Manfrotto 056 lens mount_LTM 4-lens 3D camera originally designedThe Manfrotto 056 is a simple three way tripod head for still cameras. Three low profile knobs, thumbscrew (with standard 1 4" thread) for camera mounting. With the exception of the knobs, it's all metal. Cosmetic condition is good, but this head appears to have paint and finish imperfections from the factory. Why? Not sure. Works well, though.
