I was taking photos this weekend and I was noticing that half my photos were not sharp enough especially when the subject is further away from me, like my camera is not recognizing them or something. I use a fast shutter speed and try to keep as steady as possible when I am not able to use a tripod. Could it be a problem with my camera? When I focus on the eyes it seems to be a few inches off where I intended to focus on. BTW, I rarely shoot wide open, so I doubt that is the issue. When I shoot a portrait of people, what AF should I be using? (i.e. AF-S, AF-C, AF-A) I have never took it off AF-C, could that be my problem? Sorry about all the question but I am getting so discouraged.
