I purchased a Pentax K10D about a year and a half ago. Worked fine for me until late April of this year. At that time, it began to freeze intermittently for no rhyme or reason. I could take the batteries out and reset it, then take X number of pictures (anywhere from 3 to 50 in some cases) and then it would freeze. Sent it in to Pentax since it was still under manufacturers warranty. Pentax sent it back to me and it appeared to work just fine...until this last week. My wife and I were vacationing in Florida, and it began to do the same thing. Froze on me right as I was taking a picture of the Cape Canaveral Lighthouse, which is nearly impossible to get to. I have a Circuit City extended warranty that I purchased and am getting ready to send it back to them for work. My concern is that it's going to keep doing this. Plus, if it happens to work fine for those x number of pics, as it will do from time to time, for United Camera (where the work is to be done on it) will they do anything at all? When it works right, it does everything I need. But if it's going to freeze at any given moment for whatever reason, it's of no use to me. Have any of you had a problem along these lines and if so, how did you remedy it? Thank you for any advice you can give.
