K-50 Help - Metering is leading to pitch black photos

I took my camera out today for some photo-making after a month or so. I took a photograph in aperture priority mode and it came out almost pitch black. It seemed to be metering correctly through the OVF - so a bright day should have been fine with f/8.0 at 1/100s shutter speed, with an ISO of 400-800.

Note - this issue occurred both with my 18-55 and my 55-200.

I was able to get photos to come out via live view, but I had to bump the ISO way high, keep the lens wide open, and slow the shutter. This seems to indicate a sensor metering issue, but I don't know where to start. My google-fu is weak on this issue.

Thoughts? What questions should I be asking?

I'll upload some photos later with examples of what's going on.

are you holding the camera at eye level or on a tripod. Maybe your issue is stray light coming in through the eyepiece

It has occurred both when i'm using tripod, hand-holding freely, and pressing it against my face. I'm pretty sure it's the dreaded K-30/K-50 aperture issue at this point since the problem only occurs with auto- lenses.

Hi, I am having the exact same issue you experienced with my K-50. Have you been able to fix the problem? Thank you
