8mm f/3.5 EX DG Circular Fisheye Lens for Canon EF
Product Description
Presenting an impressively unique 180° angle of view, the Canon EF-mount Sigma 8mm f/3.5 EX DG Circular Fisheye is a creative tool for producing dramatically distorted, circular imagery. Benefitting the unique look of the lens is an advanced optical design that utilizes one SLD glass element to reduce color fringing and chromatic aberrations for improved clarity. A Super Multi Coating has also been applied to suppress lens flare and ghosting for greater contrast and color accuracy. Additionally, the lens also features a close 5.3" minimum focusing distance of 5.3", along with a 1:4.6 maximum magnification ratio, to suit working with close-up subjects.
