Thanks for responding, Boris, Bob S. and Steven L. After testing all my lenses, I suspected there was a problem with the FA 50/1.4, not the camera. The results with my other lenses were from excellent to damn good, including the 31 ltd. where I thought I saw the problem first.
Today I got the opportunity to test-shoot with another FA 50/1.4, and the difference was astonishing. Mine has been delivered to Pentax Norway for recalibration, and the K10D is definately out of suspicion.
