I have a chance of getting a 75-300mm USM lens for $33...but....
the USM hiccups/stutters as it rotates....
Any easy solutions...other than manual focus, which does work fine....
i.e. it's the motor, not the barrel, that's not smooth...at that price I should get it anyway, but even my gear lust has limits....maybe...
Thanks....
