Hey Guys!
I like to have an off-camera flash set up to create some rim lights while I use my main on-camera flash as main light source. But sometimes I'm moving all around and bouncing the flash off the walls and light does not hit the off-camera flash therefore it does not trigger.
I've seen canon speedlite transmitters to trigger them via radio frequency, but the transmitter would not allow me to have an on-camera flash at the same time.
How could I achieve to have an on-camera flash (Canon 580 EXII) and trigger an additional flash via radio frequency?
I can't recall if I've ever done it, or if it would work, but how about putting a RF transmitter/transceiver on your hot shoe in between the camera and the on-camera flash? Maybe it could be used to trigger the flash it's connected to, as well as transmit to your other receivers. Maybe it'd need a PC sync (or whatever applicable wired connector between the transmitter and flash).
yes this or plug a transmitter into the PC sync jack on your camera (if it has one)
The only way to use on-camera flash with an off-camera slave flash without using cables is by adding a flash on top of your transmitter.
The built-in flash is a no-go once a transmitter is installed.
Cheapest way is:
2* Yongnuo transm/receiver kit or 2 transceivers ( a transceiver is a device that can be used both as a transmitter and a receiver ), cheapest ones are RF-603C if I recall the model number correctly ( about $20-25 the kit off ebay ) and the "premium" version YN-622C ( about $70 for a dual kit [ two transceivers ] ).
1* Yongnuo ( my recommendation for OEM flash, small difference between their top speedlights and the top speedlights from Canon/Nikon ) flash ( either the YN-568EXII or the 560, the 568EXII is E-TTL & HSS capable ) [ about $120 ]
Don't the Canon 600ex's have the ability to control other 600ex's via rf when used as on camera flash so you dont need the ste3rt?
