I own and use a 5Dmk3 for my studies and some of my clients for a few months now. I would have to write a sensor reading doesn't even come close to showing off this bodies attributes. Canon still have best lens choices if you can afford them, just show in raw if you might want more dynamic range or change settings in Picture Styles ( easy ). This is the fastest focusing body in this price range helping any one get the shot ( not missing it ), due to focus hesitation. Build quality is still best in class except for shutter count, Canon blew that one, but swaping out the mechanisium is always a option if you are a Professional down the line. Only because I'm able to buy one FF system did I invest in the best for most situations like a pro. I did care about just studio resolution becasue I don't have time for this in the field! The 5Dmk3 is the best in the field hands down. No hesitating focus, best lens choices and buid quality. Dxo's mark is for ametures.
