The auto-focus on my lens seems to be noisier and slower in the past couple of days. I actually thought something was wrong as it wasnt locking focus properly sometimes. I dont have any other AF lenses to try. I have tried a few FD lenses with adaptor. Could the adaptor affect the connectors? Id think then it would not work at all if it was the camera body... just thinking. Anyone else had issues with the kit lens? Its a couple of months old, but I pretty much baby the thing. There is a lot of movement (play) in the lens segments when extended but I thought that was just normal for this lens. Any thoughts or recommendations?
