0.33x Super Fisheye Adapter for Sony Alpha a99 II (Fits 62, 72 or 77mm Filter Threads)

This 0.33x Super Fisheye Adapter produces an extreme fisheye look with a strong barrel distortion while avoiding vignetting. It accentuates perspective — bringing close subjects forward and pushing distant elements toward the horizon — for dramatic wide-angle images on the Sony Alpha a99 II when mounted on lenses with 62, 72, or 77mm filter threads. Optical and mechanical design improvements use high-index / low-dispersion optical glass, updated barrel materials, and anti-reflection coatings, all developed with modern computer-aided-design / computer-aided-manufacturing techniques to significantly reduce lens flare and ghosting from internal reflections. Key construction features: - BAB (Internal Black Almite Barrel): internal black matte satin finish that minimizes internal reflections - BRG (Black Rimmed Glass): black rim around the glass element to lessen the chance of light reflecting off the edge Together these elements deliver the pronounced fisheye effect and controlled image quality this adapter is designed for, without introducing unwanted vignetting or excessive flare.
