An irregular small but noticeable slightly dull spot is appearing with pictures taken with the sky in the upper (1/3) left background. It was more noticeable with gray and cloudy sky than with blue, but now will show up in both. Does not show up otherwise, but when it does always in the same place and under the circumstances described above (I see it every time now). Seems to be getting worse but maybe because I am just now noticing it. I cleaned the front lens and used a lens cleaning cloth on the back lens . I also did the K200D auto mapping of defective pixels but nothing helped. Very annoying in the shots it appears now that I see it.
My camera (from Amazon) is new (had about 14 days), but I sent in the rebate form with the UPC cut out from the box before I noticed the spot in a couple of newer pictures. I have owned a few p&s digitals (Kodak and Canon) plus a couple of film SLRs (Minolta and Canon) and never had any problems, so guess I did not check out the Pentax closely enough when I first got it. Any suggestions other than send the camera and/or lens to Pentax. Looks like I got a defective camera or lens.
Thanks for any suggestions.
