indeed, every video I've seen from the 5D3 looks soft, even the 1080p curtain flick "straight from the camera" that appeared yesterday and quickly disappeared
I don't know how they managed that, after using a sensor that's exactly 1080p times 3 so downsampling becomes easier
so yes, it has no moire/aliasing, massively improved high ISO, and hopefully a better codec (no all-I samples out yet), but limited to 8-bit 4:2:0 and looking this soft... lots of people seriously rethinking 5D3 for video right now
