Overview

For photographers already working within the Broncolor ecosystem, the RFS 2.1 Transmitter is the piece that makes a studio or location setup genuinely fluid. Instead of walking back to adjust a pack between setups, you stay behind the camera — dialing down a stop on your key, nudging the rim light, reading the scene as it lives and breathes rather than stopping to service your equipment. That kind of uninterrupted connection to the work shows in the pictures: better timing, more natural subject interaction, fewer missed moments while you cross the room.

The transmitter mounts cleanly to your camera's hot shoe and communicates over 2.4 GHz with 40 channel options — a practical necessity in multi-photographer environments. The build feels solid without being heavy, and the interface is straightforward enough to operate by feel once you're familiar with it. The 200-meter outdoor range is the standout specification for location shooters working with wide separation between camera and light — a real asset for commercial and fashion work where the lighting is pushed far into the frame. The 2-year warranty rounds out the package as a professional-grade accessory made for daily use.

Pros & Cons

👍 Pros

  • Precise 1/10-stop power control from camera position keeps your shooting rhythm unbroken during fast editorial or portrait sessions.
  • 40-channel selection makes it genuinely viable in multi-photographer environments without fighting for signal.
  • 200-meter outdoor range opens up location work — backlighting subjects at real distance with full power control.
  • Eliminates sync cables entirely, cleaning up your set and removing a common failure point during run-and-gun location shoots.
  • Two-year warranty backs the investment for working professionals.

👎 Cons

  • Only compatible within the Broncolor RFS 2 ecosystem — if you shoot mixed brands, this transmitter won't fire non-Broncolor units.
  • No TTL support — exposure is manual only, which requires more deliberate setup time compared to TTL-capable triggers.
  • Indoor range of 50 meters is adequate but not exceptional; some competing systems reach farther in signal-dense environments.
  • Premium pricing reflects the Broncolor ecosystem — a significant cost for a trigger if you're not already invested in the system.

Frequently Asked Questions

The RFS 2.1 works with Broncolor's Siros, Move, and Scoro systems that support RFS 2 protocol. Confirm your specific head or pack supports RFS 2 before purchasing — older Broncolor gear may require a different receiver.
You get full remote power control — both full-stop and 1/10-stop increments — directly from the transmitter on your camera. That means you can dial in exposure from across the studio without walking back to the pack.
With 40 selectable channels, you have plenty of room to avoid interference from other photographers or event AV systems. In dense RF environments like conference centers, switching channels is fast and the connection re-establishes quickly.
The spec lists 164'/50m indoors, which in practice covers most studio and event spaces comfortably. Large warehouse studios or venues with thick concrete walls may see that number shrink — test your environment before relying on it at distance.
The RFS 2.1 is a transmitter that mounts to your camera hot shoe. Broncolor heads with built-in RFS 2 receivers don't need a separate receiver unit, but if your older unit requires one, that's a separate accessory purchase.
