    Overview

    The Canon EF 70-300mm f/4-5.6L IS USM is a compact, well-built telephoto zoom with excellent optics and fast autofocus. It offers sharp images, though it is a variable-aperture lens (f/4-5.6). Build quality is outstanding, with full weather sealing and fluorine coatings that resist moisture and dust. The lens is relatively light for an L-series, making it ideal for travel. It suits photographers who need a durable, portable telephoto with good reach, but its f/4-5.6 aperture may limit low-light performance.
