One of the reason I got the K20 was the internal pixel mapping function, but I can not believe that a brand new camera would have been sent out with so many stuck/dead pixels.
How many K20d owners had to map dead pixels when you first got the camera?
I am trying not to be a negative ned here, and I know there are millions and millions of pixels.
Also can anyone tell me how to tell how find how many shutter actuations are on the camera? I have seen it mention here before but I cant find it in the search now.
If I am doing astrophotography with my K20D, I can bet on there being about 5 hot pixels showing up. If dark frame subtraction somehow misses them, I just clone them out in post-processing. I occasionally get about 3 hot pixels showing up in exposures up to 10 seconds but they are not consistent.
As for shutter actuation count, it is visible in programs such as Photo Me for the Windows platform or exiftool for linux. Not sure about Mac software.
