Chinon CP-9AFautofocus lens, Pentax digital SLR compatibilty

I have all three of the K mount program cameras and the slimed down versions, Chinon CP-5, Pentax Super Program, Program Plus and Ricoh XR-P and KR-30sp. The XR-P, still uses the old fashioned shutter speed dial which would make it my favorite of the era; The KR-30Sp was the camera I bought as a graduation present to myself but, the Ricoh electronics are no longer reliable after 30 years (I have had several Ricoh bodies, just die in the middle of a roll). The Super Program is the flashiest and has the best build quality, But the CP-5, even with its plasticy feel. is the Program K mount that I use most often, I like the battery grip with AAA batteries or AA in the winder. and its very easy to use interface, and viewfinder info. And they just keep working. And the CP-7m is almost like a manual focus version of the CP-9AF and is also a great camera better than the A3000
The CP-9AF is one of those strange early dead ends, A simular situation is the Yashica 230AF, its a great camera, I like it alot, but you basicly have a choice of two lenes.

The CP 9 is an orphan camera as very few lenses were made for it and according to the Manual it only works in Program with KA amd CAF lenes.

Generic, RK, K and M lenses do work in Program mode on the CP 5 and CP 7 hence there are no P or A Chinon lenses, but both those camera have P mode. And the Sears KSX-P is labeled Dual 2 Program.

This is from the CP7m manual:
Programmed AE Signal and Aperture Setting

Unlike other program cameras, the CP-7m functions perfectly with "K" (even "KA" or "RK") mount lenses even in program mode. Generally, you
should set the aperture at its minimum seeing. Although you can take a perfectly exposed picture at any aperture setting, the applicable
programmed range is limited. The program AE signal LED is useful to check the lens aperture seeing for program modes. The programmed AE
viewfinder LED for P. PA or PC in use will "flicker" when the lens aperture is within four stops of the full maximum aperture. Set the aperture
within the range so that the programmed AE signal LED will not "flicker". On the other hand, if you would not stop down any further than a
particular f/stop, simply set the aperture ring to the desired aperture.
I have a K 3.5 28 on my CP-5 right now and Program mode works perfectly

So it looks like Chinon took a backwards step when designing the CP-9AF

As a Chinon Cp-7, CP-5 and KSX-P user, I can attest that any K-mount lens, Pentax M, Pentax A, or Ricoh P, etc. does infact work in Program mode on the CP series and Sears KSX-P, you just have to set the lens apature at the Minimum IE f16 or f22, you can also set it to a lower number if your situation requires less depth of field.
This is the one area where Chinon got the better solution compaired to Pentax and Ricoh.
