The invention discloses a single-lens reflex camera tripod with a transversely-moving function. The single-lens reflex camera tripod comprises a tripod head; the bottom of the tripod head is fixedly connected with a transversely-moving device; the two sides of the transversely-moving device are rotationally connected with transversely-moving plates through movable pieces; the bottom of the transversely-moving device is fixedly connected with a support table; the bottom of the support table is rotationally connected with a foot stool through a movable piece; the bottom of the transversely-moving device is fixedly connected with a middle rod; the bottom end of the middle rod penetrates through the support table, and extends to the bottom of the support table; and the two sides of the bottom end of the middle rod are rotationally connected with support cylinders through movable pieces. The single-lens reflex camera tripod relates to the technical field of digital camera accessories. The single-lens reflex camera tripod with the transversely-moving function enables the tripod head to be capable of driving a single-lens reflex camera to stably and horizontally move thereon; and when a lens needs to move in panorama shot and the like, manual holding of the camera to move is not needed, so that the stability of the single-lens reflex camera is maintained, and the effects of transverse moving and incapability of shaking the lens are achieved.
