The other type of fisheye lens available is the diagonal variety which squeezes a 180° angle of view into a standard rectangular format. This new 10mm F2.8 EX DC Fisheye HSM from Sigma is just such a lens. That said, it captures a true 180° vista only when mounted in front of a Nikon DX sensor - users of Canon and Sigma DSLRs make do with 167° and 154° respectively. A built-in lens hood and HSM focusing are here and the lens will focus down to 1.8cm (0.7 in) from the front surface of the lens giving a reproduction ratio of 1:3.3.

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 cameras
  • 13.5cm 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.
