Originally posted by Edvinas while I don't think that K10D needs to be updated, I agree with RiceHigh regarding K100D/K110D. New SDM lenses automatically makes those bodies obsolete. Pentax should bring out entry level body with SDM support as soon as possible.
I have a very similar view as yours, except that I think the K10D shall have an enhanced version whereas the K100 should be replaced, that's why I suggested there should be a "K10Dn" and a "K200D" in the OT.
I just list out some of the problems of the existing K100D and K10D below:
K100D: No SDM support, No DR function, Rechargeable Battery Problem, Auto ISO Bug, 6M Pixel only, Not Compact as Nikon and Canon's entry level DSLRs
K10D: Blurry Jpeg, Ineffective DR, Outdated and Inaccurate Metering System, Bulky and Heavy, AF Problems, Noisy Pics from ISO 400.
