Laowa 90mm F2.8 CA-Dreamer Macro 2X lens: All you want to know!
Recently, Venus Optics has unveiled the new Laowa 90mm F2.8 CA-Dreamer Macro 2X lens in China, which is expected to hit the overseas market on May 23rd. As the ninth member of Laowa’s Macro lens lineup, the 90mm Macro lens is an ideal option for both novices and professional photographers, with a kaleidoscope of choices in terms of focus lengths and scenes.
A brief introduction
For those who just embarked on their macro photograph journey, there is a need to master some basic knowledge about the minimum focusing distance and macro lens.
Let’s start with the former one. The minimum focus distance is the shortest distance at which a lens can focus. In the case of DSLR Cameras, the distance to the subject is measured from the focal plane mark on the camera body (distance B), not from the front of the lens (not distance A).
Then, it comes to the most important question: what can a macro lens be used for? A macro lens is a camera lens designed for photographing small subjects at very close distances. They can focus much nearer than normal lenses, allowing you to fill the frame with your subject and capture more detail.
They are typically used when photographing insects, plants, and small products, but are versatile enough to be used in all sorts of situations. Virtually every subject has interesting details which can make for fascinating close-up photos.
Design and Handling
Even if you have little knowledge about macro lenses, you’re probably familiar with the Laowa 24mm f/14 2X Macro Probe Lens, which earned its fame for its “weird” looking and excellent performance. Laowa has long been famous for its unusual unique lenses which have minimized aberration and available prices.
The Laowa 90mm F2.8 Macro 2X is a macro lens designed for full-frame mirrorless cameras with four mounts: E, R, Z, and L. Despite its 2x magnification, Laowa still brings the weight and size of the lens under control, with a filter thread size of 67mm, a lens size of 74mm*120mm, and a weight of about 619g.
Compared with other manufacturers' lenses of similar focal lengths, the 90mm macro lens appears to be slenderer, while the smooth texture reflects Laowa’s constant pursue for appearance and materials.
The new 90mm micro inherits its traditional APO or apochromatic technology with 13 aperture blades. What’s new about it is the optical design, with 13 elements arranged in ten groups. There are three ED (Extra-low Dispersion) glass in there and three ultra-high refractive index elements. According to Laowa, ED glass delivers better sharpness and reduces chromatic aberration or color fringing in photographs; meanwhile, ultra-high refractive index elements help deliver a more uniform performance across the lens while allowing the size to be reduced.
Note that the white dot on the barrel stands for F16 which was discarded because of the close proximity of F11 and F22.
As a manual focus lens, the 90mm macro has a manual focus ring that is pretty nicely damped, and from top to bottom there is a wide range of magnification options from 2:1 to 1:10, as well as the focus distance is scaled in feet and meters respectively.
The 90mm macro lens adopts an internal focusing design that extends from the closest to farthest focus inside. For better dust-proof, Laowa has assembled an additional lens at the very front of the lens.
It has a minimum focus distance of 0.205m/8.07ft providing a 180-degree field of view which further benefits better focus effects.
What we had is the L-mount version with 4 screws used to strengthen its all-mental build.
Theoretical Test
In our tests, we've been testing the Laowa 90mm macro, paired with Panasonic's LUMIX S5. Note that the tested lens is an engineering sample, and the commercial version shall prevail.
001 Resolution
We’ll use ISO 12233 charts with the 90mm macro at an aperture range of f/2.8 through f/22 under the normal exposure and show you 100% crops at the center and corners.
It’s clear that the resolution at f/8 demonstrates excellent in the center and at the corner with the best image quality. At f/2.8, the image quality is excellent in the center but slightly soft at the corner which is improved gradually with shrunk aperture.
In short, the overall image quality in the center and corners at all apertures is excellent, thanks to the flat field of the 90mm F2.8 macro lens.
002 Lens Blur
The lens features a 13-bladed aperture diaphragm that can produce relatively round facula. It is worth noting that at maximum aperture, bokeh at the edges presents a lemon-like effect due to loss of light, which however will be greatly improved by shrinking the aperture by a single stop.
focusing distance of 1m
focusing distance of 0.3m
003 Chromatic aberration
Thanks to Laowa’s unique APO technology, the 90mm macro performs well in reducing chromatic aberration even at the full aperture or 2x magnification.
004 Vignetting
From the GIF, you can see the visible vignetting at f/2.8, which slowly decreases as the aperture is shrunk. At F5.6, almost all of vignetting has disappeared.
005 Lens distortion
In general, a lens with longer focus length is prone to produce pincushion distortion. As tested, the 90mm macro exists a slight pincushion distortion, though which can be improved in the postproduction.
006 Focus breathing
Focus breathing, as we all know, has plagued macro lenses for a long time. There is unfortunately no better way than avoid switching the focus ring as much as possible in video photography.
Real-world Experience
In fact, it’s not easy for novices to control focus well in that there is no stabilization available, and the targeted subject is moving, all of which will make handheld shooting much more difficult.
To deal with that, we could first set 1x magnification, and by moving your body or arms, bring the focus point within the range you want. If you want the subject larger, you can then increase the magnification. This can shoot a more stable image and focus more quickly.
What the Laowa 90mm impresses us most is the minimum focusing distance of 20.5cm and 2x magnification.
Note that with the shutter, ISO, and aperture fixed, the image will be slightly darker when using 1x magnification or higher, making it difficult to balance both normal exposure and image quality when shooting handheld.
1x magnification
2x magnification
It’s common to use a macro lens to capture flowers and insects and so do I. But, when I tried to take handheld shots of fluttering bees and butterflies, it was not always easy to capture clear images due to their extreme vigilance yet my long-time manual focusing.
The 90mm macro often creates a very shallow depth of field. In addition, a large aperture of f/2.8 is also not common in actual macro shooting, as most of the area outside the focus will be overly blurred. For example, if you shoot a keyboard with f/2.8, the two letters at the very edge will be defocused to some extent.
In practice, we highly recommend a aperture range from f/5.6 to f/11, which can take into account both the light and shallow depth of field to produce high-quality images.
If you want to highlight a particular point, a large aperture may come in handy.
There are some macro-shooting skills for your reference:
001 Add light source
As the old saying goes, light is a priority in photography, with macro photography being no exception. Adequate light makes it easier for us to achieve normal exposure. But when photographing moving subjects like insects, the flash may "scare" them away. In this case, using a flash diffuser may be a good solution.
A small fill flash can also be fixed to the camera's hot shoe, but the light is usually harder this way. To make the light more natural, we can adjust the angle, color temperature and so on.
002 Use manual focusing
Laowa has taken a different approach from the common pursuit for quicker focus speed by adopting manual focus for all its lenses, which helps to improve image quality in low-light and low-contrast scenes, at the same time making images more impressing.
This is especially true for macro photography, because autofocus usually results in vibrating images.
003 Adopt a tripod
A good tripod is essential to macro photography. You need your camera to be stable and secure to capture those up-close images. Camera shake is more noticeable when working close to your subject so the use of a tripod's recommended.
004 Shoot as much as possible
The fact that more photos you take, the better results you get is always proven to be true. Turn on the high-speed continuous shooting mode, and then press the shutter fast at the moment of finishing focus. You may get a bonus.
005 Take focus stack photos
Focus stacking is a technique designed to achieve a deep depth of field by blending (or stacking) several images together. Each stacked shot is focused in a different spot, so the combined depth of field is deeper than the depth of field produced by any of the individual images. Focus stacking is pretty easy to do, and you can process it later in Photoshop.
Macro lenses can also be used the same as other lenses with the identical focal range. As we all know, the focal length of 85mm has always been the best focal length for portrait photography.
The Laowa 90mm Micro also deserves a lot of praise for its performance when shooting complex images. Thanks to the APO technology, chromatic aberration is almost invisible during sunny day shooting.
Verdict
The macro world always shows itself with usually missed details, which presents more appeal to us for further exploration. Laowa is such a manufacture who is dedicated to producing various of macro gears with great performance and affordable prices. Pre-order is coming soon…
