k-r underexposing 4 stops

pikoli · 07-06-2013, 06:53 AM

I have a weird problem with my K-R:

sometimes literally every other image is 4 stops underexposed which is a lot! It is annoying as hell!

And sometimes you can get 100 images spot on. What could be the problem? I have no idea..

cheers

May be the lens rather than the camera. That could be sticking aperture blades. What lens are you using and does the issue occur with multiple lenses?

Thats too bad.
Make sure you don't have bracketing enabled, you don't have hdr (or other scene modes) turned on, and that you don't have exposure compensation, as any of these might cause your images to have +/- exposures.
And yes, its great if you can try another lens.

Then there is the usual method:
-try different battery, charge it up, let it sit outside the camera overnight
-reset to factory defaults in the menu
-clean the lens contacts, camera mount
-update firmware

Beyond that, try looking at the meter closely, is it stable, or does it keep changing even if the scene remains the same? What about in live view, is it better?
