Overview

The Profoto Air Remote TTL-C (model 901039) is a hot-shoe-mounted wireless transmitter and controller purpose-built for Canon cameras. It brings full E-TTL automatic exposure control to Profoto B1 and B2 flash heads, allowing the camera's metering system to set flash power wirelessly — no test shots or manual chimping required. For all other Profoto Air-compatible strobes, it provides remote manual triggering and power adjustment, making it a central control point for mixed Profoto setups.

Operating on a 2.4 GHz frequency band, the remote offers 8 selectable channels with 3 groups per channel, giving photographers the flexibility to run up to 24 independently addressable zones in a shared environment. TTL triggering reaches up to 330 feet, while manual triggering extends to an impressive 1,000 feet — more than enough for large event spaces, outdoor editorial work, or stadium-scale productions. First and rear curtain sync options add creative control over motion rendering. The compact body sits cleanly on the camera's hot shoe and adds negligible weight, keeping the shooting experience agile even during long handheld sessions.
