A lens which joins Canon's existing 28-105 f/3.5-4.5 USM in the line-up. It's the smallest and lightest zoom in the 28-105 class, and its optical system includes an Aspherical element. Most noteworthy is its Micro USM -- half the size of previous Micro USMs, and its use of internal focusing (no front element rotation during focusing).
