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 Moto--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.
