It is a maximum aperture of F3.5, a minimum focus distance of 5.5 cm and a maximum magnification of 4.6x. Special fisheye design allows maximum creative expression. Sigma lens coating Super multi-layer reduces glare and ghosting, a common problem with digital cameras. The new lens power layout reduces color lenses. The excellent image quality for digital and film SLRs. These lenses can be used for scientific applications such as solid angle measurements of cloud distribution on the sky, the vegetation distribution in the canopy, etc., because the angular relationship / quantitative yield of the region. This lens holds a gelatin filter in the rear, allowing the use of gelatin filters [via]
