(for Wimberley Head Version II)
This bracket consists of modules M3 & M9. It attaches directly to the Arca-Swiss style dovetail on the swinging arm of the Wimberley Head Version II. Since it is attached to the head and not your lens, it remains in place when you switch lenses. The bracket folds flat for easy storage.
The F-9 bracket has been designed to clamp to both the swing arm of the V-2 Wimberley and to the plates so it can be used when working on the ground or from the car, but I still prefer the F-1 to the F-9 in these situations as it gives you more flexibility.
