Originally posted by cminer52 Wondering if anyone else has experienced this problem, had the crazy mirror which stopped after I took out the battery, restart was fine but after taking maybe a dozen images the camera switched to manual focus, no way to get back auto focus that I can find, message when turning camera on is input focal length, cleaned contacts on lens (pentax 100mm f2.8) and camera, no change, thoughts?
Check a different lens to determine if the fault is in the camera or lens.
Clean the contacts on both, and check to make sure all the contacts are present.
Verify that the camera is indeed in AF mode. Move the lever to MF and back to AF to make sure it is not stuck part way between.
Make sure the lens is in the 'A' position if it has an aperture ring.
