K-50 - focus mode stuck in manual

I have a K-50 which is approximately 3 years old. A few months ago I experienced the aperture block issue, which is well documented here. Fortunately I was able to open up the camera and repair that myself.

Soon after that (perhaps 1-2 weeks), the autofocus on the camera stopped working. Although the dial on the exterior of the camera is set to AF.S, the camera is stuck in manual focus mode. When I remove the lens, I can see that the screw which drives the autofocus is depressed in the interior lens ring. The exterior dial is also stuck on either the the AF.S or C setting - I cannot rotate it to the MF setting (well maybe I can, but I don't want to force any harder than I have already tried).

Is this an issue anyone has ever come across? Is there a simple fix for this? I've tried fully charging the battery, using three different lenses. I also can't find any threads documenting the same issue.

Any help would be much appreciated. Although I can still take pictures , having to manually focus all the time is not ideal.

Welcome to the Pentax Forums!

I don't recall a problem such as you describe, though it sounds like there is a mechanical jam of some sort. Is there any chance this might be related to your self-repair effort?

I would speculate that the AF dial on the body wasn't lined up properly with the switch on the chassis. Then it slipped out completely into a position where it jammed. Opening the case again and checking the switch positions seems like a reasonable option to me.

I had a similar problem to this in an old *ist DL. I fixed it by opening the body and the pin fell back into place. Reassembled and it is now fine.

Same issue on K5

I had exact same issue on my K5 shortly after replacing the lens release button - camera registering manual focus, af button stuck on af-s. It happened on day 2 of a 5 week tour of Iceland & Greenland so was a tad inconvenient as I had to wait until I got home to make the fix. Figuring that I hadn't got the af lever positioned properly on reassembling the camera, I took the camera apart and lifted the front off just enough until I could easily move the af button - luckily I didn't have to completely remove the front as I wasn't looking forward to fiddling with the lens release button spring again! Then replaced the front & rest of body, testing the af button at each stage to make sure it was working properly. That was 3 months ago & camera working fine after another thousand shots or so since. Hope this helps.

Focus dial problem on my K30

"I would speculate that the AF dial on the body wasn't lined up properly with the switch on the chassis. Then it slipped out completely into a position where it jammed. Opening the case again and checking the switch positions seems like a reasonable option to me"

I think I have the same problem with my K30. The focus mode is stuck on M , even if the switch is on AF. I took of the kit WR lens and than put it back and the focus works until I move the switch focus to manual mode. The mode remains on manual after that. I think its a mechanical problem, but maybe I can rezolve it, and not to be forced to go on service shop. Thnks

Can you be more specific?
