Sigma 17-70mm F/2.8-4.5 DC Lens For Sony Alpha Mount {72} Description


The Sigma 17-70mm offers a relatively long zoom range 4x ratio coupled with an impressive large maximum aperture at 17mm and 7.87" minimum focus distance with 1:2.3 max magnification ratio. The 17-70mm DC is specifically designed for the reduced image circle of today's APS-C DSLRs where the field of view is equal to 26-150mm (full format). Optimized with tight controls, no wobbling and a mild Zen finish is great for everyday use.

It can be used with wide variety of subjects and it is an ideal large aperture standard zoom lens for digital SLR cameras featuring APS-C size image sensor. The new lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. 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.
