Gian (07.23.13, 1:40 AM): This is the most comprehensive review I have come across. Simply great. I have just updated to the d7100 a week ago and I am refining certain things to get the best out of my new camera and this video you posed + comments really help. Just one thing if I may, regarding the focusing system on a particular matter. If one had to shoot night time concerts, say a rock concert, what would the ideal focus option be, ie AF-C or AF-S, and which cluster would you use, the single square, 9,21,51 or 3D. Thx and keep up the good work.
