Nighthawk,

I owned a Pentax iSDs. I was a great camera, until I dropped it 5 feet onto some rocks. I just replaced it with a K110D. I can tell you that the Pentax lens compatability is amazing. I have several K mount lenses that work perfectly. Even the old Pentax screw mount lens with K adapter works well with the new digital.

Just don't drop the thing. Digitals don't seem to take impact like the old Spotmatic or MX film cameras!
