I occasionally noticed dust in the finder of my MZ-5n, and once mentioned it while I was at Pentax Canada to buy a filter or something. The parts manager called the head technician, who took away the camera and returned it within five minutes with the focusing screen cleaned. He said I shouldn't try it at home, but it's probably not that complicated.
As for the MZ-S, I haven't seen any dust in it yet, and anyway, the focusing screen is "user-removable", so I'm not worried about it. Pat White - This message is from the Pentax-Discuss Mail List.
