A rapid-orientation head for optical and photographic apparatus in general includes a ball joint having a first attachment on one side, for attachment to a support, and having a handle on the other side, a second attachment on the handle for restraining the optical apparatus thereon, and a reversible lock for the ball joint which is mounted on the handle in order to permit the relative orientation between the first and second attachments. The handle extends transversely with respect to the direction joining the first and second attachment means.
