I need to find out more about this, because it doesn't work for me. At least, not with the lens I use.
I'll admit it's not your normal A lens, but this set up worked on the MZ-S and the *istD and I'd love to have it work on the K7 (or the next camera upgrade). I have added A contacts to a set of bellows. With the camera set to fully open aperture (f2 in this case), and the lens on the bellows closed down when the prefire happens, the camera calculates the correct exposure and the flash fires correctly - using the *istD and 2 AF360 flashes. The K10D and K7 fire the flash at full output. Both the newer cameras behave as if there is an A lens connected to the camera. The camera recognises the aperture range I set the mount to and I can select the aperture accordingly. It even meters correctly for changes in the aperture set on the camera in P mode. Everything except the flash output. If someone has a simple A lens (maximum of 6 contacts on the lens), a K7 and an AF360 flash can you conduct an experiment to see if you get correct P-TTL exposure out of the setup? That will at least let me know if it's just me or a design issue. I'll have to try high speed sync mode to see if that makes a difference since it works for Paul.
