Profoto OCF Softbox 1x3' is part of the Off Camera Flash accessory system intended for the B2 and B1 OCF flash heads. Light weight and speed are evident throughout its construction. The fixed front diffuser saves on setup time, as do the color-coded support rods that mount quickly to the separately-purchased, patent-pending speedring. This 1x3' strip softbox is ideal for use as a hairlight or rimlight on a stand or overhead on a boom. It also produces a long elegant highlight in reflective objects in product or tabletop work. An optional fabric grid is available to narrow the softbox's beam and add directional control.
