ProFoto B2 250Ws Off-Camera Flash Head

The ProFoto B2 Off-Camera Flash (OCF)  head is part of the OCF system. The B2 is conveniently compatible with other members of the OCF family like the B1 OCF. 

This OCF from Profoto is lightweight and small enough to fit into your hand, which is one of the reasons why it is so convenient to attach (with a bracket) on your camera, monopod or stand when shooting on-location.

On or Off-Camera Flash

The B2 head is small and light enough to be put on a bracket on your camera as well as a monopod or stand.

Full TTL

The B2 offers full TTL operation with both Canon and Nikon cameras via the optional Air Remote TTL-C or TTL-N transceivers. Just point and shoot - the B2 will automatically adjust its light output to provide you with the right exposure.


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.


At full power, the B2 head with its separately purchased power pack recharges in 1.35 seconds. At lower power settings, it will produce up to 20 flashes per second, catching even the most fleeting gestures.

Light Shaping

The built-in reflector renders a wide, even light spread that can be modified with any of the more than 150 optional light-shaping tools available.
