What I dreaded the most going with the a7 III were the skin tones... I half expected them to be a nightmare, and most of what I'd seen online didn't inspire much hope. But I shot a few clips at the post office this morning (mix of daylight/fluorescent), and the colors look fine to me, especially since I didn't do much in the way of color correction. So far, finding the Sony a joy to shoot with...
Edit: A more accurate representation of the colors can be found here.
