Own A7s. Had a 5D3. Never used ML on jobs for variety of reasons. Sometimes I wonder about my decision to get rid of 5d3. For stills it's far superior. For video, I find the colors of 5d3 in a different league than A7s. While A7s is better for me in almost every other category (DR and resolution), it wouldn't surprise me if you showed a side by side clip to a regular audience member or client, they may very well prefer the 5d3. Most humans don't care about resolution. They do sense when colors are off. I did a similar blind test between F55, Dragon and Alexa projected in front of producers and the director for a feature I shot last Summer. Alexa won unanimously, Dragon 2nd and F55 last. Despite the Alexa being 2k, the others 6k and 4k, the skin tones won the day.
