Canon EF 180mm f3.5L Macro USM AutoFocus Telephoto Lens for Canon SLR Cameras International Version

Bring small things into full-sized view with the Canon EF 180mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The 180mm lens offers such features as three UD glass elements and an internal floating system, which combine to minimize aberrations caused by changes in the focusing distance; an advanced ultra-sonic monitor (USM) for high-speed, quiet autofocusing; full-time mechanical manual focusing; and a focusing distance range of 1.57 feet to infinity.

Compatible with the EF Extender 1.4 x and 2x, the lens carries a one-year warranty.
