Am renting a mkiii this weekend. Can any users pls share some setup and shooting tips. I'd also like to make sure I can set up the camera to spot meter off a specific AF point. Am doing a 40th on Sunday so I have a day to get it set up right. Will be using a 50/1.2L.

My other question is, if I shoot raw, does canon have free raw editing software that I can download and use ?

Thanks for any help.
