I am concerned about the focus on my brand new K-7. it came supplied with two kit lens - 18-55mm and 55mm-200mm. Neither of them seem to have pin sharp focus. I have been testing the 18-55mm by photographing a wall with a window frame, so there should be reasonable contrast for the AF to latch onto. The autofocus is softer than the manual focus, but I cant get sharp focus manually either.
I have attached a couple of pictures for anyone to comment on, to see if I am expecting too much. They are from the 100% RAW file, opened and cropped in Irfanview. Both were shot at 24mm f56, ISO100, no sharpening or anything else, as far as I know.
Any thoughts?
