Available in stock Add to Basket


The Profoto B1 500 Air TTL is a powerful, cordless, easy to use and versatile off-camera flash for studio and on location shoots. Powered by an exchangeable battery and wirelessly synced and controlled with the Air system, it allows the photographer to bring the B1 anywhere and place it without regard to cable length. The battery will provide up to 220 full-power flashes, while the Air system has an operating range up to 1,000ft.


The most notable feature of Profoto’s ground breaking invention is the TTL function that integrates flash and camera which automatically adjusts its output to provide you with a perfect exposure. Photographers who prefer adjusting the light themselves can switch to manual control by a simple button-press.

The Canon Air Remote TTL-C (rented separately) is a small, hot shoe-mounted device that acts like a wireless link between camera and flash, supporting manual and TTL control of B1 lights in up to 3 individual groups. The Air Remote TTL-N for Nikon cameras with i-TTL support will be available in 2014.
The light output can be controlled in 1/10 f-stop steps over the entire 9 f-stop power range. The B1 is also equipped with a high-efficient LED modeling light, powerful enough to be used as a portable video light.
