Yongnuo RF-603 2.4GHz Wireless Remote Flash Trigger Transceiver

for Canon (with C3 cable)


Like RF-602, the new RF-603 supports all Canon DSLR Camera and support Flash Speedlite with " Sleep mode" function:

  • Nikon
  • Canon
  • Olympus
  • Pentax
  • Samsung
  • and other flashgun which has " Wake up " function


The RF603 has been improved in several functions:

  • Transceiver-based system: units automatically detect when to switch to either transmitter or receiver mode.
  • Hotshoe pass-through, allowing on-camera flash and radio triggering to be used simultaneously.
  • Improved shutter sync speed up to 1/320s
  • Use AAA batteries
  • Improved on/off switch
  • Prontor/Compur (PC) port for off-hotshoe synchronisation
  • Non-proprietary 2.5mm (sub-miniphone) port for shutter release cables
  • Shutter release cable included (C1 cable in this packing)

Since it is now a tranceiver system you can now use it more flexible. With e.g. 4 RF-603 you can trigger 3 flashes (1 trigger, 3 receivers) as well as trigger the camera itself and then trigger 1 flash. One more good thing is that the only powersource you now need is 2 AAA batteries/accus. There is no need for CR3 batteries anymore and you can use your standard charger.

The power switch has been improved an now should prevent from accedently firing in the camera bag which could consume a lot of the battery power.
