k10d: around 21k clicks. 3 pixels "hot" in RAW mode, seen only in the first few seconds the image is openned in camera RAW- disappear thereafter and never seen in final picture or in jpeg captures. This has been a non-issue for me with respect to the 18k or so images I have on my hard drive, and I only mention it for the sake of completeness. If I'm not mistaken, new digital cameras often have a few of these pixels which are electronically "mapped out" at the factory and do not effect quality. Some dust behind rear LCD.
