Producing a truly distinct image quality, the 6.5mm f/2 Circular Fisheye Lens from Opteka is a Fujifilm X-mount lens providing a 9.75mm equivalent focal length. Its fisheye design realizes an impressive 190° angle of view along with a unique circular image shape and strong distortion for a surreal quality. One super-low dispersion element is featured in the optical design, and helps to minimize color fringing and chromatic aberrations in order to realize high clarity and color accuracy. An HD anti-reflection coating has also been applied to suppress flare and ghosting for greater contrast in bright lighting.
