Wimberley 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 Perpendicular Plate gives you a dovetail plate that is perpendicular to the original direction of your camera body plate.
Since the dovetail on most camera body plates is oriented perpendicular to the axis of the lens, adding the perpendicular plate gives you a dovetail plate that is parallel to the axis of the lens. This is useful for attaching telephoto and macro brackets to your camera body. The Perpendicular Plate can also be used to make small forward and backward adjustments for macro photography.
