Manfrotto MH055M0-Q6 tripod head

055 magnesium ball head, w/ Q6 Top Lock quick release A professional ball head built for compatibility with 055 carbon fiber tripods, the 055 is extremely precise, providing extra-smooth movements. Compact, ergonomic, powerful, durable and made of lightweight magnesium, the 055 also has uniquely innovative features like the exclusive 90°-105° portrait angle selector, designed to give better, easier camera control and framing accuracy.
The 055 is complemented by the new Q6 Top Lock quick release system, developed to offer photographers a fast, easy to use and very secure camera quick release mechanism suitable for heavy pro equipment. The camera plate clicks into the clamp from above, and as soon as it engages, it triggers a safety pin that stops the plate and camera from sliding out accidentally. Even before the clamp is locked, the camera is securely supported. The clamp has 3 bubble spirit levels (one for each axis of rotation) to facilitate precise framing and help produce straight images in-camera, ensuring the camera's full frame is usable and reducing post-production time. The Q6 system is also compatible with Arca-style quick release plates and heads from other manufacturers.
