I took near 600 pics at an indoor wedding reception with my D7000 in Aperture priority and only got 60ish keepers.... I was using a 1.8 50mm lens, no flash. All pictures were either out of focus (Dof is practically zero I found at low fstop) or blurred (shutter speed was too slow at higher fstop)........ very nearly tossed the camera in the punch bowl... any advice would be appreciated...
