I just wanted to start a thread for those who have any questions or comments on settings that they really like on the 5D Mark III. I have seen the odd post on AF settings but that's about it.
Myself personally, I shoot mostly portraits, so I'm just using the 15 point set up with the base focus point and I am pretty happy with that set up. The camera is pretty new so I haven't had a ton of time to experiment try out everything in the menu. I did have limited to success with HDR modes.
I have heard of people reprogramming the depth-of-field button on the front of the camera to different functions, which I am definitely curious about.
