I bought a 2nd hand 70-300D ED. But something doesn't feel right.
First, the focus ring feels damped, as tight as the zoom ring. I think the focus ring should be very loose.
Second, photos at 300mm f/5.6 look very soft. The camera was on very stable tripod. It's soft that It looks as if the camera were hand-held at 1/10s....
Are these normal? Or I got a bad copy? I have a feeling it's the latter.
