What are some flash triggers that allow for manual power control from the flash trigger itself. No TTL. Yongnuo 560 flash with Yongnuo 560 tx trigger Godox 850 flash with Godox ft16s trigger Cactus rf60 flash with Cactus v6 trigger Nissin di700 flash with Nissin Air Commander trigger Are there any more than these? I'm new when it comes to flash photography, but I have been using a pair of Nissin Di466's with a cheap radio trigger. It works perfect BUT everytime I want to adjust the flash output I have to go to the flash itself to adjust it which has become annoying. I'd like to upgrade, but not sure if its worth it. I don't do flash photography often one reason having to go to the flash to adjust power. I know there is a RC mode for olympus/lumix but it requires line of site which can be problematic.
