Got my (second, cause I sold the other one) FA 80-320 today. Hooked it to the camera, and nothing. Of course, it's over 60 degrees and the robins are returning today and my new lens isn't working right :ugh:
Symptoms:
-No aperture control (F--)
-No AF (wonder if the whole lens is dead?)
-No focal length recognition
-A position locks fine
-Aperture works fine as an M lens
Troubleshooting:
-Wiggle the lens in the mount
-Cleaned contacts (lens and camera) with 91% Iso alcohol
-Moved aperture ring in an out of A position
-Mount/dismount lens multiple times
-Tried my only other A lens, the (working) PKA Adaptall. Recognizes aperture perfectly
-Open circuit between pin 3 and lens mount (indicates a bad/dirty A switch inside the lens)
-Eric at pentaxs.com doesn't have parts
I haven't contacted the seller yet. I'd rather have the lens working than send it back...he'll probably tell me to pound sand anyway...ebay doesn't roll that way anymore, however, so I'd rather fix it or get a partial refund. It's the AF issue which concerns me most, because something must be royally wrong inside it.
Can someone tell me if these contacts look right? I don't have any lenses newer than Ms at the moment. Notice the two stick up, while the other 3 do not.
