My K-r seems to have focus problems with artificial lighting, even after confirming focus. My K20D doesn't show that kind of problems, but sometimes its focus is off even after confirmation. I haven't been able to pinpoint why - when I try the same shot the next day, it seems to work fine...
Thats what happens to me, I´m gonna try the focus adjustment, and see if it works better,,, I love that lens, but when I see the pictures blurred, I feel so disappointed.
