The CF16 Fresnel is a compact motorized Aputure Mount fresnel with a 16-inch diameter lens and a spot-flood range of 18 Degree - 50 Degree . It is designed for use with the Storm XT52. The CF16 Fresnel efficiently intensifies the native light output of the Storm XT52 by up to 7x. It provides a smooth falloff from center to edge, all with a compact and lightweight form factor achieved by a dual-expanding focusing system.This unique system allows the CF16 to increase the distance between its rear and front elements by extending both ends of its barrel, not just the front like traditional fresnel accessories. With a motorized focusing system, the CF16 can be precisely controlled at the fixture's lamp head or remotely via Sidus Link, Sidus Link Pro, or a lighting control console via Dmx. The CF16 Fresnel can be paired with the included CF16 Barn Doors to give users more shaping control over the output of their Storm XT52.
