Newbie here, got a question to consult you all. I got a 2nd hand 350D recently and was trying to buy a 2nd hand 17-85mm lens for it. But when I tested the lens, the camera does not focus properly, it kept going in focus to out of focus repetitively, then eventually focusing on a blur image.
Would like to know if this means my camera has a problem or is it a problem with the lens? Or is it an incompatibility issue? I tried all different settings, different shooting modes, but I can't get a clear picture at all. Please advise if you have any ideas what could be wrong!
Thanks alot for your help!
