The Optical Quality Appears to be Virtually Identical to Nikon's

Sigma 10mm f2.8 EX DC Fisheye HSM Lens The HSM provides autofocus performance as fast as the Nikon (at least on my Nikon D300 DSLR), while being eerily quiet. As for the optical quality, it appears to be virtually identical to Nikon's, which is to say excellent. Both lenses are slightly soft wide-open (i.e. at f/2.8), but sharpen considerably when close down one f-stop. Indeed, both lenses are almost as sharp at f/4 as they are at f/5.6. Besides the built-in autofocus motor, another difference between Nikon and Sigma's fisheye lenses is the field-of-view (FOV). Sigma's lens is 0.5mm wider, and provides a small -- but definitely noticeable -- increase in the angle of view.

Fisheye lens with close up ability designed exclusively for use with APS-C size digital SLR cameras, 10mm F2.8 EX DC Fisheye HSM

This autofocus fisheye lens is designed for use with digital SLR cameras equipped with APS-C size image sensors. The Nikon version produces a diagonal angle of view of 180, 154 for Sigma, 167 for Canon.

The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion. The minimum focusing distance of 13.5cm / 5.3inch, and maximum magnification 1:3.3 allows subjects to be as close as 1.8cm/0.7inch from the lens front element.

This close focusing capability allows close-up photography and also it is possible to make use of large depth of field that covers wide range of subjects. The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality.

The HSM "Hyper Sonic Motor" ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring. This lens is supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters.

HSM means this lens will autofocus on Nikon D40/D40x, Nikon D60, Nikon D3000, Nikon D3100 and the Nikon D5000

A fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image. Originally developed for use in meteorology to study cloud formation and called "whole-sky lenses", fisheye lenses quickly became popular in general photography for their unique, distorted appearance. They are often used by photographers shooting broad landscapes to suggest the curve of the Earth. Hemispherical photography is used for various scientific purposes to study plant canopy geometry and to calculate near-ground solar radiation.

The first types of fisheye lenses to be developed were "circular fisheyes" lenses which take in a 180 hemisphere and project this as a circle within the film frame. Some circular fisheyes are available in orthographic projection models for scientific applications. These have a 180 vertical angle of view, and the horizontal and diagonal angle of view are also 180. Most circular fisheye lenses cover a smaller image circle than rectilinear lenses, so the corners of the frame will be completely dark.
