I have only had the 5D3 for a few days now and I know there are some folks complaining a little about it but I have to say I love it so much better than the 5D2. The one thing I absolutely love is knowing that it will accurately focus almsot 100% of the time, no matter what focus point I select, at f/1.2 on my 50mm. I love that lens and I couldn't use it much more than 1.8 on my 5D2. At 1.2 it almost always missed focus and I had to focus and recompose which would throw it off even more. Being able to use it whenever I want now has opened up a whole new world for me. Anyways there is link below to a picture I took during a senior session. It isn't supper sharp, but the 50mm 1.2 isn't a supper sharp lens at 1.2 and I don't need it to be.
