I had two holidays when I shot in parallel on K-m (K-2000) and K200, and two holidays, when on K-m and K10.
I must say, the K10 has the weakest dynamic range (even in RAW), the worst ISO 800 and K10 is the slowest in operation.
K-m the best of the three. K200 in the middle, closer to K-m.

Originally posted by Jome one of the key feature for me is to be able to be able to do the SDM to screwdrive conversion (I'am lurking for a big update: an affordable 60-250).
To switch from SDM to a screwdriver, you need to program the lens itself. It does not depend on the camera model.
