0.4x Super Fisheye Adapter — Cinema-Grade for Panasonic HC-X920

This 0.4X Super Fisheye Adapter delivers an extreme fisheye look with a pronounced barrel distortion while avoiding vignetting. It accentuates spatial depth by pulling foreground subjects forward and causing distant elements to fall back toward the horizon. Optical and mechanical improvements include high-index / low-dispersion glass elements, updated barrel materials, advanced anti-reflection coatings, and production using the latest computer-aided-design / computer-aided-manufacturing techniques. The Crystal optics AR coating limits light loss and flare to less than 1% per surface. Built-in flare and reflection control features: BAB (Internal Black Almite Barrel) with a black matte satin finish to reduce internal reflections, and BRG (Black Rimmed Glass) to minimize edge reflections.
