High ratio zoom lens housed in a compact construction and incorporating Sigma's original OS (Optical Stabilizer) function.
This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma's original OS (Optical Stabilizer) function. This system offers the use of shutter speeds approximately 4 stops slower. This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8. It is the ideal lens for several type of photography such as landscape, snap shots and close-up photography. SLD(Special Low Dispersion)glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus.

Large aperture standard zoom lens provides superior performance both for Digital SLR Cameras and 35mm Film SLR Cameras.

To achieve an F2.8 aperture at all focal lengths, it employs three aspherical Lens to provide optimum aberration compensation. Two Special Low Dispersion (SLD) glass elements are provided for color aberration compensation, to assure high image quality.


Optimized for digital SLR cameras
It incorporates "Super Multi Layer Coating" to reduce the influence of harmful light caused by reflections from the digital image sensor.
Excellent correction of aberrations
Two SLD elements, one Glass Mold Aspherical plus two Hybrid Aspherical lenses provide excellent correction of various aberrations and a high level of optical performance.
Minimum focusing distance of 40cm (15.7 inches)
The lens has a minimum focusing distance of 40cm (15.7 inches) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.8.
DF (Dual Focus) System
This lens incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during autofocusing, and yet provides a large focus ring for easy manual focusing.
Petal Type Hood
Since the front of the lens does not rotate, a Petal-type hood and circular polarizing filters can be easily used.

Telephoto zoom lenses with tele-macro function, optimized for digital cameras
The high performance telephoto zoom lens is ideal for digital SLR cameras. This lens has two SLD glass elements in the front lens group and one in the rear lens group It is able to shoot with maximum magnification 1:2 at the focal length of 300 mm. It’s the ideal lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range
OPTIONAL ACCESSORIES:
SIGMA DG UV 58mm
SIGMA DG WIDE CIRCULAR PL 58mm
LENS HOOD LH635-01 (supplied)

Super wide-angle zoom lens designed exclusively for digital SLR cameras.

This ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8 degrees (when Sigma mount is used) and it is exclusive to digital SLR cameras. SLD glass elements effectively compensate color aberration. Aspherical lenses provide maximum correction for distortion and various aberrations; high image quality is displayed throughout the entire zoom range. The HSM equipped models makes fast AF speeds and quiet shooting a reality, and it is also capable of full-time manual focus. It has a minimum focusing distance of 24cm (9.4”) at all focal lengths. It is also equipped with an integral Petal-type hood to block out extraneous light.

Sigma's 17-70mm DC macro lens is an ideal large-aperture standard zoom lens for Nikon digital SLR cameras with APS-C size image sensors, making it suitable for a wide variety of subjects. The lens offers a minimum focusing distance of 7.9 inches throughout the entire zoom range, along with a maximum magnification of 1:2.3 for close-up macro photography. The new lens design and multilayer lens coating, meanwhile, reduce flare and ghosting--a common problem with many digital cameras. Add in a Special Low Dispersion (SLD) glass element and two aspherical lens elements and you have a lens that can correct all types of aberrations while producing a high level of optical performance at every interval.

The lens also offers a large aperture of F2.8 at the 17mm wide-angle setting, yet is notably compact, with an overall length of 3.2 inches and a diameter of 3.1 inches. Plus, it performs superbly even in relatively low-light conditions, such as indoors or at dusk. Users will also appreciate the inner focusing system, which provides a fast autofocus speed while preventing the front of the lens from rotating, making it particularly suitable for use with circular polarizing filters and petal-shaped lens hoods. Also equipped with a zoom lock switch that eliminates "zoom creep" during transport, the lens weighs 16 ounces and carries a one-year warranty.

Large aperture zoom lens designed specially for use with digital SLR cameras with a minimum focusing distance of 20cm (7.9").
This lens is specially designed to suit the characteristics of digital SLR cameras and provides a high level of optical performance. It has a large aperture of F2.8 throughout the entire zoom range, offers superior peripheral brightness as well as a compact and lightweight construction. A maximum magnification of 1:3, making it ideal for close-up photography.

Distinguishing characteristics

This is a large aperture prime lens with a standard focal length of 50mm, ideal for digital cameras. This lens is perfectly suited for a wide range of subjects enabling outstanding, sharply defined images against a nicely blurred background. The fast, F1.4 aperture makes this lens desirable for use with Digital SLR cameras. This lens effectively becomes an 80mm medium telephoto lens on digital cameras with APS-C size image sensors. The optimum optical design and molded glass aspherical lens elements provide excellent correction for all types of aberrations. This lens has superior peripheral brightness and provides sharp, high contrast images even at the maximum aperture. Superior optical performance is also ensured throughout the focusing range. The super multi-layer lens coating reduces flare and ghosting. This lens has a minimum focusing distance of 45cm (17.7”) and has maximum magnification of 1:7.4. It creates a very attractive blur, even when a small aperture is used.
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override.
