I'm having a hard time figuring out how to expand my flash system which is currently very modest - it only consists of Canon 430EX III-RT flash.
I'm planning to buy 2 Yongnuo YN-560 IV flashes and some receivers/transmitters. The question is: which receivers/transmitters do I need to control the power and fire all 3 flashes off-camera at the same time?
I spend some time investigating the differences between devices and I think I should consider some of these:
- Yongnuo YN560-TX (can control and fire YN-560 IV but cannot fire 430EX III-RT?)
- Yongnuo YN560-TX II (can control and fire YN-560 IV but cannot fire 430EX III-RT?)
- Yongnuo RF-602 (cannot be used to change power)
- Yongnuo RF-603 (does not support groups, cannot be used to change power)
- Yongnuo RF-605 (cannot be used to change power)
- Yongnuo YN-E3-RT (can control and fire 430EX III-RT but cannot fire YN-560 IV?)
- Yongnuo YN-E3-RX (a receiver-only trigger for the Canon RT system)
Most of the answers on the internet seem to be outdated (before these two flashes were released) or don't address this particular setup.
I've also read that a flash cannot be a slave and master at the same time.
What is currently relevant for me:
- to be able to fire and control Canon 430EX III-RT power
- to be able to fire and control Yongnuo YN-560 IV power
What is currently irrelevant for me:
- E-TTL support
- HSS support
- 2nd curtain
- remote shutter
What is currently undesired for me:
- optical triggering
- having a flash unit mounted on hot shoe
The setup I found which is the closest to desired is:
- RF-603 mounted with 430EX III-RT
- YN560-TX mounted on camera's hot shoe to trigger RF-603 and both YN-560 IV
But it does not allow me to control Canon 430EX III-RT power.
