Well I bent the aperture lever back away using just my thumb with enough pressure so that now it doesn't visibly stick anymore. I also cleaned both lens and camera contacts with an eraser. End result? No change in behavior. Other information as I've experimented. If I leave the lens in a non-A setting, and remove it from the camera and put it back on, operation is fine. If I set the lens to the 'A' setting and remount it, the symptoms recur (darkish viewfinder and inability to focus). At this point if I go off of 'A' setting to manual aperture, it continues to NOT achieve focus at every aperture, until I reach the click between f/11 and f/8, at which times it focuses. It does this fairly consistently. If I immediately rotate the aperture ring from the click between f/8 and f/11, to a smaller aperture, f/22 for instance it again DOES NOT focus and the viewfinder is darkish. If I have the lens in 'A' when I mount it on the camera, immediately dial down to f/2.8, and then up through all the aperture settings including 'A' it focuses fine. So I'm guessing there is something electro-mechanical in nature going on with the aperture-ring? Also, I've never noticed this before, but when in non-A mode I don't see an aperture readout in the viewfinder or top-panel. Just --. May be that's normal and I never saw it before. Thanks. This may be going in for repair. Does anyone know if Pentax will still repair an FA 100/2.8 Macro?
