I have a K100D with a pentamirror, and K20D, K5 and K3II with pentaprisms, and with identical lenses on, I cannot tell the difference.
Interesting. My own experience was that the K100D (and super) were darker in the finder than the K-50 or K-3. Try a slower lens to see if this is revealed and then try a faster one. I don't recall which condition made it more obvious but I can try myself again later.
