 The 0.3X Super Fisheye Adapter provides an extreme fisheye effect and a high degree of barrel distortion without vignetting

It exaggerates depth by pulling nearby objects closer and causing distant objects to recede into the horizon. Advances in high-index / low-dispersion optical glasses, new barrel materials, and anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing

Greatly reduces the appearance of lens flare and ghosting caused by reflections

BAB (Internal Black Almite Barrel) Black matte satin finish which reduces reflections. BRG (Black Rimmed Glass) Reduces the chance of light reflecting off the edge.
