Profoto continues to affirm their commitment to full-featured flash systems with onboard TTL capability with the introduction of the impressive, battery-powered B10 OCF Flash Head. Part of the OCF family which began with the reduced-size B2 power pack, continued with the full-sized B1X monolight, and most recently the A1 shoe-mount Studio Light, the B10 combines the best characteristics of the monolight with those of auto-exposure, on-camera flashes. In a move that's consistent with their ongoing "techno-logic" Profoto packs all the features of the previous OCF lights into the 7" B10.
