Wireless Flash Trigger Yongnuo RF-603II C3 by Yongnuo — 2x Trigger Set for Canon Cameras

The Yongnuo RF-603II C3 wireless flash trigger set includes two transceivers designed for wireless flash and remote shutter control with compatible Canon cameras. Each unit can operate as either transmitter or receiver, allowing photographers to trigger off-camera flashes, release the shutter remotely, and build multi-light setups without relying on camera TTL. The compact units mount on standard hot shoes and communicate on a radio frequency to provide consistent triggering across short to medium distances, making them suitable for event, portrait and studio applications.

Advantages

The RF-603II C3 offers interchangeable transmitter/receiver operation in a two-piece kit, simplifying setup for off-camera lighting and remote shooting. Radio-based communication reduces line-of-sight limitations compared with optical systems, improving reliability in varied shooting environments. The design is compact and mounts directly on camera and flash hot shoes, providing straightforward integration with existing gear and quick deployment for on-location or studio work.

Suitable for

• Off-camera flash photography
• Portrait and studio lighting setups
• Event and wedding photography where remote triggering is required
• Creative multi-flash arrangements and light shaping
• Remote shutter release for long exposures and group shots

How to use

Attach one RF-603II C3 unit to the camera hot shoe and mount the second unit on the flash or place it on a stand using the tripod socket. Turn on both units and set them to the same channel so they can communicate. Use the camera to trigger the shutter; the transceiver on the flash will fire in sync with the camera. Switch either unit to transmitter or receiver as needed for different configurations, such as multiple flashes or remote shutter release. Consult the included user guide for channel selection and battery installation details.

For stable results, test trigger operation and sync timing before critical shoots, verify battery charge in both units, and secure flashes on stands or use safety clips to prevent accidental falls. When using multiple flashes, group them and confirm consistent channel settings to avoid misfiring.
