approx. 30°) Built-In Eye Sensor LCD monitor 3.2 inch, Aspect Ratio 4:3, Approx. 2,360K-dot Tilt-Type(Two Direction), Touch Screen Color LCD Monitor (Approx. 100% Coverage) Movie recording [Full HD (1920×1080)] 29.97p / 25p / 24p / 23.98p 36Mbps up to Approx. 30min. [HD (1280×720)] 29.97p / 25p / 24p / 23.98p 18Mbps up to Approx. 30min. Power supply NP-T125 Li-ion battery (included) Battery life for still images*8 Approx. 400 frames When GF63mmF2.8 R WR is set. (Auto power save ON) Continuance battery life of movie capture*8 [Full HD] Approx. 145min. *Face detection is set to OFF Actual battery life of movie capture*8 [Full HD] Approx. 70min. *Face detection is set to OFF Dimensions 160.7mm (W) × 96.5mm (H) × 66.4mm (D) / 6.33in. (W) × 3.80in. (H) × 2.62in. (D) (Minimum Depth : 46.0mm / 1.81in.) Weight Approx. 775g / 27.3oz. (including battery and memory card) Approx. 690g / 24.3oz. (excluding accessories, battery and memory card) Accessories included Li-ion battery NP-T125, Battery charger BC-T125, Plug adapter, Body cap, Strap clip, Protective cover, Clip attaching tool, Shoulder strap, Cable protector, Hot shoe cover, Sync terminal cover, Owner’s manual

The camera incorporates a large sensor, approximately 1.7 times the size of the full-frame sensor. It has a rangefinder style design, and all the features are packed in a lightweight 775g body.

The Fujifilm GFX 50R is already on B&H, and preorders start tomorrow. It retails at $4,500 and the shipping starts in November 2018.

Fujifilm GFX 100S

Along with the launch of the GFX 50R, Fujifilm has also announced the development of the GFX 100S. Again, this was rumored before, but now it has been officially confirmed by Fujifilm. The 100MP beast is still not in production, though, but Fujifilm has rather announced “the concept.” Still, the company has revealed some details of its 100MP medium format camera which is yet to come, and there seem to be plenty of “word’s firsts:”

It will incorporate Fujifilm G Format sensor with the world’s highest 102 million pixels

The first medium format mirrorless digital camera to incorporate phase detection pixels throughout the entire sensor (coverage ratio of 100%)

The first-ever medium format digital camera with built-in image stabilization technology

The world’s first medium format mirrorless digital camera equipped for shooting 4K videos

Lightweight, robust vertical grip and integrated magnesium alloy body

Although the development of the Fujifilm GFX 100S is now officially confirmed, it’s still not revealed when exactly it will be available. It could be some time in 2019, perhaps ahead of the next Photokina (which will be held in May). The price hasn’t been revealed yet either, but some sources write that it will retail at $10,000.

Buyer’s Guide

Although most of the rangefinders we’ve highlighted here are designed for hunting purposes, there is an important distinction between them and rangefinders used for other purposes. This Buyer’s Guide will help you select the right rangefinder by focusing on some of the major factors that set the best apart from the pack.

Priority

The major distinction in priority boils down to ‘first priority’ versus ‘second priority’. First priority rangefinders are typically classified as those widely used on the golf course. In these situations, there are generally zero obstacles between the user and the object they are targeting.

Second priority rangefinders are those used for hunting. In these situations, the user is often in a blind or screened by some object between them and their target. Hunting rangefinders will ignore the first object in its line of sight and provide an accurate reading on the second object, which is usually your target.

To be clear, first priority rangefinders can be used for hunting and second priority rangefinders can be used on the golf course. However, the product best designed for your intended use will be the best product for your money. Keep in mind that some laser rangefinders provide the ability to switch between ‘first priority’ and ‘second priority’ modes.

Distance

Distance is one of the metrics that you have to be really careful about when shopping for rangefinders. Many manufacturers market their rangefinders with names that imply the maximum readable distance you can achieve with that unit. Many units, however, will only achieve that distance under ideal circumstances.

If you’re an experienced hunter, you know that perfect conditions are rare. The opposite is more often the case, and in these situations, many rangefinders will only provide accurate readings at well under half of its maximum stated range. In most scenarios, it is best to seek readings at about one-third of a rangefinder’s maximum stated range.

Reticles

Certain rangefinders use reticles that are essentially black lines superimposed over the object you are ranging. Others have LED lights that are invariably adjustable. Deciding which is best can largely depend upon your preference, but here are a couple pros and cons of both.

Black line reticles are useful in good lighting situations but they can often be indistinguishable against a dark background or in shadowy scenarios. LED reticles, on the other hand, are great in low light situations but can be drowned out by ambient light in bright conditions. These LEDs can also destroy your night vision when used in the evening.

So, what’s the best of both worlds? There are several rangefinders on the market that offer black line reticles with a button for backlighting. This backlighting is typically much less harsh than LED lights and still allows you to view essential display information in all light conditions.

Frequently Asked Questions

Bradley A. Fiske is credited with the invention of the first rangefinder (1). Did you know that? Well, even if you did, our Frequently Asked Questions section will hopefully provide answers to a few more common mysteries surrounding rangefinders.

What is a ‘reticle’?

A reticle is the crosshair (also known as ‘aiming point’ or ‘circle’) that you see when looking through a rangefinder.

What is ‘HOLD’?

‘Hold’ is the measurement for either above or under a target point (2).

What is ‘MOA’?

‘MOA’ is the time measurement of the angle of elevation to get a zero for scope adjustments.

What is ‘BAs’?

‘BAs’ is the equivalent horizontal range measurement.

What is ‘Mil’?

‘Mil’ stands for milliradians of the angle of elevation to get a zero for scope adjustments.

How much maintenance will my rangefinder require?

Fortunately, rangefinders require minimal maintenance. The most important ways to maintain your rangefinder is to ensure that the optics stay clean and it is handled with care.

How much range should I have?

The answer to this question largely depends on how you intend to use it, but we’ll do our best to provide a general answer. For bowhunters, 100 yards is generally more than enough range, as you should be close to your target anyhow.

If you’re rifle hunting, however, your desired range will depend on a number of factors, including where, what, and how you hunt, as well as your hunting style and proficiency. As you might imagine, factoring all of these unique considerations in means you’re probably looking at a range anywhere from 200 to 800 yards. When searching for a rangefinder, be careful to consider what the advertised yardage is relative to, as specifications can vary from highly reflective surfaces to deer-sized targets.

What can I do if my rangefinder isn’t performing to the range specified?

Unfortunately, some of the cheaper rangefinders on the market today simply don’t provide the quality you need. Before replacing it altogether, though, try swapping out the batteries for a fresh pair and see if that helps.

If you’ve been using it for a long while, it’s always possible that a large impact compromises the alignment of the unit. If you suspect the latter may be the case, the best course of action is to call the unit’s manufacturer.

Are laser rangefinders safe for my eyes?

Yes! All laser rangefinders should be designated as Class 1 laser devices, which means the FDA approves them (3).

Should I get a horizontal or vertical rangefinder?

Again, the answer mostly depends on your preference. However, let’s break it down a little more than that. Horizontal rangefinders are generally wide and flat, which allows the user to steadily grip them with two hands when ranging a target. This makes horizontal designs a great choice for higher magnification and longer distance rangefinders. The only downside is that they’re generally bulkier than their vertical counterparts.

Vertical rangefinders are perfect for carrying in a pocket or securing to your belt because of their compact design. When actually ranging a target, however, they can be hard to hold steady and the image can appear shaky. As a result, vertical rangefinders typically offer lower magnification than their horizontal counterparts.

Summary

A quality rangefinder will take the guesswork out of distancing targets, whether you’re an avid bow hunter or you prefer to use a rifle. We hope that you’ve found the information in this article useful and we wish you the best of luck finding the right rangefinder for you!

Nikon mengumumkan DSLR full frame terbarunya, yakni tipe D850. Kamera ini dibekali dengan spesifikasi tinggi, salah satunya adalah sensor CMOS tipe back-side illuminated yang memiliki ketajaman 45,7 megapiksel.

Tipe sensor ini diyakini bakal membuat kamera bisa menangani situasi low light dengan baik, meski ukuran megapikselnya sangat tinggi. Sebagaimana diketahui, biasanya tingginya hitungan megapiksel menjadi indikator rendahnya kualitas pengambilan gambar dalam kondisi low light.

Nikon D850 juga dibekali otak pemrosesan gambar teratasnya, yakni Expeed 5. Perusahaan asal Jepang ini sengaja melepas low pass filter, yang biasa digunakan untuk mengurangi efek moire. Tanpa adanya filter ini, maka foto yang dihasilkan mestinya akan sangat detil.

Kemampuan Nikon D850 lainnya adalah soal perekaman video. Kamera ini mampu merekam video 4K UHD dalam 30 atau 24 frame per detik, dan video 1080p dengan frame rate maksimal 120 frame per detik. Ada juga kemampuan merekam video timelapse 8K.

Soal fitur pendukung pemotretan, Nikon D850 dibekali dengan 153 titik autofocus (99 cross type), sebagaimana yang dipakainya di tipe D5. Nikon D850 juga mampu menjepret dengan kecepatan 7 frame per detik pada resolusi penuh 45,7 megapiksel. Kamera baru akan mengalami buffer setelah pengguna menjepret 51 foto RAW 14-bit, atau 170 foto 12-bit.

Nikon D850 bisa diatur agar memotret tanpa bunyi (silent), memiliki satu slot memori XQD dan satu SD, baterai yang sanggup menopang 1.800 jepretan foto atau 70 menit video, serta memiliki sebuah layar LCD 3.2 inci yang bisa ditekuk. Untuk urusan konektivitas, Nikon membekali kamera ini dengan WiFi, Bluetooth, serta Snapbridge.

Nikon D850 akan dijual dengan harga 3.299 dollar AS atau setara Rp 44 juta. Harga itu hanya untuk pembelian body Nikon D850, belum termasuk lensa.

The Nikon D850 surely has to be one of our new favorite DSLRs.

If you look around at various reviews of the Nikon D850 on the web, they’ll most likely rate it as one of the best cameras ever made thus far. In truth, it really does perform very admirably and it absolutely does have a great sensor at the heart. Professional photographers that were considering making some sort of move since the Nikon D810 hadn’t been updated in awhile have an option that is going to last them a few more years before the industry changes yet again. That statement is more or less the basis of my review. The days of being able to know that your camera won’t be updated for four years are probably gone, but that doesn’t mean that you won’t be able to take great photos with it long after it has been updated by some shiny new thing. The Nikon D850 is a fantastic image taking device and tool in the hands of the right photographer. It has a lot of great technology at the heart, but a part of me is wondering about its futureproofing.

One of the biggest features of the Nikon D850 is the 8K timelapse. Photographers these days are really needing to sometimes shoot more video in some way or another but there hasn’t been a total convergence of the mediums yet. So very personally, I truly wonder how long 4K video will be around and when 6K or 8K video may be the new thing. The Panasonic GH5 does 6K video already, and at the heart of it all what I really wonder is how fast is technology going to try to progress as these manufacturers try to outdo one another while constantly trying to disrupt the industry and provide less and less stability to the creators that they’re going for. Of course, it’s up to us creators to adapt. And we do. In biology, this is called cladogenesis–and it’s the process of rapid evolution to keep up with an environment. Just think about it: two years ago we were stricken by the Canon EOS 5DSr. But now we’re all in love with something else. That’s marketing and evolution for sure, but I think that we need to remember is that there may never be some sort of stability again. Nikon D850 owners/buyers should really remember this as mirrorless cameras continue to grow and capture more market share.

Pros and Cons

Trying my hand at a painterly technique with the Nikon D850

Pros

Fantastic image quality

Built like a tank

Buttons that light up

Touch screen makes the menu navigation so much better

Great color depth and versatility

Wifi and Bluetooth

Putting the ISO button on the right side of the camera by the grip is the better long term strategy

Weather sealing

Lots of video options

Dual Card slots

The best viewfinder of any DSLR that I’ve used, but still not as great as many older medium format DSLRs and SLRs.

Cons

Slower autofocus than the Nikon D810 in some situations

I wish the white balance levels were a bit more adjustable. Many of you may groan about fixing it in post and I know photographers that would want to smack you accordingly. But I maintain the judgement that having a consistent, film-like white balance can help you in the editing process so much more when it comes to both exposures and working with color channels.

Sort of shocked that the dual card slots aren’t both SD; I don’t know anyone that used XQD. Sony, the developer of the card, doesn’t even use them in their still cameras

I’m over DSLRs at this point except if they’re medium format. The viewfinders are bugging me now.

Gear Used

The Nikon D850 was used with the 28mm f1.4, 24-120mm f4, 16-35mm f4, and the new Irix 15mm f2.4 Blackstone. The Nikon SB500 was also used during certain shoots. For video, I used a Rode Shotgun microphone.

Ergonomics

If you look at the Nikon D850, you’ll notice a fair amount of changes to a camera that is still more or less the same shape as the Nikon D810. But there are a few key updates you’ll notice more when you hold it, use it, and bring it up to your eye. For starters, there’s the Nikon D850 branding on the top front side.

When you look at the top of the Nikon D850 you’ll see that the pentaprism shape is now different. The reason for this is because Nikon removed the pop-up flash. Everything up top here will all look familiar to a seasoned Nikon shooter.

At the top right of the Nikon D850 you’ll spot the multi-control wheel. There are buttons for metering modes, camera modes, white balance and quality. Then below this is a wheel for drive modes.

On the top right side of the Nikon D850 you’ve got a big LCD screen to look at and change a variety of settings. Nikon also opted to put ISO control here as opposed to the left side–which we’ll get to in a bit. Video recording functionality is also here as well as exposure compensation. In use, this makes a lot more sense.

To the left of the Nikon D850 you’ll spot a whole lot of ports and connectivity. There is USB 3.0, HDMI, a headphone jack and a microphone jack. When you combine all this with Nikon’s newest initiative to give their lenses an electronic diaphragm, you’ll get something more tailored to video shooters. However, Nikon still has to compete with both Canon and Sony on that front.

Turn to the right side of the Nikon D850 and you’ll spot the dual card slots. It takes SDXC cards and an XQD card. For what it’s worth, I don’t know a single photographer who actually uses XQD cards. Lots of computers still have SD card slots, but not XQD slots.

Turn to the back of the Nikon D850 and you’ll spot some new tech here. The LCD screen tilts up and down as well as comes out. In addition to that, there are a few buttons on the right and a number of buttons on the left of the screen. New to the Nikon D850 is this FN2 button which can be programed to do various things. There is also direct flash control wired into another button.

Of course, there is also the big, beautiful viewfinder. Nikon’s viewfinders have always impressed me more so than Canon’s and part of this comes from the fact that I’m still legally blind. With my Mamiya RB67, I use a -4 diopter, and the fact that the Nikon D850 goes down to -3 will make it a bit easier to work with–though this viewfinder is nowhere as large as the massive prism on the Mamiya.

Build Quality

At one point during the Nikon press trip, the Nikon D850 took quite a splash from the whitewater river. But it survived with no issues; my shirt on the other hand… In addition to that, I took the Nikon D850 and the 28mm f1.4 out into a small rainstorm here in NYC. They both survived with no problems. I’m very confident that the Nikon D850 will survive most of what you throw at it as long as it has all the ports closed shut.

In the hand, the Nikon D850 feels really great and surprisingly never hurt my wrist at all carrying it all day long. It’s amazing that Nikon was able to pack this much into a camera like this. Professional photographers looking for a solid DSLR will find it with the Nikon D850 for sure.

Ease of Use

What Nikon did to really up their game in the ease of use area starts with the placement of the ISO button. With previous high end Nikon cameras, the mode button was on the right. But the ISO button is there now and it makes the experience of shooting without leaving the viewfinder so much more straightforward right out of the box. Putting the mode button along with the white balance and quality buttons on the top right is a welcome change.

Then there’s the other big part: the touchscreen. Navigating Nikon’s menus is so much faster now. Nikon’s menus were always pretty simple and this lets you cut to exactly where you want to go. Plus when shooting video or some stills, you can touch the LCD screen and shoot immediately. People who are brand new to photography and have some disposable income that want to buy the Nikon D850 and shoot it in auto will not only earn the scoffs of many photographers, but also may have a tough time with it due to its higher levels of complexity and there being no auto mode. but veteran Nikon shooters and photographers who are coming over from Canon may find things here that they really like.

Nikon also added two ways to move the autofocus point around: there’s a little joystick and there’s the D pad. That’s quite a bit to give photographers!

Autofocus

Now here’s where I was scratching my head for a bit until I showed it to a veteran Nikon shooter and he agreed with me. The Nikon D850 in my opinion is slower to autofocus than the Nikon D810 by just a bit. You won’t notice it unless you’ve shot a lot with the Nikon D810. But it’s also not always as accurate. There were times that it has missed the focusing for sure but to its credit, the Nikon D850 was trying to focus in very difficult lighting conditions.

Believe it or not though, I think that the Sony a9 has a better focusing system than the Nikon D850. Yes, crazy right?

Tracking focusing for the Nikon D850 worked very well, however. And in situations where you want to get even closer to the action, the DX crop mode is really great.

Metering

The Nikon D850 follows the Sunny 16 methods of metering to a T more or less. But as I was working with the camera, other journalists started to think that the Nikon D850 needed to be underexposed a bit to get the best results for editing. That way you’d be able to pull in more from the highlights and push the shadows. That’s more or less what I did in really contrasty lighting situations. But otherwise, I relied on the Nikon D850’s great RAW files to get what I wanted and needed out of Capture One Pro.

Image Quality

Image quality from the Nikon D850 across the board is absolutely solid. DXOMark confirms this and the Nikon D850 has a sensor with results that are very forgiving providing that you know what you’re doing. Most photographers may use Adobe Lightroom; Lightroom will do a good job but not as well as Capture One Pro–which can be set up to be just like Adobe Lightroom more or less but with more emphasis and focus on certain parts of the photo.

One thing that I should really talk about first and foremost is the square crop mode. I love it and I’ve always been in love with square photos due to the simplicity that they can pack into an image. They’re both the simplest and the most complicated images to make.

Before I go on, here are some other images that I really like.

Video

So if you haven’t subscribed to our YouTube channel, you should really do so right now! Part of my testing with the Nikon D850 involved shooting these two videos of Kevin Mullins and David Hobby over at the Fujifilm festival.

Granted, these are pretty simple, journalistic videos. But they go to show that anything and everything these days are more than good enough and that all that matters is the content. This is something that I always want to reiterate to photographers and creators.

RAW File Versatility

Edited

I purposely chose this scene because it encompasses what a lot of photographers will be looking for in the Nikon D850. This image of Mike from Steve’s Digicams was shot using a Speedlight in HSS mode. It showcases dynamic range and skin tones both. If you’ve gone so far as to edit color channels, you’ll understand that this is difficult because his skin tones are associated with the dirt in the background and his LL Bean logo. Plus his hair isn’t far off and the greens in the hat aren’t far off either. However, by tweaking the dynamic range of each color channel and then the overall scene, I was able to get this photo above.

Original

Here’s the original. The original image isn’t so bad either.

High ISO Output

ISO 12,800 on the Nikon D850 is very usable and in my experience, I haven’t really needed to go above that practically. But the High ISO output from the Nikon D850 is indeed very good. I haven’t been able to make prints with the files though but I’m very confident that I’ll be able to make big 11×17 inch prints with no problems at all.

I’m over DSLRs at this point despite the fact that I acknowledge them as fantastic image making devices.

The Nikon D850 is an absolutely fantastic camera in so many ways. Need great image quality? The Nikon D850 arguably has some of the best on the market though I’m not sure how much of a difference photographers will notice vs the Nikon D810 and the Nikon D850 when you look at the images as a whole. Your clients surely won’t notice. The only way that anyone will truly notice at this point in photographic technology is by printing a whole lot. Besides the imaging sensor though there are a lot of nice touches to the Nikon D850 like the fact that the buttons now illuminate when you activate the LCD light, the ISO button, the touchscreen, 8K video, and Nikon’s attempt at their best viewfinder yet. Then there is the weather sealing, etc. Where I feel lke it falls a bit short though is on autofocus.

Photographers and professionals will do great work with the Nikon D850 for sure.

But on a personal level, I’ve taken this into consideration very carefully. On a recent Canon press trip, a Canon rep was touting how mirrorless cameras were needing to become sizes of DSLRs and make lenses are big as the offerings from DSLRS. But he didn’t incorporate the weight at all, and how they’re still smaller overall. And that’s what I’m all about these days. the Nikon D850 is very capable but it could have been done smaller, with an EVF, etc. Even if it was still F mount, I would’ve considered springing for it and even switching my Sigma glass mounts and my lights. But DSLRs take up so much room in my camera bags when I need to go on gigs and go shooting. As I shoot more medium format film, I’m shocked at how comparable they are in sizes. Personally, I still get more from medium format film for the size and weight factor. I’d rather go a bit heavier and get a larger negative. Plus, EVFs let me do so much more at this point.

Sony and Fujifilm at the moment have my heart; but Nikon was very close.

Either way, my personal feelings don’t at all negate the fact that the Nikon D850 is a fantastic camera.

The Nikon D850 wins five out of five stars and our Editor’s choice award. Want one? Check out Amazon for the latest prices.

The Nikon D850 is surely one of the best DSLRs made thus far. But I'm getting over DSLRs at this point. The Nikon D850 surely has to be one of our new favorite DSLRs. If you look around at various reviews of the Nikon D850 on the web, they'll most likely rate it as one of the best cameras ever made thus far.
