I purchase my A7S in Hong kong. It works exactly as I expected, however, the PWR SAFE START does not work at all! I tried to set it to 15sec, minutes, etc. It never go to sleep mode. Anyone encounter this problem? I tried to turn off WIFI, RMOTE CONTROL, switch between PAL/NTSC, remove all APPS, restore factory settings, change different lens, and any other possible options, but still does not sleep....

Hi I am considering to acquire an A7s in replacement for my Canon 5D III. I have some doubts however. I had an A7r using it with the FE24-70 and FE55. No FE70-200 was available by that time. The LA-EA4 was not very usefull on the Sony 300G as it had no OSS. I am wondering about two things a. How is the performance of the FE70-200 in terms of AF? b. Does anyone have experience with the Metabones III Adapter and a Canon 300L IS 2.8? BIF or Aircraft spotting? I own the Canon 300L IS and i'ld...

This morning I was watching this A7S vs GH4 review https://www.youtube.com/watch?v=O76Ci8MDGhI and I was shocked the myriads of mistakes this reviewer made. After learning from Tony Northrup how to do equivalence calculation properly, this reviewer messes up things completely: he simply ignores to do the proper aperture conversion math. Another mistake is that he simply ignores that (pro and advanced enthusiast) videographers don't use autofocus at all, and they are not rely on native lenses;...

Hi, I had read this great article: http://www.josephjamesphotography.com/equivalence/#dr But I feel a little bit confused with this part. Is there a strong (theoricall) reason to explain that sensors with higher pixel densities would have higher DR ? What would be this theorical gap, can it be measured  ? Does it explain that the Sony A7S does not have very high DR ? Thanks for your answers, Christophe

I know on the A7s there is silent shutter mode, but when you have a flash attached you can not shoot in silent shutter mode, so I was wondering if you can control the sound of the shutter if possible? I'm also curious as to technically why you can't shoot in shutter silent mode when a flash is attached?

I will be buying a new camera in the next few weeks for my professional work, I am a headshot photographer in Vancouver BC, don't need complicated video. I am really confused about purchasing the Canon 6d or Sony 7s.   1 - Money is an issue, so the 6d is more economical and seems to have outstanding low light abilities which is something I'd like to test. Canon wins 2 - Exciting Appeal, love what Sony is doing.  They seem to be working harder than any other camera manufacturer to offer value,...

Hi, Thanks for the review. Yes that's a great camera for photography and video. I use this camera for video. Could you let me know how to use steady shot option on this camera please? I am using Canon's glass with this camera. It seems like this option is not working at all. The other option I want to access is TC which is also disabled. I returned the first one because those features were not working but the new one also doing the same. Thanks in advance.
