Today I tried to use filter effects with flash, but I could not get the flash to fire. I tried setting the filter effects from both the main menu and the artist pallet on the dial. I wanted to try some of the softer filters for snaps of older family members. Outside with no flash I thought the silky monochrome looked ok, but no go with flash. I was just trying TTL with a metz 26 AF-2. Any ideas what I have have done wrong, I tried all the modes, and the flash works fine with the filters turned on. Flash is set to "forced flash on"
