The Wimberley flash bracket system is beautifully engineered and highly modular; fitting together securely and providing you with an enormously versatile way of attaching flashes and accessories to your camera. Don't compromise: Build and modify your flash bracket system with pieces which precisely conform to your desired specification. The flash is connected via Arca-style QR clamps and all fitting knobs are captured, to prevent accidental loss. Module 8 allows the attachment of a F-1 telephoto bracket or several F-2 macro brackets to the camera body. There is also a small slider which lets you move the flash forward or backwards by small increments in order to precisely modify your macro lighting.
