Sigma MACRO 105mm F2.8 EX DG OS HSM
Sigma takes its exceptional 105mm macro lens to the next level with the addition of optical stabilization
TORONTO, ON., July 25, 2011 – Gentec International is pleased to announce the new Sigma MACRO 105mm F2.8 EX DG OS HSM lens, a large aperture, medium telephoto lens offering advanced performance and featuring Sigma’s proprietary optical stabilizer (OS) system for handheld close-up photography. The new OS system adds greater versatility to this classic lens, which is ideally suited to portraiture and copy work, as well as extreme close-ups.
Focusing down to 1:1 magnification ratio at its closest working distance of 31.2 centimetres, this compact lens produces sharp, life size images of tiny subjects and details that often go unseen. 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, which 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.
The Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocus, as well as allowing full-time manual focus capability. A rounded nine-blade diaphragm creates an attractive blur to the out-of-focus areas of the image.
Included with the lens is a lens hood, plus a lens hood adaptor for use with APS-C sensor cameras where the effective focal length becomes about 150mm with most cameras. The suggested retail price of the Sigma MACRO 105mm F2.8 EX DG OS HSM lens is $1,199.99. The lens will be available for Canon in August, followed in September for Nikon and Sigma, and in November for Sony.
