AF sensors off?

Does anyone know anyone who can fix AF sensors that might be off? I have a K20D that seems to get a bit wonky in AF hunting like crazy and giving up a lot of the time. It may not be worth it unless it is relatively inexpensive given that it is an older camera.

BTW, I did ask Eric, but he doesn't do this kind of stuff.

Thanks

You think the AF sensors might be dirty? Hmmm....never heard of such a thing, but who knows. Not sure if that is something I can do myself. Not even sure where they're located to clean them.

Eric suggested that they might be out of alignment. Not sure how to address that.

What he said. Dust and/or film may accumulate on the lens for the AF sensor.

The AF sensor is in the bottom of the mirror box and faces toward the rear of the camera. Cleaning and alignment would be part of a standard CLA on the camera.

If it means anything, it often works ok for a few minutes finding focus without issue, then gets wonky. Not sure if that adds any useful info.

How accessible are the sensors?

Hmmm....I put a HSM lens on it (motor in lens) and it works fine. It seems like the problem was with the screw drive driven ones so far. Anyone heard of the screw drive mechanism going wonky while still working otherwise? And, any ideas on if that can be reasonably fixed?


Thanks
