Canon Lens EF180MM 1:3.5 L MACRO USM Black

EF180MM 1:3.5 L MACRO USM - Lens This telephoto macro lens is capable of close-ups up to 1X without any adapter. It is ideal for photographing insects and small animals, where a long working distance is desirable, as minimum focusing distance is 0.48m. Three UD (Ultra-low Dispersion) glass lens elements (2nd, 4th and 11th) correct secondary spectrum and ensure sharp definition at all subject distance. By employing floating construction, lens extension is reduced and f value fluctuation is minimized. A ring USM (Ultrasonic Motor) provides silent AF and full-time manual focusing. As the lens length does not change during focusing, accessories such as Macro Ring Light at the front end of the lens, can be easily operated. Maximum magnification can be increased either 1.4X or 2X by using Extender EF1.4X or EF2X.
