I got my 5D Mark III yesterday. After shooting with it yesterday afternoon and this morning I have to say you couldn't pry this thing from my cold dead hands. I freaking love it.
I couldn't agree more. As someone who owned a 7D and 5D Mk II simultaneously and struggled between wanting the speed of the first and the image quality of the latter, this has met all my expectations and then some. I have a serious concern about in camera JPEG quality right now, but that's it. I never shoot in JPEG, but with the lack of decent RAW support at this point, thought I would try it. I expect they will resolve it with firmware.
