They probably just set the threshold for the slave high, so it wouldn't
be sensitive enough to be tripped by the pre-fire flashes (they are low
power flashes).

I'm surprised you just didn't try the 500FTZ on the MZ-S. Since the

I have done that, and I use the AF360 on the Pz-1p. But once you take out

flash. It's as good as you can get without and incident reading flash meter. BTW,
there are a number of situations where
