It's not a matter of doing something dodgy, it's a matter of not being privy to the infromation that the engineers inside Pentax have when they design a camera or flash: The designers of the K10D they had access to the actual code used in the AF360FGZ, so they could guarantee compatibility. This kind of thing is particularly tricky when working with something like digital communication between a flash and a camera body. As far as I know, no one besides Sigma has even tried to make P-TTL-compatible flashes for Pentax, probably for precisely this reason. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
