While there are many digital SLRs that are made to operate in all kinds of conditions, Ricoh Imaging is marketing the Pentax KP as a camera for all seasons.
The Pentax KP has a 24.3-MP APS-C CMOS sensor that is linked to the Prime IV image-processing system. There is no low-pass filter, which is being seen increasingly these days. The ISO range is 100 to an astounding 819,200. Whether the top of the range is a usable ISO will remain to be seen.
