Like others have mentioned, the reason I still use the Canon Mk3 is for colour and simple out of the box video. It just looks good. I work in a studio, where we do a lot of product video. Once I tried to test the A7s and couldn't get my colours accurate. Yes the image was very nice, but the red showing in the video out of the SONY simply was not the same red as the product was, whereas the CANON was the exact same colour. For my studio shooting I'm not interested in grading every image, or even setting up a profile, I want to pick up the camera and have perfect colour just by setting a white balance. I was shooting rec 709 on the SONY btw -I feel that this should have given me good colour representation. Any one else have this experience? Any real colour comparison tests done out there?
