EOS SLR TECHNOLOGY

The history of Canon EOS SLR cameras is brimming with examples of technological

innovations that have set new industry standards for performance and usability. And

yet, at Canon, technology is never an end in itself. Every technological advancement

must yield tangible benefits to the user. Does a new feature enable the camera to more

quickly and faithfully respond to the photographer's will? Does a new material or

process improve the camera's long-term reliability? Canon EOS advancements endure

because they enhance the photographic experience, whether

you are a seasoned professional or new to SLR shooting.

Put simply, Canon EOS SLR technologies are

impressive because of the quality of the images

they enable you to create.

Autofocus Technology

T he best autofocus system is comprised of the

ultimate combination of accuracy and speed. And

for that combination, there's nothing like the AF

systems found in EOS SLRs. With cutting edge

technical innovations, EOS cameras always feature

the latest in AF performance, raising the bar with

each successive camera introduction. Top EOS

SLR cameras use an extraordinary 45-point

high-density Area AF system that provides

not only a large AF coverage area, but also

the greatest range of control over focusing

point selection. The focusing point can be

selected automatically by the camera

(based on high-speed microcomputer

analysis of image content) or manually by

the user. Select EOS cameras feature up to

39 cross-type AF points that provide both

vertical and horizontal sensitivity, guaran-

teeing the same optimal performance no

matter the camera's orientation. To main-

tain focus, advanced Canon focus tracking

technology helps to retain the accuracy of

the initial AF setting, no matter how fast the

subject is moving. High-speed microcom-

puters use advanced algorithms that

ensure fast and accurate AF performance under

High-Speed Shooting

EOS SLR cameras have always been

associated with speedy operation.

Certain Canon EOS cameras offer 10

frames-per-second continuous shooting,

up to 28 RAW files or 121 full-resolution

JPEGs. Canon provides other aspects of

camera responsiveness as well: the

speediest EOS has a minimum lag time of

40 msec, an 80 msec viewfinder black-

out time (at speeds of 1/60th and

above), shutter speeds up to 1/8000

sec., and a flash sync as fast as 1/300

sec. when used with EOS Speedlites.

Dedicated, quiet low-speed modes and

self-timers add flexibility to speed.

Diverse AF Shooting Options

Beyond the AF modes supported in each EOS

camera, Canon developed a number of AF options

to further enhance customization and creativity.

Certain Canon models can register original AF

points' "Home Positions" and represent them in

both horizontal and vertical shooting positions,

suitable for shooting in situations where compo-

sitions are retained from shot to shot. For more

flexibility, the new Canon Zone AF system is

particularly useful when the subject is off-center.

One of five distinct focus zones can be chosen

and the optimal point can be selected from

there. In addition to these modes, certain EOS

cameras' AF systems can be further customized

via the Custom Function Menu. Parameters such

as initial focus point, AF beam control, AF zone

expansion, AF Stop and more can be selected and

refined to suit the photographer and the situation.
