Compact, uncluttered and relatively lightweight for a head of its quality, the Arca Swiss P0 dispenses with the usual locking knobs in favour of a locking collar which runs all the way around the base of the head, so that you can lock and unlock the head from any angle of operation. It s an easy and intuitive way of adjusting the tilt, even when wearing gloves or in difficult lighting conditions. The head s asymmetrical ball is a classic Arca Swiss design feature, which increases resistance as the head is moved away from the vertical axis. This helps in handling the camera and prevents the camera from flopping over loosely during positioning and potentially causing damage (to equipment and fingers!). Up to 90° of tilt may be achieved and the panning action (positioned near the base of the head) allows the head to be rotated through a full 360°. This variant is supplied without a quick release mounting and is topped with a flat, ¼ inch threaded platform. 3/8 inch adapter screws are included.
