On my PZ-1 with the KA ring, it seems to behave like any other KA lens -- in A mode (same as f/32 on the aperture ring), it "reads" the lens as an f2.5 maximum aperture lens and applies a program curve to it. It doesn't behave like an F lens (it won't give approximate aperture values if you're using the aperture ring to select f-stop and it doesn't give the camera focusing distance or focal length info).
The Adaptall KA rings have three contacts, I think, and one would be used solely for telling the camera whether the lens is in "A" mode or not. The KA Adaptall rings are all the same, though -- you don't pick one that matches the maximum aperture of your lens -- so the lens itself (Adaptall 2 ones, anyway) must communicate that info through the contacts on the ring.
I don't have enough test images back yet to evaluate the lens' performance.

Hi,
Sorry, so you use K adaptall with new bodies without problems. I think about KA ones.

I have the K Adaptall, not the KA. It works fine on my two newer bodies. No jamming. Meters as if it were a K or an M lens (no contacts on the mount).TTYL, DougF KG4LMZ
