I just bought a Metz 48 AF-1 to use with my G1. I am not much of a fan of on-camera flash, but occasionally I will bounce off a ceiling to illuminate a room. With the current software, both the 48 and the 50 offer a "dumb slave" mode where they fire when they see another flash. This is exactly what I want for bounce; I'll put the flash on a table, for example, pointed at the ceiling. But, I have a weird problem. Setting the 48 to dumb slave mode works fine and it fires when the on-camera flash or another flash fires in the room. But none of the Metz's light ends up in the photo. It appears that the Metz flash is delayed enough from the sensed flash that the G1's shutter is closed when it finally fires. I have tried different modes, etc. and nothing I have tried solves the problem. Has anyone else seen this? Any suggestions?
