Profoto B1 500 AirTTL

The B1 500 Air TTL is a 500W battery powered flash with built in Air (radio receiver) capable of TTL metering and High Speed Sync when used with the compatible Profoto Air Remote for Canon, Nikon, Sony and Olympus.

It is notably powerful for its compact size. Packed with 500Ws of light, it is about ten times as powerful as the average speedlight. This is enough to overpower the sun on a sunny day, or to light up larger sets or groups of people. 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.
