Sigma 8mm f3.5 EX DG Circular Fisheye Lens - Canon Fit

This 8mm f/3.5 Circular Fisheye lens for Canon cameras creates circular images with an angle of view of 180° when attached to a full-frame digital or 35mm film SLR camera. It has a fast maximum aperture of F3.5 and a minimum focusing distance of 13.5cm. Sigma’s super multi-layer coating and Special Low Dispersion (SLD) glass provide excellent image quality for digital and film SLR cameras. This fisheye lens integrates an auto focus system to perform accurate focusing that may be difficult through the camera's viewfinder because of the overly large depth of field. This lens is ideal for low light conditions, indoors or at dusk. This circular fisheye lens has a minimum focusing distance of 13.5cm and a maximum magnification of 1:4.6 making it particularly useful for close-up photography. Special Low Dispersion (SLD) glass gives effective compensation of colour distortion. Sigma’s super multi-layer lens coating diminishes flare and ghosting, a frequent problem with digital cameras and also creates an optimum colour balance. This lens is ideal for photographers using computer stitching software which requires circular fisheye images to be input. Also a holder at the rear of the lens accepts gelatin filters.
