The Wimberley M1 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. Module 1 is a quick release arm and the clamp's screw is captive so that it cannot come off from being unscrewed too far.
