This incredible lens is the smallest and lightest in its class. Its totally new optically, with an Aspherical element to keep the quality up and the size down.

Even more noteworthy is an entirely new Micro USM, that's about half the length of previous designs--with the same focusing power and performance.

Features like circular diaphragm blades (for natural backgrounds) and internal focusing (the front element never rotates) round out this great new lens.
