SIGMA 17-70mm F2.8-4 DC OS Macro C Nikon F-Mount

The SIGMA 17-70mm F2.8-4 DC OS Macro C is a versatile standard zoom lens designed for APS-C format DSLR cameras. With a focal length range equivalent to 25.5-105mm on 35mm cameras, this lens combines a fast f/2.8 maximum aperture at the wide end with Optical Stabilisation for steady handheld shooting. The Contemporary series lens features 17 optical elements in 13 groups, including FLD and SLD low-dispersion glass alongside aspherical elements to minimise chromatic aberration and distortion. Built from Sigma's Thermally Stable Composite materials, it is approximately 30% smaller and lighter than conventional designs without compromising build quality or optical performance.
