I've owned my k10d for a couple of months now and it has been doing a brilliant job until now. Suddenly it has started overexposing all my shots by about +2ev. I've only tested in AV mode and the green mode but I'm assuming the result would be the same in all modes. I only have one lens which is a Pentax 18-250 so I can't tell if it's the camera, the lens or me to blame. Has anyone else seen a similar problem?
I've uploaded a couple of examples to flickr to show you the problem, unfortunately I've just taken these in my dimly lit living room so the overexposure isn't as noticeable as it is on a sunny day, the problem should still be pretty obvious though.
This is the exposure the camera thinks is a good idea.

This is with compensation set to -2ev

Any Ideas would be gratefully received.

Thanks for your thoughts. The metering is on pattern, if you click on more properties to the right of the photo you should get all the exif info. The problem occurs on all metering modes and ae lock isn't being activated. Unfortunately the effect is apparent on every subject I photograph, always about +2ev. I've been unable to check the aperture on the lens by depressing the lever because I'm at work, but I will have a look as soon as I get home.
Thanks again, I fear it may need a trip to the engineer.
