0.33x Super Fisheye Adapter for Nikon D810 (Fits Lenses with 62mm+ Filter Threads)

Transform a compatible lens on your Nikon D810 into an extreme fisheye with this 0.33x adapter. It produces pronounced barrel distortion and a dramatic fisheye perspective while avoiding vignetting — nearby subjects appear pushed forward and distant elements drop back toward the horizon for exaggerated depth. Optical construction uses high-index, low-dispersion glass along with updated barrel materials and advanced anti-reflection coatings. Combined with modern computer-aided design and computer-aided manufacturing (CAD/CAM), these refinements significantly reduce flare and ghosting from internal reflections. Design details include BAB (Internal Black Almite Barrel) — a black matte satin finish to minimize stray reflections — and BRG (Black Rimmed Glass) to lessen light bounce at the glass edge.
