Wireless Trigger Controller Yongnuo YN622C-TX for Canon — TTL/Manual Control for YN622C Transceivers

The Yongnuo YN622C-TX wireless trigger controller for Canon is a handheld flash controller designed to work with YN622C transceivers. It supports through-camera TTL pass-through, manual power adjustments and high-speed sync functionality, allowing photographers to control off-camera flash groups and channels directly from the camera position. The unit streamlines flash configuration for both studio and location shoots and provides instant access to exposure-related settings without removing the camera from the hotshoe.

Advantages

The controller offers TTL compatibility for automated flash exposures as well as full manual power control for precise light shaping. Group and channel selection is available for multi-flash setups, and the device supports high-speed sync for shutter speeds beyond the camera’s standard flash sync limit. Its user interface places controls and settings within easy reach, reducing the need to handle individual transceivers on each flash. The YN622C-TX is compact and mounts on the camera hotshoe for immediate integration into existing Canon setups using YN622C transceivers.

Suitable for

• Event and wedding photography requiring quick on-camera flash adjustments
• Studio shoots with multiple off-camera flashes and group control
