The Profoto B1 is a 500Ws cordless off-camera flash, offering TTL metering with Canon and Nikon cameras, in connection with a hotshoe-mounted Air Remote TTL unit. The remote is sold separately, so that photographers may choose the right remote for their camera. The Air Remote TTL-C for Canon cameras with E-TTL II support is launched together with the B1. The Air Remote TTL-N for Nikon cameras with i-TTL support will be available in 2014. The 500Ws light output is enough to overpower the sun on a sunny day, or to light 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.
