The World’s Largest Selection.

Canon offers the world's largest selection of autofocus lenses. Canon EF Lenses

are favorites of professional photographers and world-renowned for their optical

quality and endless versatility.

EOS Digital cameras accept

over 50 of these lenses,

from ultra wide-angle to

super telephoto, plus

fish-eye, macro and

tilt-shift lenses.

IMAGE STABILIZER

Canon’s Image Stabilizer (IS) technology makes

handheld photography possible in more low-

light situations than ever before. With IS lenses,

a special group of lens

elements automatically

shifts its position,

thereby compensating

for the shake and

stabilizing the image.

L-SERIES LENSES

Identifiable by a red ring around the outer

barrel, Canon’s L-series lenses are distinctive in

their performance through

use of optical technologies,

UD (Ultra-low Dispersion)

glass, Fluorite and

Aspherical elements and

Super Spectra Coating.

ULTRASONIC MOTORS (USM)

Canon developed the world’s first lens-based

Ultrasonic Motors (USM) that used ultrasonic

scillation energy. USM lenses are faster and

quiet

er th

an conventional motor driven autofocus

stems and draw minimal power from the camera.

EF-S LENSES*

Designed for Canon EOS Digital cameras featuring

APS-C sized sensors with a 1.6x conversion

factor

, Canon’s EF-S Lenses take advantage of

the sensor’s smaller size, resulting in

compact, lightweight designs and

optimized performance without

compromise. The EF-S

18-55mm f/3.5-5.6 USM

has an improved exterior

design and AF algorithm

to provide fast and

silent autofocusing.

DIFFRACTIVE OPTICS

Canon’s use of diffractive optics results in lenses

that are both high performance and more compact

than those with traditional refractive designs.

While conventional glass lenses’ elements disperse

incoming light, thereby causing chromatic

aberration, Canon’s unique multi-layer diffractive

elements work together with conventional glass

optics to cancel the effects of dispersion and

minimize or eliminate chromatic aberration.

Performance

on the Move

In tennis and digital technology,

performance is about moving forward

to meet the next challenge. Both Canon

and Maria Sharapova excel in raising

their game to the next level – turning a

challenge into an opportunity to shine.

Canon’s superior digital technology

not only smoothes the way to flawless

everyday performance, but gives you

the power to do things you never even

dreamed of, putting your creativity at

center court, ready for all the world to see.
