No sane person will ask for a repair or exchange for 30sec exposure with only 1 hotpixel. Man my DS originally had 10+ hot pixels and came back with 10+ hotpixels at just different positions after Pentax Japan replaced the whole board. I know they did because the exif data shows a different set of serial datas. I just shoot RAW and forget about it.

Are you sure?... Dark frame subtraction requires an exposure with the shutter closed, and then a merging of the two images to remove spurious pixels.
That's exactly how the noise reduction in all Pentax dSLRs work!

Yes, he is sure and he is right. "Noise reduction" in K10D menu is for dark frame subtraction and is activated only in longer exposures (longer than two seconds if I am not mistaken).
Thank you! That makes a difference to me. I will use it when necessary. I'll study up some. I don't often use exposures that long, but with the new toy, ....
