Overview

The Godox CT-16 Flash Trigger Kit is a wireless radio triggering system designed for photographers who need reliable off-camera flash synchronization without the complexity or cost of TTL-enabled systems. Operating on a 433MHz frequency, the kit consists of a CT-16 transmitter that mounts to your camera's hot shoe and a CTR-16 receiver that connects to your studio flash via the included sync cable and convert adapter. The radio signal does not require line-of-sight, allowing you to position lights behind diffusers, around corners, or in other locations where infrared triggers would fail.

Setup is intentionally simple: match the channel on the transmitter and receiver, and the system is ready to fire. The transmitter ships with a 23A 12V battery rated for over ten thousand actuations, while the receiver runs on two AAA batteries (not included). Maximum sync speed reaches up to 1/250 second, though this varies by camera model. The kit is compatible with Canon, Nikon, Sony, and other standard hot shoe cameras, and each receiver drives one studio flash — additional receivers can be added for multi-light configurations. For photographers who control flash power manually and want a straightforward, affordable wireless trigger, the CT-16 covers the fundamentals reliably.

Key Features

Compatibility Note: Ensure transmitter and receiver are set to the same channel for synchronization. Remove the transparent film on the transmitter before use. Contact us for any inquiries.

Pros & Cons

👍 Pros

  • 433MHz radio frequency provides reliable, stable transmission that does not require line-of-sight like optical triggers.
  • Universal hot shoe mount and included sync cable ensure broad compatibility across Canon, Nikon, Sony, and other camera systems.
  • Transmitter battery is included and rated for over ten thousand firings, keeping long-term operating costs low.
  • Simple channel-based pairing makes setup quick with no complex menu systems or firmware to configure.

👎 Cons

  • Does not support TTL auto-exposure or high-speed sync, limiting it to manual flash power control only.
  • Kit includes only one receiver, so multi-light setups require purchasing additional CTR-16 receivers separately.
  • Maximum sync speed of 1/250s varies by camera body and may be lower on some models.
  • Build quality is lightweight plastic, which is functional but may not withstand heavy daily professional abuse.
