Litepanels Deluxe Ball Head Shoe Mount

The ball joint gives free aim in every axis and locks with one knob, which is what you want on top of a camera when the light has to be angled off-axis to kill a reflection.

Litepanels lists it as fitting all of its on-camera fixtures, so it works across the small panel range rather than being tied to one model. Fits All Litepanels on-camera fixtures. Order as Litepanels part number 900-0007.
