Sony A7S 4K full frame mirrorless camera announced Sunday at NAB? In: Cameras Posted April 4, 2014 12mp = 8mpx in 16/9 = 4K full sensor read out = amazing low light for stills = amazing high FPS for stills = amazing still quality (see D700 12mpx pictures, 6years old camera...) = smaller files to work with = finally the first world camera with no compromise : 4K + FF stills in a compact body. What I have been waiting.... Yesterday I had a 2h conversation with a friend about how should we do with GH4 because it sucks in stills (I had 5D2, Fuji Xpro, XE1, GH3, Olympus EM1 ... I know what I talk about : M43 sucks for landscape as it has very poor colour depth and DR, go on 500px.com and compare shots done with 5DIII, D800 and EM1 (wich is a pro body as well) ) so we were wondering what to do as we are 50% in video and photo. Sony .... Please don't disappoint with any major issue, and take my money. RIP GH4 GH3 has better dynamic range than the 5D III. Go look at the sensor charts on dxomark. It doesn't quite have the resolution, though.
