Any advice on how to fix slack in AF 35-70 2.8?

[Bruno Schroder]

I have a AF 35-70 2.8 which has developed enough slack to stop the AF screw engaging in the camera. Has anyone opened this lens? Any advice to fix it?

Thanks.

I'm going to have nightmares about this (or at the least pipedreams).

I wonder if I should open my AF 35-70/2.8D and try to fix its decentering problem. As a kid I used to take apart my toys but never bothered to put them back together. I was probably a cockatoo in a previous life.

I have to admit that this diagram is indeed a bit scary

Always loved these hand drawn explosion pictures. They used to have an entire department doing it... now it's all digital.

Lost art indeed
