The Kirk FB-10 Double Arm Macro Bracket is designed for use with lenses that feature a rotating tripod collar. It requires the use of a Kirk Arca-type Lens Plate attached to the tripod collar, and connects to the bracket-mounting slot found on these plates.
The FB-10 features 2-way joints, with long flash arms that can be tilted downwards, which keep the flashes suspended above the end of the lens. This design makes the FB-10 ideal for macro and close-up photography. It also offers provision for the flashes to travel along the flash arms, and for them to be rotated according to the shooting angle.
Optionally, you can get the FB-10A adapter, which allows you to use the bracket even with lenses that do not feature a tripod collar.
