[QUOTE="philz, post: 174351, member: 15587"] Happy Sunday morning fellow Nikonites! I was given a Nikkor AF 35-70mm f/1.33-4.5 the other day and have been playing with it on my D3100. The person who gave it to me said that she had gotten it as part of the package when she purchased her D50 and that the AF no longer worked, and that she was going to purchase a new lens anyway. Put it on my camera, fit beautifully. Used manual focus ring, focuses crisply. Used zoom, small problem I'll ask about in a minute. As regards the AF, is it reasonable for me to assume that this lens, mounted to my D3100, and assuming the mechanics of the lens plus the electronics *should* allow the AF to work ... or am I hoping for something that's not in the design? If it *should* work, does the clean the contacts comments above seem likely to be a possible solution ... stressing possible? Second question ... I've noticed that I leave the lens focused to the infinity mark, the manual zoom gets INCREDIBLY stiff and actually freezes ... I have to refocus to anywhere between the 5ft mark and down into the macro range. Obviously this is no big deal ... doesn't render the lens unusable ... takes a second or three for this old brain to reconnect a neuron and remember that this doesn't mean bye bye lens just move the dang focus! But it *would* be nice if all worked properly, right? So, even if the autofocus stuff I mentioned the first question can't work, for whatever reason ... and ideas on what might cause the zoom lockup when the focus is left on infinity? Thanks ... and happy Nikoning! [/QUOTE]
