The 19 Degree Spotlight Lens is for the Aputure Spotlight Mount. The lenses for the Spotlight Mount were designed with professionals in mind. In addition to allowing the C300d II and 600d Pro to produce 10 times its original output, the high-resolution lenses produce an even beam of light, with minimal light falloff on the edges, while maintaining a shift in color temperature of less than 200 degrees Kelvin. The Spotlight Mount’s new lens technology minimizes chromatic aberrations around the edge of the illumination circle. Compared to similar ellipsoidal fixtures, the Spotlight Mount significantly decreases its edge color fringing to a mere 1mm at a distance of 5 meters. Like typical ellipsoidal lights, the Spotlight Mount also offers simple user-interchangeability between Aputure’s 19°, 26° and 36° lenses, whether you need a wider illumination circle or pinpoint accuracy. Combined with the internal shutters, filmmakers will be able to gain more control of the shape of their light.
