PROFOTO 901168 B10 PLUS OCF FLASH DUO KIT

Profoto knows when it's got a good thing but rather than rest on its laurels and enjoy the ride, they continue to tweak and enhance the product as they have done previously with the B1/B1X and the D1/D2. Such is the case with the augmented B10 Plus OCF Flash Head, which at 500Ws offers double the power of its predecessor.

Like the B10, the B10 Plus is part of the OCF (Off Camera Flash) family and in a move that's consistent with their ongoing "techno-logic", Profoto packs all the features of its forerunner (and then some) into the B10 Plus.

The 500Ws light has a 10-stop variable power range and swift recycle times of 0.05 to 2.5 seconds. Freeze Mode, which prioritizes flash duration yields a very short 1/50,000 second at minimum power. The B10 Plus is powered by a lithium-ion battery that gives you 200 full-power flashes on a 90-minute charge, while 60 minutes will top up the battery to 80% if you're short on time. Of course, the B10 Plus retains TTL technology that takes advantage of your DSLR's flash auto-exposure system and significantly shortens the time between inspiration and execution and capture. The path to this great feature is purchase of an optional wireless radio Air Remote TTL controller, which is currently made for Nikon, Canon, Fujifilm, Olympus, and Sony cameras.
