Product description from Sigma

At launch 2007 Sigma wrote this regarding Sigma EX 10mm f/2,8 DC HSM Fisheye:

"Sigma’s 10mm F2.8 EX DC Fisheye HSM lens is a diagonal fisheye which means the distorted scene is shown full frame within the camera’s field of view. The diagonal field of view produces striking images with exaggerated perspective of near subject & extreme barrel distortion of the surrounding areas. It allows photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. The diagonal fisheye is the most popular kind of fisheye and are often used by wedding photographers who want to give an “artistic” looks to images, by underwater photographers who want to take in the maximum field of view possible and by scenic photographers. The minimum focusing distance of 5.3 inches and magnification ratio of 1 to 3.3 allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. In the hands of an artist this lens can produce memorable, eye-catching images.

For use with smaller chip APS-c cameras only

HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus

Super Multi-Layer lens coating reduces flare & ghosting & assures high image quality throughout the entire zoom range

The minimum focusing distance of 5.3 inches & a magnification ratio of 1 to 3.3 allows subjects to be as close as ¾ of an inch from the lenses’ front element

Supplied with a gelatin filter holder at the rear for easy addition of color correction filters

A front cap adapter, front/rear lens cap and carrying case are included with the lens."
