DM> I'm not saying I know this to be true, but rather pose this as a question. It pretty much does so, provided the slave flash doesn't overexpose the main subject. When in a hurry, I set the 360FGZ in auto mode on one stop wider aperture than the one on camera to make sure it provides half of the necessary light at most. For careful setups I prefer the manually adjusted output based on aperture, distance, light loss on bouncing and how important the slave is in the combination. Even if it works quite well - still I see the need for a full wireless P-TTL. Servus, Alin
