Hi David, Some years ago by the time the 5N was just released, a well known and appreciated pdml member - Roberto Burgos (who unfortunately has left the group for some time now) conducted a formal test of the MZ-5N flash compensation under controlled conditions ( flashmeter, studio, camera loaded with film). He found out that the flash compensation was handled quite precisely, except for the -0.5 EV and +0.5 EV compensations where the flash output only changed with -30% and +30%. Also according to his observations, the compensation changes the ambient light exposure as well, except for the manual mode. His findings were later confirmed by others including myself (in a less scientific manner - guessing from slides ;o) ). Back to your tests, you seem to have scooped a significant change in compensation implementation between the MZ-5N and the MZ-S. While the MZ-5N compensation affects both flash output and ambient light exposure in auto modes (and this is a well established fact), the MZ-S applies compensation only to the flash. Well, this must be a great news for the MZ-S owners having long complained about the lack of dedicated flash compensation control, just as it was for the 5N owners finding out they can still do flash compensation with their old-style, minimal controls camera. As for Pentax not publishing the complete capabilities of their products, not to mention advertising them... well, this is a story just as old as this list. From the cultural fracture between the development and marketing departments to the plain idiocy of the Pentax marketing, it all have been beaten to death. With no change from Pentax part. :o( Servus, Alin
