Product description from Sigma
At launch 2007 Sigma wrote this regarding Sigma EX 4,5mm f/2,8 DC HSM Fisheye:
"Sigma’s 4.5mm F2.8 EX DC Circular Fisheye HSM creates an image that is a circular, curved, distorted view of reality when used on a digital SLR camera. One of the most unusual lenses a photographer can use as it produces a circular image within a black surrounding frame. It is ideal for landscapes and panoramic photography. Because of its equisolid angle projection system, the lens can be used for scientific applications. The minimum focusing distance of 5.3 inches allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. SLD (Special Low Dispersion) glass employed for effective compensation of color aberration, Super Multi-Layer lens coating reduces flare and ghosting and assures high image quality throughout the entire zoom range. In the hands of a photographer looking for creative expression and the opportunity to explore and create, this is the ultimate creative tool. The results are captivating
For use with smaller chip APS-c cameras only
The circular field of view produces striking images with exaggerated perspective of near subject & extreme barrel distortion of the surrounding areas
HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus
The minimum focusing distance of 5.3 inches & a magnification ratio of 1 to 6 allows subjects to be as close as ¾ of an inch from the lenses’ front element.
A front cap adapter, front/rear lens cap and carrying case are included with the lens."
