The Manfrotto 300N allows accurate panoramic shots to be created. A variable number of click-stop positions can be set to precisely match the lens in use. The camera can be mounted directly, or via a plate adaptor or head (3/8" screw). A secondary locking screw prevents accidental movement when using heavy equipment, and the click-stop selector screw is attached by a cable to prevent loss. Base connection is 3/8".
