I had to return my first *ist D due to having many hot pixels. I noticed them in normal photographs such as this one: http://phred.org/~alex/pictures/pentax-istd/berries.jpg (warning: this is a very big image and a 3mp download). There are hot pixels everywhere and many of these showed up again in test photographs (even with fast shutter speeds) when using a black body cap instead of a lens. My new camera is much better behaved. alex
