Yes, you can do the 2nd curtain with the Metz, but most of the time I just drop the shutter speed to get the background to register. You will need the correct Metz module, which is 3401, and that unit has the Man/Sun adjustment such as the SB 24/26, which I never use. I do use the exposure compensation a lot, which on the module, is a small slider switch in 1/3 increments, extremely fast and intuitive to use especially at weddings. When shooting fast and switching from light colored bridesmaids dresses to black groomsmens tuxes the adjustment is quick by FEEL and Doesn't Require My Eyes, which means I can pay attention to what is happening and not on the exposure compensation adjustment. All other flashes require a LCD screen look, multi-button press and visual confirm, PITA after the Metz. Don't these people use these things?
