I purchased the Flex, Mini and the AC3 for my Canon mkIII and 580EXII speedlight. Everything works great in ETTL mode but I need manual mode! I have spent 2 days trying to get the AC3 to adjust the flash power but no matter what I try it just fires full blast.
I have reset the mini and flex to factory settings, updated firmware, set channels in the PW utility.....so spent with this whole process.
Any ideas? Or should I just scrap them and buy something that is dependable? IT SHOULDN'T BE THIS HARD
Thx
