The Profoto B1 500 Air TTL Off-Camera Flash is a new kind of flash that will completely change the way you think about lighting. The B1 is TTl, so you get a perfect exposure in a flash. What's more, it's battery powered and cordless, meaning you can take it with you whenever, wherever. Combine this with the already outstanding power and light shaping possibilities that Profoto is known for, and you have an off-camera flash that will revolutionize the way you shoot. Off-Camera Flash with TTL Attach the Air Remote TTL to your camera's hot shoe to merge camera and flash into one. Then point and shoot, and the B1 will automatically adjust its light output to provide you with the perfect exposure. It is as easy as it sounds. Cordless The B1 is powered by an exchangeable, high-capacity battery that is integrated with the flash. Combine that with an Air Remote TTL and experience the freedom that comes with shooting without power cables or sync cords. Powerful and Speedy Ten times as powerful as the average speedlight, the B1 enables you to overpower the sun on a sunny day as well as light up larger backgrounds and areas. Having that much power also allows you to add Light Shaping Tools to create a beautiful, soft light even in bright conditions. At lower power settings the B1 will blast away up to twenty flashes per second. But speed also equals short flash duration. In other words, the B1 will provide a much shorter flash duration than a speedlight set to the same output. Patent pending AirTTL technology takes the concept of "point and shoot" to the next level. Exchangeable, integrated battery provides up to 220 full-power flashes per charge. Cordless design and wireless Air technology allows you to shoot without cords and restraints. Quick burst capability eliminates the risk of missing that perfect shot waiting for the flash. 500Ws adjustable in 1/10 f-stop increments over a 9 f-stop power range give you both power and precise control. Compatible with a wide range of Profoto Light Shaping Tools.
