Sigma 8mm F/3.5 EX DG Fisheye SA Mount Lens {Rear Gel} Description

Details

Sigma’s 8mm F3.5 EX DG Circular Fisheye lens is an unique approach to artistic photography. Fisheye lens creates curved distorted view of reality. It allows photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. This Sigma fisheye produces a circular image with a 180º angle of view within a black surrounding frame. A minimum focusing distance of 5.3 inches and a magnification ratio of 1to 4.6 allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. 

This circular fisheye lens produces circular images with an angle of view of 180°and also incorporates an auto focus system to achieve accurate focusing that might be difficult through the camera's viewfinder due to the extremely large depth of field. This lens is perfectly suited for low light conditions indoors or at dusk. Special Low Dispersion (SLD) glass offer effective compensation of color aberration. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific applications such as solid angle measurements of cloud distribution over the sky, or vegetation distribution of the rain forest canopy.
