In short my K10 AF might be breaking and I have a lens on now where it works but if I switch lenses it may never come back
Has anyone had a similar problem? Know how to avoid or fix it? Please help;
The story:
I've been on vacation with the K10 and too many lenses, quite often ripping lenses off and slamming lenses on to the camera in a hurry, and took one fall on a trail where the end of a long lens took a knock on a rock (which could have torqued the bayonet mount I guess).
Two days ago I put on my 17-70 Sigma, went to focus and was greeted with the
sound of the focus drive motor in the body spinning crazily, but the lens was not engaged and would not focus.
Concerned it was a software glitch or something I rebooted the camera, removed and replaced the lens. That time the problem went away and the lens' focussing worked.
A little later (and after doing a lot of catch-in-focus shots with another lens) I had the same problem again, but this time no amount of cycling power and putting the lens on and off, or trying other AF lenses, fixed the problem. GAH!
I looked at the mounting ring assembly on the body of my camera,
and wiggled the small squarish metal tab which can be found on the inside a few degrees counter-clockwise from the red dot. Mine is a bit scratched and bent (but not much) compared to other k-mount plates. I tried to push it back flat-ish. This did not fix the camera.
I took my finger nail and ran it up under the leaf spring beside the metal tab (changing nothing as far as I know), and poked at tab once more. This seems to have fixed the problem for now.
I am afraid to switch lenses atm however, lest I lose my AF drive.
Anybody experienced this before? basically the AF coupler may or may not engage depending on how you hold your mouth when you do it.
Is that little square tab near the red dot the culprit?
Any help much appreciated.
