[QUOTE="BF Hammer, post: 776379, member: 48483"] What comes to my mind is the 70-300mm is no macro lens. Try backing away a couple of feet from that fish tank and try again? No focus limit switch on the lens I know of, so maybe not that. I like Brent's idea of testing lens on another DSLR to verify it is the lens itself. If this is an older example 70-300mm that uses the camera body autofocus motor through the screw-drive on the mount, it would be important to isolate that. [/QUOTE]
