Dedicated to the Aputure Spotlight Mount system, this 19° Lens allows you to produce a controlled 19° beam of light with clean edges and faithful color rendering. The lens's design helps to limit chromatic aberrations around the edge of the illumination circle, and keeps fringing levels at 1mm from a distance of 1.6'. When used with a Light Storm LC 120d II, light output up to 10x brighter is possible, and the lens housing design permits quick installation and removal from the Spotlight Mount.
