Does Sony HVL-60M overheat? PART II
So, yesterday I was not able to overheat HVL-60M indoor, using E-TTL HSS mode. But it overheated in when I provoked it, using full 1/1 power. Today I performed two tests: (1) out-door shooting, using HVL-60M as fill-in flash in bright daylight at 15 meter (16 yard) shooting distance and (2) indoor test, where I just fired flash in manual mode at 1/2 and 1/1 output levels. Test 1, outdoor photography My hypothesis was that using HVL-60M as fill-in flash at sunlight from long distance is pretty hard task because it has to compete with the highlight created by Sun, to fill in shadows.
So, I mounted Carl Zeiss 135mm F1.8 to my Sony SLT-a99 in order to provide space between the subject. Longer distance will stress HVL-60M even more, was my thinking. I abandoned to test the flash in real shoot, saving models. Instead of that I shot a tree :)
I shot mountain pine from 15 meters (16 yards). My camera was in P mode with fill-in flash, 1/160 sec, F4, ISO 100. I had camera in Drive/Lo. I just pressed the shutter button and waited. This as not a real-world situation. Camera just continued and continued, HVL-60M didn't skip any flash. At least I did't notice that. I shot 380 continious shots from the 15 m distance in sunshine until I overheated HVL-60M. So, it's theoretically possible, but I really don't believe that it ever occurs in my practical use. Test 2 People from DPreview forum asked to count flashes-to-overheating at lower power levels. Due to time limits I did this test at 1/1 level two times and 1/2 leve also twice. For some reason, I had slightly different numbers, but here are the results: at 1/1 25-41 flashes until overheating at 1/2 58-64 flashes overheating Conclusion HVL-60M is not going to overheat in real-life shooting scenarios. You are able to provoke overheating, shooting 25-41 flashes at full power or 58-64 flashes at 1/2 power. But it's not worse than Nikon SB-800, about 25 frames at 1/1. Guide number 60 is an advantage and disadvantage at the same time. In most cases you need only 1/32 or so and the flash is very capable then, able to shoot 10 fps endlessly, no problem. But flushing all huge energy at 1/1, stresses output electronics and batteries. In this case heat is your enemy. Would I buy it? No, but because of too high price. At 30-40% lower price, I'll take it and will trust it in my shoots 100%.

Does Sony HVL-60M overheat?
I'm keen a99 shooter and I love my camera. I do lots of low-light-fast-movement performance shooting and my camera does excellent job. I never use flash, but one has to keep it in the bag. As there is no 3.-rd party flash units for new a99 ISO shoe, only Sony flagship HVL-60M left to my shopping list. Still, forums repeadetly warned about overheating. I decided to test that. Yesterday I got HVL-60M from local Sony Concept Store for 3 days testing. These are my initial observations. Summary: does it overheat? Answer is Yes and No. If you really provoke it, then it does. Turn power to 1/1 and it overheats in 24 shots or so. Holy crap, you might think. No. In regular TTL use I was not able to overheat it. How did I test
I charged my Panasonic 2100 mAh AA Li-Ion batteries. They were pretty warm, when I installed them into the flast unit, but this is real-world scenario.
I mounted flash to my a99, turned both to Manual. I selected 1/1 flash power from HVL-60M menu and started to take heavily overexposed photos:
Flash recovery is painful 5 seconds (or so) in 1/1 mode. But keep in mind, that it's a powerful flash, with guide number 60. In real world you rarely or never need full power. After 24.-th shot, overheating icon appeared to LCD.
So, I waited 5-7 minutes or so, until flash cooled down and overheating sign disappeared. In the second part I switched HVL-60M into TTL mode, letting flash determine power needed and started to shoot in Drive/Hi mode. HVL-60M did't skip any single frame. Then I switched camera over to super-hi-speed 10 FPS drive mode, so called Tele-zoom Cont. Priority AE. Again, flash kept up with the pace. I shot 250 shots like that and got bored. There was no overheating whatsoever. Tomorrow I take my camera/flash to outdoor photo-shoot and write about it.

These are my favourite lenses 135 mm F1.7 Zeiss : SAL135F18Z Sonnar T* 135mm F1.8 ZA 85mm F1.4 Zeiss : SAL85F14Z Planar T* 85mm F1.4 ZA They are heavy! Go to gym before 3-hour 2000-frame photo-shoot. And I guarantee, you still are going to break sweat.

Yesterday I had exclusive opportunity to listen superiour Estelon speakers, designed by Alfred Vassilkov and built in Tallinn, Estonia. As Estelon is heading to Europe's largest specialist trade fair for high-end entertainment High End Munich, they had 2 models for listening: Estelon XB and most affordable 16 000 € Estelon XC (all photos are Estelon XC model). We took relaxed 1 hour to go through Alfred Vassilkov's favourite tracks, most of my personal taste. First thing you notice, that sound field and imaging is absolutely translucent. There is a concert hall, church, jazz club or studio, but not speakers -- when you close your eyes. Second observation is, that you start to feel the emotion behind the music -- all the meaning of ones piece is "tele-ported" to listening room with no loss of feeling. Third observation was that I started to notice imperfections and naturalness of instruments. Natural-natural-natural are 3 words how to characterize Alfred Vassilkov's masterpiece. Estelon speakers have exquisite component selection, but what makes it really special is cabinet material. It's made in a special casting process, the use of a proprietary marble based composite and the extensive use of sub-structural stiffening spars breaks up resonance nodes and creates an internal acoustic chamber of non-parallel sidewalls that is all but immune to unwanted standing waves that can cause a colored sound. To develop the cabinet material, having all needed physical characteristics, took years. The result is, that the cabinet is heavy, bigger XA model weights over 80 Kg, and has virtually "dead material" properties. Stay tuned, after the High End Munich, I'll be back at Estelon and shooting their 80 000 € diamond-tweeter flagship model.

Samsung NX300 smart camera Well built, billet aluminum on top and bottom. Camera feels solid and well built. Body is slim, but kit lens add dimensions. Smart means WiFi connected. So, it allows to upload hi quality photos to Facebook, Google+/Picasa, Skydrive etc. But most fun is to use Samsung Smart Camera App in iPhone or Android. It allows to place camera strategically, follow action via remote viewfinder on mobile phone screen and take shots remotely. Use Your imagination... Great AMOLED touch sensitive screen. makes using smart functions easy, like selecting WiFi hot-spot, typing in network passwords or account names. Great focus speed and accuracy in normal conditions due to innovative hybrid focusing method. NX300 has both phase detection and contrast detection areas on the sensor. Still, struggled in low light condition in longest focal length position. 20 Mpix is a tad too much for APS-C, I would prefer 16 Mpix and larger pixels for better low light performance and ISO capability. Shooting with slow kit lens in weak light is pain. Small aperture forces to use high ISO and long shutter, causing either bad noise or motion blur. Even pretty well lit situations may require ISO 1600. That's not good, as noise is already kicking in. Great cam for gadget lovers. Photographers stay most probably with their Canon/Nikon etc hard core photo gear. But when iPhone or Galaxy is not enough, it's time to move over to Smart Camera now.
