Dovetail Adapter for legacy lens plates
The FB-A adapts older lens plates to accept our current design of flash brackets which require a mounting plate that features a double-dovetail design. The FB-A is compatible with all Really Right Stuff and Kirk lens plates that do not already feature a double dovetail design.
The FB-A raises the clamping surface for the flash bracket by 2/10ths of an inch. There must be, at a minimum, 5/8-inch of clearance from the surface of the plate to the barrel of the lens.
