The M-9 Module is a combination vertical upright and Arca-Swiss style quick-release attachment that is useful for several flash applications.
It is part of the Wimberley Modular Flash Bracket System.
The M-9 Module is most commonly used in conjunction with the M-3 Tilt Arm to form the F-9 Wimberley Head Version II Flash Bracket.
The F-9 Flash Bracket attaches directly to the Swing Arm of the Wimberley Head Version II.
Since it attaches to the Head instead of the lens, it stays on the Head when you switch lenses, which can be extremely helpful in the field.
On the Sidemount Wimberley, the F-9 attaches to the lens plate.
