Canon Normal EF 50mm f/1.8 II Autofocus Lens with Xsi

Yikes. I guess you missed that part of my post that said to review the pics and zoom in to make sure your subject was in focus. Most likely the AF/MF button was left on manual focus. It's also very important to select an AF point as well. When I first took a shot with my XSi, I left it in green box auto and all AF points. The camera selected the closest thing in the frame to focus on. This ruined a few shots. If I had thought to zoom in, I would have seen that the focus was incorrect.
