B1X Location Kit 500 AirTTL US The best-selling battery-powered TTL flash

Product number: 901027-US

The Profoto B1X off-camera flash is the successor of the award winning Profoto B1. The B1X is no stay-at-home flash; it’s for the adventurous photographer who likes to get out there on location in the real world. The portable B1X offers cordless, battery-powered freedom and flexibility. After all, there aren’t many wall sockets in the middle of a desert or half way up a mountain. B1X provides you with easy light-shaping wherever and whatever your location might be thanks to its dedicated system of lightweight OCF Light Shaping Tools that are designed for maximum mobility and ease of use.

It offers automatic TTL shooting that shines brightest in challenging lighting conditions. It offers HSS that enables you to control and shape light even in broad daylight. And it’s fast to set up so you’re free to explore and create stunning images. Let your imagination set the limits, not the length of your cables. The B1X gives you the power you need in all the right places.
