Add a professional ball joint head to your tripod or monopod using this Medium Ball Fixed Camera Head from Monoprice! This camera head is constructed of aviation grade anodized aluminum for superior strength and durability; as well as light weight. It features a quick release sliding plate with a patented safety locking system to ensure that your camera does not accidentally fall off the head; even when the QR lever is released. The sliding plate features a standard 1/4"x20 threaded screw mount and rubber pads to ensure a positive grip on your camera; while preventing any scratching caused by slack in the mount. It includes two levels; one horizontal and the other vertical; so that it can be adjusted for exact leveling whether it is used horizontally; or tilted 90 degrees to one side. A locking lever on the body locks the ball joint in place; while a corresponding locking knob locks the azimuth adjustment. The base features a mark every 5 degrees of panning; so you can accurately adjust for panoramic shots. The head mounts onto a standard 3/8"x16 threaded head mount screw. The head is 3.4" 86mm tall; weighs 11.3 oz. 320g ; and supports up to 33.1 lbs. 15kg of weight.
