The second new fisheye lens from Sigma is the 10mm F2.8 EX DC Fisheye HSM designed for APS-C sized sensors. This lens provides a 180° angle of view only when used with a Nikon DX sensor( Canon(1.6x): 167°, Sigma: 154° ). But unlike the 4.5mm fisheye, 10mm squeezes the frame into a standart rectangular format. Sigma 10mm offers a fast maximum aperture of f/2.8 and HSM focusing, and a minimum focus distance of 1.8cm giving a magnification ratio of 1:3.3.

Press Release:
Fisheye lens with close up ability designed exclusively for use with APS-C size digital SLR cameras 10mm F2.8 EX DC FISHEYE HSM
Fisheye lens designed specifically for APS-C digital SLR cameras13.5cm minimum focusing distance and 1:3.3 maximum magnification allows close up photography Equipped with HSM allowing full-time manual focus override
Equisolid angle projection system is possible for art and scientific use. The Sigma Corporation is pleased to announce the launch of the new 10mm F2.8 EX DC FISHEYE HSM lens. 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.
