I read your reports which intimates categorically that the problem is systematic and affects ALL k5's.

Then I take a k5 turn the lights down really low and take shot after shot pin sharp.
How do you explain the discrepancy of real world and your lab results.? "


Probably You used "long" lenses for a photo? My camera is almost ok with 50 mm (very slight ff in lo ligt), but heavilly ff with lenses set to wide (tested with 50 f2,8 macro and DA 16-50). Please test your body with wide lenses. I am interested to hear the results from You.

Phase detect

contrast detect

As expected on this new body (self uncalibrated) phase detect is sharp and accurate.
Contrast detect took nearly 1.5 secs to achieve lock.
