Hi, I have a 28-70 it look very similar, and I know are similarly build, so I have a question and maybe you can help me... I have my lens try in a manual focus fil camera and my d3100 which lack of motor drive for focus so i have never try the autofocus on the lens, and something funny happens when the focus barrel is all the way to infinity, the zoom get stock at about 50, if I move the focus right to the infinity position I can keep moving the zoom. have you experimented this with yours? thx
