I'm going to quote Cambridge in colour now link
Fixed pattern noise includes what are called "hot pixels," which are defined as such when a pixel's intensity far surpasses that of the ambient random noise fluctuations. Fixed pattern noise generally appears in very long exposures and is exacerbated by higher temperatures. Fixed pattern noise is unique in that it will show almost the same distribution of hot pixels if taken under the same conditions (temperature, length of exposure, ISO speed).
Most RAW programs of these days however already have algorithm in it to define hot pixels so they already get filtered out these days, DFS is not really needed any more.
However if you''re going to take photos of the night sky it will be better to make one Dark Frame to see where the fixed noise is and with a program you can get the noise out of all the exposures before you stack them.

The 135format issue for Pentax has been done to dead so no need to go over that again.
Will we count the cost of always wanting more
Never satisfied with what we had before

I tried to pan this shot, you've no idea how hard it is to do that with a shark.
Does anyone know of someone else trying, i wonder if they did better

A raw file please, and i would be interesting in your comparison.
What is your first impression of how the camera handle?

Thanks for the comments so far, I'm not sure about the Exodisc as I tend to use far to many different sized lenses, although the X-Right looks interesting. Any other suggestions.
And they have something called a Cube link
But if you want to be colour accurate, correct WB and exposure than the colour checker passport is the best all in one package.
For the rest I don't know of in products.
