Autofocus lens for macro photography up to life-size (1x) magnification. Inner focusing affords a long working distance of 5.9in. (149mm) at 1x. A 3-group floating system results in excellent delineation at all focusing distances. Ring USM for silent and high-speed AF, and full-time manual focusing also provided.

Features

	Entirely new optically, with a three-group floating system for exceptional close-up performance.
	The first lens in its class to feature innner focusing. The lens length never changes, even at life size!
	A secondary diaphragm blocks stray light at f/2.8, increasing contrast when shooting wide-open.
	Ultrasonic Motor provides outstanding AF speed at all focusing distances.
	Wide manual focusing ring with smooth action, and full-time manual focus even in AF mode.
