VST’s unique optical design allows there to be some space between the lens and the object permitting the placement of lighting devices. With standard fisheye lenses or lenses that have a short focal length, the WD is also short and which doesn’t leave any room for lighting. It also has a manual Iris/Focus, which is critical for maximizing its DOF.
