When I was shooting with my pfa-50/1.4 tonight, there were several times that the camera shot in af-c mode without refocusing, when I expected it to refocus.
A lot of the shots with that lens seem to be way out of focus. Are any lenses particularly prone to tricking the camera into thinking that they are in focus, when they actually aren't? I don't seem to have this problem on other lenses. It doesn't seem to be a motion blur issue. I was shooting tonight, in raw, in several modes of high iso noise reduction at ISO 3200. At first glance it doesn't seem to make any difference, though I'll still have to test more scientifically. I got a call from Mark Davis at Pentax today to discuss my issues. Without looking at my pictures he seemed to think that my camera sounded like it was performing nominally. After the conversation, I emailed him the links, with explanations, to my various test sets, but I haven't heard back. A lot of frustrating things may be happening with my camera, many of them quite likely my doing, but I must commend Pentax, and especially John C, because they seem to be making every reasonable, and perhaps even some more than reasonable, effort to resolve the issue. On the bright side, I seem to be learning a lot about my camera. -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
