Profoto B1 500 AirTTL MonoKit x2 Batteries Rental
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.
Busy photographers can literally set up their lights, slip the optional Air Remote TTL-C or TTL-N transmitter onto their camera's hot shoe and point-and-shoot without taking a reading and testing. Traditionally point-and-shoot would be a suspect term for a pro, but not if you're shooting back to back jobs on an impossible schedule with what you thought was an undoable deadline. Composition, posing etc, is of course up to the photographer, but time after time the B1 will give you a first shot exposure that's a keeper.
