Originally posted by deejjjaaaa The K20D was positioned by Pentax as advanced DSLR, the K10D was positioned by Pentax as Popular class DSLR, so the K20D was already one step up from the K10D, the direct replacement for the K10D was actually the K200D because K200D is in popular class - same class as the K10D was targeting.
K-7, however, is on the top of APS-C cameras, semi-pro/pro class. This is above the K20D class.
D200 and D300 were both in the same class. But the K10D -> K20D -> K-7 development means a change of the class. Or to put it easier: D200 = D300. K-7 > K20D > K10D. K200D = K10D.
