Manufacturer description

An ultra wide angle lens covering an angle view of 100 deg. It is the lens to take photographs of big contructions or to use when taking pictures close to the subject. It has an extreme depth of field and strong perspective. The distortion aberration, which is always a problem with the super wide angle lenses, has been nearly corrected. The picture is quite clear even at the minimum focusing distance of 25cm thanks to Sigma's Floating Focus System. In addition, F2.8 is the biggest aperture ratio in its class. The "Perfect Hood", to prevent ghosts or flares, is of a design which does not interfere with your filter work.
