A first look at the Sony Alpha 7S 12MP full frame with 4K output

@ Stu 5 – I agree with the comparison with the 1Dc to a certain extent, except for a couple of things. Some may value financial savings over physical size. The 1DC is about $9000, whereas the A7S is likely $4000 including Atomos Shogun.

Secondly, the 1DC’s 4K codec produces very bloated files at 8bit 4:2:2, whereas the Shogun will allow 8bit output to 10bit ProRes file. The initial demo videos show that the 4k output of the A7S is extremely good, at least as good as the 1DC, perhaps even better.

The 1DC is also apparently as kludgy to operate for video as the 5D Mark II. No dedicated record button, no Movie mode on the mode dial, no focus peaking, no zebras, and a host of other things that speak of a bolt-on function rather than integrated quality. Sony looks like they have made this a video first, stills second camera, with all the function that entails.
