I shoot weddings and I currently use two 5d mark ii bodies which are for the most part a pleasure to shoot with. I know many of the most famous wedding photographers shoot with these as well (or, used to). My question is, how the heck do you overcome the shortcomings in autofocus? The center point is great and can even track action reliably, but it's obnoxious to have to poorly compose a shot in camera all the time because that's the only point that IS reliable. Tracking with the outer points is a joke. Focusing and recomposing with the center point during a wedding in dark venues using large apertures often does not work because people are constantly moving, and is tiring. I end up having to crop the crap out of shots on post to get them composed somewhat they want I wanted. Am I missing something here? Or is the exact reason so many jumped on the 5d III when it came out?
