This lightweight lens is easy to carry and use in a wide variety of photographic scenes. At the same time, as may be expected of a member of our high-performance Contemporary line, this lens features all the core functionality you need for your photography, including dust and splash resistant structure, a zoom lock switch that can be set for any focal length, a water- and oil-repellent lens coating, an easily accessible AF/MO/MF switch, and a newly designed tripod socket. This lens is also compatible with SIGMA’s newly developed teleconverters (sold separately), with which it offers AF up to F8.
