Delivering both circular and rectangular fisheye effects, the Nikon F-mount Meike MK-6-11mm f/3.5 Fisheye Lens is characterized by its notable distortion and rounded image quality along with an immense 180° angle of view. Covering a 9-16.5mm-equivalent range, the unique zoom design adds flexibility to this specialized ultra-wide lens. Its optical design features aspherical elements to improve sharpness by reducing spherical aberrations. Additionally, individual lens elements feature a multi-layer coating to control surface reflections, flare, and ghosting in order to realize a high degree of contrast and color accuracy, even when working in bright and backlit conditions.
