B2 Location Kit 250 AirTTL The portable TTL flash for photographers on the move
Product number: 901110-US
Pack light and give yourself maximum mobility on location with the versatile, battery-powered Profoto B2. The B2 is a powerful option, 5 times more powerful than an average on-camera flash. And it’s made for light shaping with a dedicated range of OCF Light Shaping Tools that are designed for maximum mobility and ease of use.
Its small, lightweight pack and head help you stay one step ahead of the action. They fit neatly into a handy carrying bag and provide you with a portable flash that weighs a shade over 2 kg (4.4 lbs).
The B2 is most definitely not a stay-at-home flash. It offers automatic TTL shooting that shines brightest in challenging lighting conditions, and HSS that enables you to control and shape light even in broad daylight. You can respond to any situation by using it either on or off camera. You’re free to work without restraint or limitation and move freely, so it’s ideal for busy events where you need maximum flexibility or when you don’t have assistants to help out.
