One SLD and four FLD glass elements compensate for color aberration and provide high image quality.Three glass mold elements and one hybrid aspherical lens give advanced performance and compact and lightweight construction. The Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp and high contrast images even at the maximum apertures.

Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed auto focus, while allowing full-time manual focus override. This lens has a minimum focusing distance of 28cm (11.0") throughout the entire zoom range and a maximum magnification ratio of 1:6.4. In addition, this lens features splash proof design for use in harsh conditions.

SIGMA MACRO 105mm F2.8 EX DG OS HSM

This large aperture medium telephoto macro lens offers advanced performance of close-up photography. Sigma's own proprietary OS (Optical Stabilizer) system enables handheld close-up photography.A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion.A floating focusing system moves two different lens groups in the optical path to different positions.

This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.The Super Multi-Layer Coating reduces flare and ghosting, providing high contrast images. It is also possible to use this lens with Sigma's APO TELE CONVERTERS. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens features a splash proof design for use in harsh conditions and a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image.

Sigma's proprietary OS (Optical Stabilizer) system offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible, enabling hand held tele-photography. Six SLD glass elements compensate for chromatic aberrations and provide high image quality throughout the zoom range. The Super Multi-Layer Coating reduces flare and ghosting and ensures sharp and high contrast images even at the maximum apertures.

The lens design adopts an inner focusing and inner zooming system to provide convenient handling and the HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus while allowing full-time manual focus override. This lens has a minimum focusing distance of 80cm (31.5”) and a maximum magnification ratio of 1:6.3. The rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the image. The addition of Sigma's TELE CONVERTER 1.4x EX DG APO or 2x EX DG APO produces a 70-210 F4 AF telephoto zoom lens or 100-300 F5.6 AF telephoto zoom respectively.
