The FB-9 flash bracket is designed for lenses that have a rotating tripod collar, utilizing a single flash unit. These brackets attach directly to any of our Kirk Arca-style lens plates (check the lens plate section for the correct plate that fits your lens). This flash bracket has a deluxe 2-way joint to allow positioning of your flash in any direction, making it truly a macro bracket. The FB-9 is sold with a KC1FP quick release plate.
