Pentax makes a point of marketing the fact that you can use almost any
lens they've ever sold on their DSLRs. With various adapters you can
use M42 screw mount, K, KA (has the A position on the aperture ring),
KAF, KAF2, and the "crippled" (no stop down indicator in the mount, so
the lens needs the A position) versions of KAF, 645, 645AF, and 67
lenses. Even with the lenses that don't have the A position the body
can be made to stop down and take a meter reading.
