K5IIs broken?

Hi All,

Two weeks ago, I went to photograph some stars with friends. On site, I turned on the K5IIs, noticed the f/ and time changing on the screen wildly, but didn't stop. Instead, I took off the 16-50 lens, put an old 135mm manual on, changed to M and happily took pics.

Yesterday, we came back from a vacation to Italy. I had taken the K5IIs, but was unable to take pictures. Here's what it does:

When you switch it on with it set to anything but M, the time and f-stop numbers change between two states, and some other things on the screen change, too. I have filmed it, here it is on Youtube:

What I have tried, to no avail:
- Reset
- Cleaned the contacts on mount and lens
- Tried different lens (the 18-something that came with the K10D)
- Firmware update (1.05 to 1.07)
- Another reset, you never know

Has anyone seen this before? What's the verdict?

THanks!
Jan

Sounds like it could be a stuck button (maybe the AF/MF switch), or the mount is being shorted.

Does the same thing happen with no lens mounted?

Good call! If I take off the lens, all is normal, indeed.

There is a sort of "snap" noise when I set the AF/MF button on the camera from "MF" back to "C" while the pin comes out of the mount.

When I set it to MF and pop the lens back on, the "MF" in the display stops flashing, but the time, f-stop, ISO, and the matrix still do.

[edit]: with either the body or the lens set to MF, I can actually take pictures.

After checking the MF/AF switch, I tried the kit lens again (the 18-55), and it works.

That means the 16-50 is broken, I guess. AAAARRRRGGGHHHH!!!

I'd say it's possible that there's some problem with the switch. I believe there are other threads in which users have reported the same issue (after a lot of use).

Thanks, Adam, for the help and suggestions!

I don't know how I didn't notice before, but it is absolutely the lens. It must have dropped (even though I cannot remember having dropped it).

The good news is that the body is alright, I guess.

Let's hope that's the case! If the shaft was engaged when you dropped it, then it could have also affected the part on the body.

Ouch, indeed.

And it wouldn't make a difference with the 18-55, as it is a non-SDM, correct?

One time I tried to shoot and I did not have my lens fully screwed on. The full control was not there until I realized I had to screw the lens on just a bit more (until you hear the click distinctly). As soon as I had achieved full contact, both the camera and lens behaved normally.
