In over 20 years. I have the 18-55 WR lens and went to use it today and it will not autofocus, manual focus is OK. It seems like the lens is not communicating with the camera.
When I first turn on the power, the camera asks for the focal length of the lens, regardless of the mode it is in.
It acts the same on 3 different bodies, K10D's. All other lenses are working like they should, so I have narrowed it down to this lens is faulty. It has not really seen a lot of use, but if I can salvage it, it would make me feel better.
I have cleaned the contacts with electrical cleaner, mounted and dismounted numerous times, and checked the tightness of the mounting screws on the lens, all is OK. Moving the screw drive on the lens does result in focus ring moving, so it is not disconnected or anything. Camera makes no attempt to move focusing mechanism with this lens, just shows MF at the bottom of viewfinder.
Any ideas or suggestions welcome. What to clean, lubricate, bang on, tap or which way to throw it,
I really would like for it to work again.
Thanks, Mike
