The greatest advantage of this lens is that one can capture 1:1 magnification (life-size) images from a further away, thanks to its 180mm focal length. The lens has an internal floating focusing mechanism. It also has USM (Ultra-sonic Motor) for silent and fast auto-focusing.
Another telephoto macro lens with a maximum magnification of 1x. Life-size close-ups can be taken from a farther distance without disturbing the subject (insects, etc.). The internal floating system minimizes fluctuations in aberrations caused by changes in the focusing distance. Optical performance is outstanding from 1x to infinity.
