Sigma 17-70mm f/2.8-4 DC OS HSM for Nikon
The Sigma 17-70mm f / 2.8-4 DC Macro OSM HSM for Nikon is a standard zoom lens specially designed for DSLR with APS-C sized image sensors. This lens has a 35mm equivalent focal length range of 25.5-105 mm, which provides wide-angle to vertical viewing angles for use in daily shooting situations.
This lens has a maximum aperture of f / 2.8-4 fast to help control your focus plane better and to help in low light shots. A built-in optical stabilizer also helps in low light situations by providing a four-stop reduction in the appearance of camera shake, which is also ideal for macro and telephoto shooting. The Hyper Sonic AF Motor offers fast, smooth and silent autofocus that greatly benefits video applications. The integration of two FLD lenses, one SLD and three aspherical lenses in the construction helps to reduce the effects of chromatic and chromatic axial aberrations, and the elements coated with multiple superlayers help to increase the contrast to obtain clear and clear images.
This lens has a maximum magnification of 1: 2.8 and a minimum focusing distance of 8.7 "/ 22 cm, which provides a working distance of only 2.2" / 5.5 cm when shooting at a focal length of 70 mm.
The OS (Optical Stabilizer) system is built into the lens to provide a reduction equivalent to four stops in the appearance of camera shake. This allows greater possibilities of hand shooting when working in low light situations, at longer focal lengths, and when working with macro subjects.
