On the verge of buying an A7s and coupling with an Atomos Blade or Shogun.
I had a little play with the camera, but only recorded internally.
I noticed, in gradations in shadows, flares, etc... some noticeable banding. The crunchy stuff.
I understand it's 8-bit overall... but can someone help me understand how recording via 'uncompressed' HDMI out will improve the image?
Isn't it basically H.264, wrapping in Sony's codec nonsense, which gets recorded internally?
So going uncompressed -> 422 (at 1080 or 4K) is going to improve... what? Anything noticable?
