I am a bit confused by your statement Haydon, have you purchased a YongNue transmitter or a Canon ST-E3-RT which is Canons transmitter designed for the Speedlite 600EX RT.
As Wall-E suggested, if you have a wireless or radio transmitter you do not need a cable connected to your flash. However having a cable release connected to your camera (not to your flash) to fire the shutter does has benefits and is a good idea to purchase the relevant one for your camera. Cheers
I purchased the YongNue transmitter which has just been released. Normally I'd buy the Canon but at half the price plus an IR beam this is the way I chose. I hope it won't be disappointing.
