I'm not sure how or when this issue popped up, but my Pentax K3-II can't focus correctly anymore. I tried on both my lenses and encountered the same issue:
DA* 16-50mm
DA* 50-135mm
Following
advice elsewhere on Pentax Forums I adjusted the AF fine adjustment to +10, which almost has it right, however I've noticed that when shooting at f2.8 the picture seems hazy, especially towards the edges of the image. Even at f22 the image isn't completely clear. Here are a couple of sample shots:
DA* 16-50mm
f2.8 ISO100 - AF point at white dot with +10 AF fine adjustment

Is this something I can fix myself or a service centre job?
