Three Sigma lenses

Posted on

Three Sigma lenses are hitting retail shortly: 12-24 mm f/4.5-5.6 II DG HSM, APO 120-300 mm f/2.8 EX DG OS HSM and APO Macro 150 mm f/2.8 EX DG OS HSM.

Sigma 12-24 mm

The 12-24 mm lens, an extreme wide-angle lens, is optimized for use with DSLRs, and is an updated version of Sigma’s original 12-24 mm lens.

The new lens incorporates one Special Low Dispersion (SLD) glass element and four FLD glass elements, which have the performance equal to fluorite glass, to compensate for colour aberration and provide excellent image quality throughout the entire zoom range; Sigma’s Super Multi-Layer Coating reduces flare and ghosting. In addition, three glass-mold elements and one hybrid aspherical lens offer advanced performance in a compact and lightweight construction.

Sigma says the lens has superior peripheral brightness and provides sharp, high-contrast images, even at maximum apertures. Incorporation of a Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocus while allowing full-time manual focus override. The minimum focusing distance is 28 cm (11 inches) throughout the entire zoom range, and a maximum magnification ratio of 1:6.4. This lens also features Sigma’s weatherproof design for use in harsh conditions.

The suggested retail price of the Sigma 12-24 mm f/4.5-5.6 II DG HSM is $1,099.99. The Canon, Nikon, and Sigma versions will be available in May; the Sony version will be available in June, followed by Pentax later in the year.

Sigma 120-300 mm

The Sigma APO 120-300 mm f/2.8 EX DG OS HSM is a pro lens featuring Sigma’s proprietary Optical Stabilizer (OS) system. To meet pro needs, this lens features a weatherproof design. One Special Low Dispersion (SLD) and two FLD glass elements, which have the performance equal to fluorite glass, are used for maximum correction of chromatic aberrations, while Sigma’s Super Multi-Layer Coating reduces flare and ghosting. An inner focusing and inner zooming system ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare to produce ultra-high resolution images, comparable to a fixed focal length lens.

The OS system allows the use of shutter speeds up to four stops slower than would otherwise be possible, enabling handheld telephoto photography. Incorporation of a Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocus, while allowing full-time manual focus override. The rounded nine-blade diaphragm creates an attractive blur to the out of focus areas of the image.

The suggested retail price of the Sigma APO 120-300 mm f/2.8 EX DG OS HSM is $3,199.99. Versions for Canon, Nikon, and Sigma will be available in March.

Sigma APO Macro 150 mm

The Sigma APO Macro 150 mm f/2.8 EX DG OS HSM incorporates Sigma’s proprietary Optical Stabilizer (OS) system, enabling handheld, close-up photography.

The design of this high-performance lens includes a floating focusing system that moves two different lens groups in the optical path to different positions, compensating for astigmatic aberration and spherical aberration; the system also provides extremely high optical performance from infinity to 1:1 macro.

Three Special Low Dispersion (SLD) glass elements ensure excellent correction of all types of aberrations, while Sigma’s Super Multi-Layer Coating reduces flare and ghosting. The new lens also offers superior peripheral brightness and provides sharp, high-contrast images, even at the maximum apertures. The Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocus, as well as full-time manual focus capability. The rounded nine-blade diaphragm creates an attractive blur to the out of focus areas of the image. This lens also features Sigma’s weatherproof design.

The suggested retail price of the Sigma APO Macro 150 mm f/2.8 EX DG OS HSM is $1,399.99. Versions for Canon, Nikon, and Sigma will be available in April.
