Been quite a while since posting in the thread, but I have been following along what you all have been posting.
Thought I had lost my 200 and 300 early December when they stopped autofocusing. Took them out to clean them as I was thinking about sending them in for repair, and thought I'd try them again. The 200 woke right up. The 300 took a little coaxing. Both working again. Only thing I can think of is the cold stiffened the internals up a bit (grease?), and now that it's getting warm... Anywhos.
My Pentax tele lenses are working, starting to get bird photos. Happy days.
K-1 + DA*300, heavy crop (6mp) and resize for web, Rufous-winged Sparrow (I think) a couple days ago.
