This standard-wide lens is good for everyday, general photography, has a fast F1.8 maximum aperture, which is ideal for lowlight shooting, and features a macro function with a ration of 1:2.9.
Its Super Multi Coating reduces flare and ghosting, and incorporates a Dual-Focus mechanism and two aspherical lens elements to minimize distortion, chromatic aberration and astigmatism.

This large aperture 30mm F1.4 EX DC HSM lens is designed for APS-C size image sensors of digital SLR cameras and features two SLD glass elements to reduce chromatic aberration as well as glass mould aspherical lens for high-quality images.

Its 30mm focal length makes it a standard wide to normal view to cover your basic photography needs, like snapshots and small group shots.
The HSM (hyper Sonic Motor) provides quiet high-speed auto-focus shooting, as well as full-time manual focus and its large maximum aperture of F1.4 can perform in lowlight conditions.

This large-aperture wide-angle lens is equipped macro focusing capability with a maximum magnification of 1:2.7 and a fast F1.8 maximum aperture for shooting in lowlight conditions. The use of aspherical lenses offers for superior peripheral brightness and compensation of aberrations and astigmatism. This is an ideal DG lens for Digital SLR cameras.

This is a large aperture prime lens with a standard focal length of 50mm, ideal for all digital SLR cameras and is suitable for a wide range of subjects. The fast, F1.4 aperture makes this lens great for shooting at fast shutter speeds or in lowlight conditions. This lens effectively becomes an 80mm medium telephoto lens on digital cameras with APS-C size image sensors and its optical design and molded glass aspherical lens elements provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting and incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override

This wide-angle lens is ideal for scenic shots, landscapes and large-group photos, and is supplemented with a large aperture for lowlight. Its 94.5° angle of view allows close up photography surrounding the photographic subject, and the lens incorporates technologies such as The Dual-Focus (DF) mechanism and aspherical lens elements, which compensates for distortion, spherical aberration and astigmatism.

This Fisheye lens is powered by a Hyper Sonic Motor (HSM) for fast and silent focusing and is designed exclusively for use with APS-C size digital SLR cameras

The Sigma Corporation is pleased to announce the launch of the new 10mm F2.8 EX DC FISHEYE HSM lens.
Offering a diagonal angle of view of 180°, this fisheye lens produces striking images with exaggerated perspective and distortion and features close focusing capability for close-up photography as well as 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.

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, thanks to the quantifiable angle/area relationship it produces.
