Manfrotto Q6 Top Lock Quick-Release 054 Magnesium Ball Head is a dynamic, lightweight mechanism that is compatibly constructed for 190 carbon fiber tripods. This Tripod Accessory from Manfrotto includes features such as a distinctive 90 degree-105 degree portrait angle selector that provides accurate framing and simpler camera control. Manfrotto Q6 Ball Head 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. Manfrotto Q6 054 Ball Head has a camera plate that 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. Manfrotto Q6 Tripod Ball Head System is also compatible with Arca-style quick release plates and heads from other manufacturers. For skilled photographers, Manfrotto Bogen Tripod Accessories provide the durability and first-rate features necessary to capture that outstanding snapshot.
