0.4x Cinema-Grade Fisheye Adapter for JVC GY-HM600

The 0.4X Super Fisheye Adapter creates an extreme fisheye appearance with strong barrel distortion while avoiding vignetting. It enhances perceived depth by pulling close subjects forward and making distant elements recede toward the horizon. Optical design incorporates advanced high-index / low-dispersion glass, updated barrel materials and anti-reflection coatings, all produced using the latest computer-aided-design / computer-aided-manufacturing methods. A Crystal optics AR coating limits light loss and flare to less than 1% per surface. The BAB (Internal Black Almite Barrel) uses a black matte satin finish to cut reflections, and BRG (Black Rimmed Glass) helps prevent light from reflecting off the lens edge.
