I was not thrilled with the "looseness" of the kit lens with my XT. I wanted a better quality general purpose replacement so I bought a Sigma 28-105 2.8-4 DG. I have found that the DOF is very tight and I am having difficulty getting focused shots. When they look good in the viewfinder, the picture is focused slightly off my target. Some pictures have come out really sharp, but many I expect to be good are not. Is this something I just need to become more skilled at, or could the lens be faulty? The kit lens definately has wider DOF across the board.
