Overview: The Canon EF 16-35mm f/2.8L III USM lens is an
ultra-wide zoom lens for Canon EOS full-frame and
APS-C cameras. When
used on APS-C cameras, the focal length is equivalent to 26-56mm. The lens
is ideal for photographing landscapes, portraits, and close-ups. With a large f/2.8 aperture, you can
shoot at dusk or dawn, inclement weather, in dimly lit rooms, or other low-light
situations. The lens has a
standard Canon EF-mount, and comes with front and rear lens caps, a lens hood,
and soft storage case.
Lens Construction: The lens features a new optical design to
improve the sharpness in the outer edges and corners. With 16 elements in 11
groups, the EF 16-35mm f/2.8L III USM has two large-diameter double-surface GMo
lenses and a ground aspherical lens to decrease distortion, curvature of field,
and astigmatism. Two UD lenses reduce chromatic aberration to give you the most
accurate color rendition and detail. Subwavelength Coatings (SWC) and Air Sphere
Coatings (ASC) eliminate flare and ghosting from reflected light. To protect the
front and rear lens surfaces from smears and fingerprints, the lens employs a
non-stick Fluorine coating.
Focus Mode Switch: A switch on the lens barrel lets you select
Auto Focus (AF) or Manual Focus (MF). Full-time Manual Focus allows you to manually focus with the focus ring, even while the lens is in AF
Ultra-Sonic Motor (USM): The lens is equipped with an
Ultrasonic Motor (USM) for silent, high-speed auto focusing.
Included Accessories: The following accessories are
included with the lens:
- EW-88D Lens Hood: The EW-88D lens hood helps to prevent stray light from entering
the lens to avoid unwanted glare from affecting your photos. When attached
to the lens, the lens hood adds approximately 1" to the overall length of
- LP1222 Soft Lens Case: The LP1222 soft lens case can
protect the lens and keep it clean.
