Sigma Press Release
105mm f/2.8 EX DG OS HSM
Medium telephoto macro lens incorporating Sigma’s Optical Stabiliser
The Sigma Corporation is pleased to announce that the Sigma MACRO 105mm F2.8 EX DG OS HSM is now available in Sony AF fit.
The successor to the Sigma MACRO 105mm F2.8 EX DG, introduced to market in June 2004, this large aperture medium telephoto macro lens incorporates the latest optical design technology, offering advanced performance for 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 optional APO Tele Converters. Sigma’s own proprietary OS (Optical Stabiliser) function helps with handheld close-up photography and the HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability.
This lens features a splash resistant design for use in harsh conditions and a rounded 9 blade diaphragm creating a smooth blur to the out of focus areas of the image.
