Sigma 17-70mm f/2.8-4.5 DC Macro HSM

Description

The lens is ideally suited for a wide variety of subjects and is designed specifically for digital SLR cameras featuring APS-C size image sensors. The Nikon fit version also includes an HSM auto focus motor.

A lens specially designed to suit the characteristics of digital cameras

This revolutionary lens has a minimum focusing distance of 20cm (7.9”) throughout the entire zoom range. A maximum magnification of 1:2.3 enables extreme close-up photography. An impressive achievement for a standard zoom lens.

Multi Layer Lens Coating

The new lens design and multi-layer lens coating reduce flare and ghosting, a common problem with digital cameras.

SLD Glass Elements

A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.

Fast F2.8 Aperture

This lens offers a large F2.8 aperture at 17mm wide angle and yet it is compact, with an overall length of just 82.5mm (3.2”) and diameter of 79mm (3.1”). Performance is superb, even in relatively low light conditions indoors or at dusk.

Inner Focus System

The lens is equipped with an inner focusing system, which prevents the front element from rotating making it particularly suitable for petal shaped hoods and circular polarizing filters.

Zoom Lock

The lens is also equipped with a zoom lock that eliminates ‘zoom creep’ during transit.
