0.4x Cinema-Grade Fisheye Adapter (49mm) for Sony NEX-VG900

This 0.4X Super Fisheye Adapter produces an extreme fisheye appearance with a strong barrel distortion while avoiding vignetting. The effect intensifies depth perception—pulling close objects forward and making distant subjects recede toward the horizon. Optical construction benefits from high-index, low-dispersion glass, upgraded barrel materials and anti-reflection coatings, all developed using modern computer-aided-design / computer-aided-manufacturing techniques. A Crystal optics AR coating limits light loss and flare to less than 1% per surface. Mechanical and finish details include BAB (Internal Black Almite Barrel) — a black matte satin finish that reduces reflections — and BRG (Black Rimmed Glass) to minimize the likelihood of light reflecting off the lens edge.
