This lens, the new product line C - Contemporary, mainly used for everyday photo situations, offers a focal length range equivalent to 25.5-105mm for a 35mm camera. The most important features of a standard zoom lens for digital SLR cameras are: to guarantee high image quality, to meet the requirements of a wide variety of occasions and to be handy and compact. The Sigma 17-70mm F2.8-4 DC Macro OS HSM removes the usual limitations of a standard zoom and offers a short focusing distance, sufficient telephoto focal length and a comfortable light intensity. The lens, equipped with an initial speed of F2.8, is surprisingly compact. It is suitable not only for popular travel or family snapshots, but also for somewhat more creative photos. This lightweight lens, which you can carry with you at all times, is easy to use and its ease of use will satisfy even the most demanding users.
