Very interesting. I tried with both my K-7 cameras and the K20D, so I'm fairly sure it's not the camera. With the K-7 cameras I have tested 3 different flahes. My only A lens was the A*200/4 macro, so maybe that was the culprit. But it metered perfectly for ordinary exposures, so it seems a bit odd to me that it should fail to do P-TTL...
