A professional ball head built for compatibility with 057 carbon fibre tripods, the 057 is extremely precise, providing extra-smooth movements. Compact, ergonomic, powerful, durable & made from lightweight magnesium, the 057 also has uniquely innovative features like the exclusive 90°-105° portrait angle selector, designed to give better, easier camera control & framing accuracy. The 057 is complemented by the new Q6 Top Lock quick release system, developed to offer photographers a fast, easy to use & very secure camera quick release mechanism suitable for heavy pro equipment. The camera plate clicks into the clamp from above, & as soon as it engages, it triggers a safety pin that stops the plate & 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 & help produce straight images in-camera, ensuring the camera's full frame is usable & reducing post-production time. The Q6 system is also compatible with Arca-style quick release plates & heads from other manufacturers.
