EF 28mm f/1.8 USM
Combine a fast f/1.8 aperture with
28mm wide-angle focal length, and add
Canon’s Ultrasonic Motor AF. The result
is this surprisingly affordable fixed focal
length alternative to wide-angle zooms
that’s idealfor low-light shooting.
Internal, rear-group focusing means the
front element never moves, so it’s easy
to use with filters and accessories. The
autofocus isvirtually silent, and full-
time manual focus is alwaysavailable.
EF 28mm f/2.8
The most affordable fixed focal length
wide-angle lens in the Canon EF line-up
continues to give benefitsdifficult or
impossible to find with zooms. The fast
f/2.8 aperture makesit easy to use in
lowlight, and provides a brightviewfinder
image in the camera. It focuses asclose
as 10 inches/0.25m without accessories.
And optically, it provides excellent
edge-to-edge contrast and sharpness
along with superior correction of linear
distortion, so straight lines in a subject
(such asarchitecture) remain straight.
EF 35mm f/1.4L USM

the standard lens for many photo-
journalists and others who value its

are stunning, even wide-open atf/1.4.
Solid construction, a powerfulring-type
USM for smooth and fast AF, and full-
time manual focusing make this a great
lens for film or digital shooters.
