Profoto B2 250 Air TTL to-go kit

The Profoto B2 250 Air TTL Location Kit is a lighter, more portable counterpart to the B1.  The B2 consists of a battery pack and a head.  A handy carrying bag gives you the option to put the battery pack on your shoulder or hip, while the head is small and light enough to be mounted onto a monopod or a bracket on the camera, allowing the photographer to stay moving.  Alternatively, both the pack and head can be put on a stand and the B2 can be wirelessly controlled from the camera.  This makes the B2 the world's first off-camera flash that can be used both on and off-camera. 

The B2 is a lighter, more portable counterpart to the B1. The B2 head is small and light enough to be put on a bracket on your camera. Do either that or put it on a monopod or stand. The choice is yours. Both solutions have their advantages but are equally convenient. The B2 offers full TTL operation with both Canon and Nikon cameras. Canon shooters attach the Air Remote TTL-C to their camera’s hot shoe, Nikon shooters the Air Remote TTL-N. Then point and shoot, and the B2 will automatically adjust its light output to provide you with the perfect exposure. It is as easy as it sounds. The B2 is designed to help you to add a little or a lot of extra light wherever it is needed. The entire B2 kit fits in a bag no larger than your average shoulder bag. Where and how you shoot is all up to you.

At full power, the B2 will recharge in 1.35 seconds. At lower power settings, it will produce up to 20 flashes per second, eliminating the risk of missing that perfect shot waiting for the flash. Also note that the B2 has High-Speed Sync (HSS) functionality, giving you full control of the available light. The built-in reflector creates a wide and even light spread that is beautiful on its own. But that is only the start. In total, more than 150 tools are available to choose from. With the B2, light shaping is easy and limitless.
