Sigma 8mm F/3.5 EX DG Circular Fish Eye Lens -Canon

 Presenting an impressively unique 180° angle of view, the Sigma 8mm f/3.5 EX DG Circular Fisheye Lens is a creative tool for producing dramatically distorted, circular imagery. Designed for full-frame-format Canon EF DSLRs, this lens intentionally does not cover the full image frame and rather produces a fully circular image in the center of a black frame. One Special Low Dispersion (SLD) glass element is incorporated in the lens design and helps to reduce some chromatic aberration and color fringing for increased clarity. The lens also features a close minimum focusing distance of 5.3", along with a 1:4.6 maximum magnification ratio, to enable creative close-up shooting from unique perspectives. An internal focusing design maintains the overall length of the lens during use, and a selector switch allows you to quickly change between autofocus and manual focus settings.
