Hi I have had both these cameras and in time sold them both. I loved the colour from the 5d mark ii, really was disappointed with the colour from the 5d mark iii. I felt as if it just looked flat and boring, and i find this kind of thing is very hard to match again in post production. I moved to a different brand but sometimes i feel like i very much miss the 5d mark ii and its lovely skin tones and colour, something i feel the mark iii lost. I also found the 5d mark iii files to handle exposure pushing far worse than the 5d mark ii. This seems bizarre to me. But ive tested it many times now on old files and the mark iii seems to band far worse and show crappy shadow noise worse than the mark ii. Am I alone in this. I know many mark iii owners will be quick to defend the mark 3 but i was left feeling very much that they had improved high iso at the expense of dynamic range or something. and autofocus was better but meh, give me those tones back.
