Originally posted by Deiberson I've been dealing with focus issues since I've been with Pentax. K-10, K-x and now the K5...
Is there a "lens adjustment" setting that compensates for this? If so please explain what it does and how it works in detail. I am unfamiliar.
Is your K-5 is consistently front focusing? If so, it sounds like a calibration problem.
The K-5's AF adjustment is on page 4 of the Custom Setting Menu, item number 26, AF Fine Adjustment.
I like the moire pattern AF adjustment method, which is explained
here, but just taking a series of shots of a flat object while varying the AF adjustment works OK too. (Between each test shot, defocus the lens.)
That you've had trouble with other Pentax cameras is strange. I had a K-10D, and it did not misfocus. Also, my K-5 focuses accurately, although with occasional misses.
A couple of other observations: Your sample shot was taken in good light according to the EXIF, so a low-light AF problem is not the issue. Also, if the K-5's relatively large AF frame was the cause, the bowl edge near the baby's eye, or the background just behind the baby would have been in focus.
