Hi Guys - thanks for your suggestions. The RAW/FX button didn't seem to make any difference. But by pressing buttons within the Camera Record [1] menu I somehow got to a different screen that I hadn't see before and setting that correctly appears to have cured the issue. Hope it stays that way. I know RAW is better but I mainly want simple images for my own use so JPEG works better for me. Thanks again.

My K-3 was set to capture JPEGS for general images.

However, partway through a recent museum visit it reverted to capturing in RAW.

Using the menu I am now unable to select JPEG as a capture mode. I can select JPEG 3* as the setting but the camera just reverts to RAW when exiting from the Menu.

Apart from this function - everything else appears to work normally.

Any suggestions please?

I have a black/chrome I-10 (as does another friend) and we are both having problems with images being badly over-exposed.

This seems to be erratic as some images are fine and then others not. It seems to get worse the longer the camera is left switched on - but that's a perception and havn't done controlled tests.

I am a fairly experienced photographer, always used Pentax (K1000, MX, ME, iST) but never come across something as erratic as this.

I have tried doing a Reset and looked at all other settings but getting to the point now where I don't trust the camera to get what I want.

Anybody have any suggestions?

Many thanks,

John
