K10D vs K100D size comparison
Ned Bunnell have published 15 photos of Pentax K10D and K100D bodies side by side (plus two with Canon EOS 1D-MkII) in his blog. K10D a little wider and taller than his entry-level brother and a noticeably taller with D-BG2 battery grip. But look at it next to Canon’s pro-DSLR - K10D is not bulky at all.
