 Sigma 105mm F2.8 EX DG OS HSM Macro lens : Sigma is pleased to announce that its newly upgraded Sigma 105mm F2.8 EX DG OS HSM macro lens is now available for a retail price of $1.400 USD. The updated Sigma 105mm macro lens features Sigma’s own proprietary Optical Stabilizer technology, which allows for high-performance close-up photography. The telephoto reach makes it a perfect macro lens for capturing images of insects and small creatures. Additionally, the wide maximum aperture combined with a short telephoto focal length make it very favourable for facial portraiture at lower magnification. A special low dispersion lens and one high refractive index lens provide excellent corrections for all types of aberration and distortion.

Sigma 105mm macro lens
The Sigma 105mm F2.8 EX DG OS HSM macro lens features a floating focusing system that 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 Sigma 105mm macro lens with Sigma’s APO teleconverters. Sigma’s Hyper Sonic Motor feature ensures quiet and high-speed autofocus as well as full-time manual focus capability. The Sigma 105mm macro lens also has a rounded nine-blade diaphragm that creates an attractive blur to the out-of-focus areas of the image.
