Whenever Profoto introduces a product, anyone in the photo world sits up and takes notice since at the very least, it's going to be impressive. The introduction of the B1 500 AirTTL is truly ground-breaking or to be more accurate, game-changing.
Based on the popular D1 Air series of monolights, all of the familiar professional and convenience features we've come to expect from Profoto are onboard. The B1 has the same dense, durable polymer housing, integrated 77-degree reflector, built-in receiver compatible with Air transmitters and intuitive highly visible controls and display as the D1 but with two striking differences - battery power and TTL camera/flash integration.
