0.33x Super Fisheye Adapter for Sony Alpha a7S II (Fits Lenses with 62mm+ Filter Threads)

This 0.33x super fisheye adapter produces an extreme fisheye look with strong barrel distortion while avoiding vignetting. The optic amplifies perceived depth—pulling nearby subjects forward and making distant elements fall back toward the horizon. It is made for the Sony Alpha a7S II and mounts to lenses that have filter threads of 62mm and above. The design incorporates advanced high-index and low-dispersion optical glass, updated barrel materials, multi-layer anti-reflection coatings, and precision computer-aided-design / computer-aided-manufacturing to greatly reduce lens flare and ghosting caused by internal reflections. BAB (Internal Black Almite Barrel) features a black matte satin finish to cut stray reflections, and BRG (Black Rimmed Glass) helps prevent light bouncing off the glass edge.
