0.4x Super Fisheye Adapter — Cinema-Quality for Panasonic HC-X1

The 0.4X Super Fisheye Adapter delivers an extreme fisheye look with pronounced barrel distortion while maintaining full-frame coverage without vignetting. It intensifies perceived depth by bringing foreground subjects visually closer and pushing background elements toward the horizon. Optical performance benefits from advances in high-index / low-dispersion optical glasses, updated barrel materials and modern anti-reflection coatings, plus the latest computer-aided-design / computer-aided-manufacturing techniques. A Crystal optics AR coating minimizes light loss and flare to less than 1% per surface. Construction details include BAB (Internal Black Almite Barrel) — a black matte satin finish that cuts internal reflections — and BRG (Black Rimmed Glass), which helps prevent light from reflecting off the lens edge.
