Except for the fact that the only major break in features is between K and A lenses (M lenses are K lenses, there is no mount/operation difference except on the late M 28/2.8 which features the A's linear aperture as it is an A lens with a plain K mount and aperture ring introduced only because they ran out of parts early for the original M version and weren't ready to launch the A series yet).
F and FA lenses add incremental improvements to the K mount (AF and active communication between lens and body), but it's the move to linear apertures and aperture communication with the A lenses that presents the capability break. If you don't understand why these features are important to camera design, you aren't likely to understand why Pentax made the break there and not at the K/M42 split. -Adam J. C.
