Re: Enabling "Servo" mode on Metz 48 AF-1....

Thanks for the answer. I am such a novice with flash that I don't know whether I'll use this much or not. I can imagine wanting rear curtain flash once in a while, though, so I'll at least go ahead and update the firmware so that it's ready when I am.

This, by the way, is one reason to choose Metz over Sigma flashes. When I was shopping for a flash last year, the deciding factor for me was that Metz can be updated via the internet, whereas Sigma has to be mailed into a service center for a free update. Not sure if that's still the case with Sigma, but now I'm glad I chose the Metz for that reason.

Thanks for the info!

I just re-read your question, and after some more tests, I realize my error. Anyway, I did some more test shots, but was more careful about reflective surfaces.

Indeed, the built-in flash set as "Controller" in Wireless mode does not contribute to the exposure, but it does trigger the Metz flash in Servo mode, although only at a power setting lower than 1/2.

There is something far more complex at work here than I can easily describe, considering how there is a cut-off point with Rear Curtain Shutter Sync speed and the power output threshold of the flash with Controller mode.

Maybe someday I'll have the patience to sit down and create a table with all the various permutations between camera and flash settings.
