Dear sirs, I am wondering wich camera has better low light performance. I will never shoot higher than I.S.O. 24,600 so this is only a battle of noise reduction and a cuple other factors.

My A7s has developed a problem when filming. At higher apertures and shutter speeds, I line up the shot normally using the monitor/viewfinder and then when I hit record the image instantly burns out and turns brighter by around 5 stops.While still recording, I have to then dial in a balanced image again, which is fine for a while until I tweak the aperture again and, boom - the image jumps another 5-6 stops brighter. After a couple of iterations of this, pretty soon I'm on 1/8000 at f32 with...

Does anyone know if the above camera has an in camera rating system like the canon 5d had?I'd love to rate or star an image out in the field so it transfers to the computer with a tag/star in it's info. Can't find info on this anywhere so would appreciate a tip if anyone has found a workaround on this. Thx / T.

Yesterday, after trying a video with PP7 setting (s-log2) earlier, a rapidly developing opportunity came my way, so I simply switched to P mode to shoot a series of Jpegs of the action. I found out the s-log2 setting was NOT mutually exclusive of modes other than video, and did what I could to work the resulting jpegs to decent shape. Has anyone much experience or advice for better remedies (aside from searching the menus to get to a stills profile) to utilize this setting? Also, are s-log2 &...

I am very strongly considering purchasing a 35mm/1.4 lens for A-Mount in the very near future (possibly within a week).  The uses will be Wedding Photography and Videography (not simultaneous).  I need the 1.4 Aperture for Video low light and I think the 35mm is a pretty versatile focal length for all day usage in both photography and videography. My other lenses are the Sony Zeiss 24-70/F2.8 and the Sony Zeiss 135/F1.8.  I am thinking the 24-70/F2.8 on one body all day  and then the 35mm/1.4...

I just purchased a Tamron 25-135 Adaptall 2 Lens, and an Adaptall 2 to NEX Adapter. The adapter and lens fits on my NEX-5n fine, but wont fit on my A7s. I also have a EF to NEX adapter I bought long before the A7s was released, and it fits on my A7s. Also, my 16mm lens I bought with my NEX-5n fits my A7s. Why is this adapter any different? I bought it from a chinese store on ebay. Any suggustions on what to do now? I don't want to keep buying adapters that don't work. Thank you.

I just bought a Sony A7s and I can't figure out how to set a lower ISO than 3200. I tried to change the Picture Profile setting from PP7 S-Log 2 to PP-off, but it still jumps from 3200 all the way to Auto Mode, without letting me select any in between. Can anyone please suggest how I can fix this? Many thanks, Albez
