I've been shooting the Canon G series in RAW for a long time. It's actually why I went that route.
Pentax did have a camera that had a hack (A40 maybe) to allow you to shoot RAW. However, it reset each time the camera was turned off, making it virtually useless.
These cameras can shoot RAW, Pentax just chooses not to enable it. My guess is most people shooting these don't understand RAW and it would be a headache for customer support, and user reviews.
G series, Nikon upper ends shot RAW, some Panasonics, and some upper end Ricohs, I thinka few older fujis did as well. Not much else in the compact end. There were some bigger camera (Minolta A1/2) that shot RAW but those are SLR size!
Originally posted by impete82 was at the photo show this weekend, and saw the Panasonic LX3 and was absolutely floored there were P&S's which had RAW. if i had the funds, i would be all over that camera. would be so nice to have RAW capability when going somewhere a huge camera bag isn't so ideal. i then went over to the Pentax booth and asked if Pentax would ever make a RAW p&s, but they didn't seem happy about my question. maybe it was a long day? lol
