The Wimberley F-6 has a system of flash bracket components that are modular, versatile and easily stowed in a small space when not in use. Known as the Shape-Shifter Modular Flash Bracket System, the components connect without tools. None of the combinations slip, twist or creep-even during intense action. They're integrated with the venerable Arca-Swiss type quick release system, now dominant as the industry standard for macro and telephoto shooting.The Combo 6 is all you need to use a flash directly over the lens center with the Wimberley Sidekick gimbal head adapter. As with all of the Shape Shifter components and unlike other manufacturer's products, parts are captive to prevent detachment from accidentally unscrewing them too far while in the field. Total weight of this combination is 0.39 lb.
