Sigma 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.

Sigma 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM

• The first 180 degree circular fisheye lens designed specifically for APS-C size digital SLR cameras
• Fast F2.8 maximum aperture making it ideal for low light photography
• Minimum focusing distance of 13.5cm and a maximum magnification of 1:6
• SLD glass minimizes color aberration
• Equipped with HSM with full-time manual focus override
• Equisolid angle projection method is possible for art and scientific use

The Sigma Corporation is pleased to announce the launch of the new 4.5mm F2.8 EX DC CIRCULAR
FISHEYE HSM lens.

This autofocus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively
designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital
SLRs with APS-C size image sensors, it produces circular image within the frame.

The F2.8 large aperture value produces a bright image in the viewfinder and allows photographers to take pictures in low light conditions, making it an ideal lens for Astrophotography and Aurora photography. Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific and arts applications such as solid angle measurements of cloud distribution over the sky or vegetation distribution of the forest.

The minimum focusing distance of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly
useful for close-up photography. SLD (Special Low Dispersion) glass provides effective compensation of
chromatic aberration. Sigma’s Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with
an inner focusing system that creates high definition and good image quality over the whole frame. The HSM ?Hyper Sonic Motor? ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.

Hopefully both of these will make there way onto Canon’s APS-C sized DSLRs like the EOS 40D, 30D, 20D, 400D (Digital Rebel XTi ), 350D (Digital Rebel XT), 300D (Digital Rebel). These would be a great addition to the lens selection for these bodies, and usually at a price break over a Canon alternative. What remains to be seen is the quality, so we’ll watch for those reviews to come shortly after release.
