Sigma 8mm f/3.5 EX DG Circular Fisheye Lens Overview
Presenting an impressively unique 180° angle of view, the t Sigma 8mm f/3.5 EX DG Circular Fisheye is a creative tool for producing dramatically distorted, circular imagery. Benefiting 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.
Circular fisheye lens is designed for full-frame cameras, however can also be used with APS-C models where it provides a 12.8mm equivalent focal length.
Expansive 180° angle of view pairs with the fisheye design to render circular imagery within a black frame. This design also renders scenes with exaggerated distortion and curved lines for a creative, distinct aesthetic.
