0.4x Super Fisheye Cinema Adapter for JVC GY-HM200 — Extreme Barrel Distortion, No Vignetting

Transform your JVC GY-HM200 with a 0.4x Super Fisheye Adapter that delivers an extreme fisheye look and pronounced barrel distortion while maintaining full-frame illumination with no vignetting. Close subjects are pulled forward for exaggerated depth, and distant elements compress toward the horizon for dramatic perspective. Optical and manufacturing enhancements include high-index / low-dispersion optical glasses, updated barrel materials, and advanced anti-reflection treatments. These improvements are produced using modern computer-aided-design / computer-aided-manufacturing processes to ensure precision and consistency. Crystal optics AR coating reduces light loss and flare to less than 1% per surface, preserving contrast and color fidelity. Additional flare- and reflection-control features: BAB (Internal Black Almite Barrel) — a black matte satin finish that minimizes internal reflections; and BRG (Black Rimmed Glass) — which lowers the chance of light reflecting off the lens edge.
