Originally posted by Syb Metz Flash 32mz3 has three auto-modes, a TTL setting and a manual setting. I would like to use this flash as a secondary (slave) light source, set on a SCA301 and mecalux 11 slave unit. But does auto-mode work well for you? I have done some quick tests yesterday and found it to be far over-exposing.
It seems that the 54MZ3 stops when sufficient light has been reflected from the subject to the flash's sensor. The 32MZ3 should have this feature too, but does not get this exposure correctly.
Syb, the 32 MZ-3 should work fine in auto mode. It does expose too much with direct flash (non-bounced) nearby, but otherwise it's usually spot-on.
Maybe there is a difference in the "scope" of the auto-sensor (e.g. the width)?
I don't know about the combination with the SCA301, but there are a few dpreview threads from 2007 that describe various combinations of the Metz flashes with MZ-sockets. Maybe you can check these. See e.g.
