The compact & ergonomic Manfrotto 055 Mag Ball Head Q6 is a professional ball head built for the Manfrotto 055 carbon fibre tripods & enables extra-smooth & precise movements. The 055 features a portrait angle selector of 90-105-degrees & is designed to give better, easier camera control & framing accuracy. The 055 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. 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.
