This may be a dumb question but why are so many more AF point beneficial. Nikons d300 has 51 while most of canons line is stuck at 9, but does that matter? Personally when I am shooting, I place the camera (Rebel XTi) on auto focus on the center AF point. I place the subject that I want in focus in the center, half press the shutter and hold, reframe the shot, and fire. Is there something flawwed with this method? If not, I would feel that with all of those AF points it could be rather cumbersome. I am sure that there is a benefit to them, just curious as to what it is. Thanks!
