So, who's going to be first?

btw, this hot pixel mapping- do you have to apply it on every single image? (doesn't sound right to me). I performed it once and then mistakenly took a picture with the lens cover on and had MANY hot pixels....

You should only have to apply it once initially and then maybe every few months if the sensor is prone to develop new hot pixels.

It's worth remembering this:

A great firmware update, but a few things:

2. If you do the hot-pixel mapping (Menu>Settings>Basic Setup>Dead Pixel Correction) and *then* initialize settings, it'll forget about the dead pixels. I made this mistake the first time and was disappointed to see that there were just as many dead pixels. Rerunning the pixel correction *after* initializing settings will fix this. However:

3. Dead pixel correction is a vast improvement, but far from perfect. In JPEG mode, I have about six hot pixels now (three of them non-obvious), whereas I had upwards of 20 or 30 before (too many to bother counting). It's a big step, but still not as good as a hot-pixel-free DSLR.

The fact that initializing settings causes the pixel mapping to be lost could indicate it's stored in RAM and not NVRAM. If that's the case leaving the battery out for a long time would also cause the information to be lost.

When the camera maps out pixels it takes a dark exposure to identify the bad ones. Only those detectable within that exposure time will be mapped. Those that would appear with longer exposure times/higher temperatures will not be counted. Judging by how fast the mapping takes place the dark frame exposure cannot be more than about 1/2 sec. We don't know how bright a bad pixel has to be for it to be counted. Due to the variations in exposure time, temperature and detection threshold I'm not suprised that some remain.
