Great light made easy with the Profoto B1
The B1 off-camera flash is not a stay-at-home flash. Its TTL function shines the brightest in challenging lighting conditions. Its cordless operation unleashes your creativity and makes it want to run free in the wild.
5 reasons to choose the Profoto B1
The unique AirTTL feature provides perfect exposure without manual metering, making it quick and easy to catch not only the moment, but also light it in a creative way. Please note that an AirTTL Remote optional transmitter needs to be attached to your camera in order to use this feature.
Without cables or cords
The B1 is powered by an exchangeable, high-capacity battery that is integrated with the flash. Combine that with any of the wireless transmitter options offered within the Profoto Air System and experience the freedom that comes with working without cables and cords.
The B1 is packed with 500Ws of light, enough to shape and control the light even in difficult sunny conditions. The output range is 9 f-stop controlled in 1/10 f-stop increments, providing optimal control and flexibility.
At full power, the B1 will recharge in less than 2 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 B1 has High-Speed Sync (HSS) functionality, giving you full control of the available light.
With light shaping
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 B1, light shaping is easy and limitless.
