Some *istD questions

[Paul Stenquist]

I know that the *istD has a raw file option. Does the PhotoShop CS 
(PS8) RAW converter support the Pentax files? I assume Pentax has a RAW 
converter. Does it offer different file size options? Is the Pentax 
sensor a CMOS or a CCD? I'm sure all these topics have been covered 
here, but I wasn't interested until the K lens compatibility came 
along.
