The EF 70-300mm f/4-5.6L IS USM is a high quality telephoto zoom lens for Canon EOS Cameras. This is not a typical run of the mill 70-300mm f/4-5.6 lens. It's an L-Series lens. Canon reserves this designation for their very best stuff; only the leading lenses that are on a level above their contemporaries get to wear the red L, the red ring, and sometimes that instantly recognizable white paint.
While 70-300mm f/4-5.6 lenses have been popular, practical, portable options for years Canon has significantly enhanced that potential by finally making one that is professional. With-in the boundaries of this well known focal length and aperture formulation, Canon has reworked the rest. The result of apparently sparing no expense and holding a design to their highest standards is a state of the art lens with top tier optical and mechanical construction.
19 elements in 14 groups include 2 UD (Ultralow Dispersion) elements and it's all put together quite properly. An internal focus design is paired with a fast USM (Ultra Sonic Motor) for super quick autofocus. The IS Image Stabilization reduces loss of sharpness due to camera shake and allows handheld use of shutter speeds up to 4 stops slower than would otherwise be possible.
The fit and finish are solid. The lens features weather and dust seals as well as flourine coating on the front for easier cleaning. Space is provided for an optional rotating tripod mount.
This sharp, stabilized, handy, fast focusing lens is fun to use and a great choice for any photographer who wants a dependable well built tool to help them take great pictures. It's a perfect versatile lens with lots of reach and many possible applications.
Recommended accessories include the ET-73B Lens Hood, LP-1424 Lens Case, and Tripod Mount C (W II).
Optimized to deliver ultra-high quality images and lightning fast operation, the new Canon EF 70-300 f/4-5.6L IS USM telephoto zoom lens brings a popular zoom range to the commemorate Canon L-series of lenses.
