Unleash Your Creativity

with EOS SLR Cameras.

Image

Processor

Developed to maximize perform-

ance between capturing and

recording stages of digital pho-

tography, Canon's DIGIC Image Processor chips

use advanced signal-processing techniques to

dramatically enhance image quality and deliver

a more intuitive, responsive camera. The latest-

generation DIGIC Image Processors work in

concert with Canon's CMOS sensors to achieve

even higher levels of performance. Signal pro-

cessing algorithms work with the multichannel

signal from the sensor and the high-speed DDR-

SDRAM buffer to deliver significantly improved

camera response. Power consumption has been

further reduced for even longer battery life.

CMOS Sensor

Taking advantage of its

own proprietary tech-

nologies, Canon develops

and produces its own

CMOS sensors. It fulfills the primary functions of

an imaging sensor – sensitive, accurate, noise-

free capture of image data – with unprecedented

performance. Unlike CCD sensors, CMOS sensors

convert and amplify signals before they are

transferred to the image processor, enabling them

to produce exceptionally clean image data and

reduce power consumption by as much as 90%.

Developed in three sizes (Full-frame, APS-H and

APS-C), they incorporate the latest in CMOS

engineering advances, significantly reducing

digital noise and expanding the useful ISO range.

Canon Digital Trinity

Canon's CMOS sensor captures images with exceptional

clarity and tonal range. Canon's DIGIC Image Processor

dramatically enhances image quality and speeds up all

camera operations for intuitive operation. The sensor and

processor work in concert with Canon's superlative EF and

EF-S lenses, forming the ultimate Digital Trinity.

EF Lenses

With nearly 60 EF lenses, the EOS System boasts

one of the world's most comprehensive selection

of autofocus lenses. All EF lenses feature

Canon's advanced optical technology, offering

quality, breadth and scope to photographers

everywhere. L-Series lenses have a reputation

in the professional photography world for

remarkable performance. Their lens construction

typically includes UD (Ultra-low Dispersion) glass,

fluorite or aspherical elements coated with

Super Spectra Coating for incredible clarity and

brilliant colors. EF-S lenses were developed for

EOS SLRs with APS-C size sensors. Lightweight

and compact, these lenses take advantage of the

sensor's size to deliver optimized performance

without compromising image quality. Specialty

lenses are also available such as macro, fisheye

and tilt/shift lenses.

Optical Image

Stabilizer

To help prevent blurred

images when shooting in

low light or at slow shutter speeds, many EF

lenses are equipped with Optical Image Stabilizer

technology that corrects camera shake by shifting

a lens group to realign the image on the imaging

sensor or film. Other systems are limited by

how far they can move an image sensor, and as

a result, their stabilization is less effective when

with Optical Image

Stabilizer

EOS SLR Technology

telephoto lengths get longer. Also, with Optical

Image Stabilizer you can see it working right in

the viewfinder – impossible with some other

stabilizer systems.

Full HD Video

The EOS 5D Mark II is the first

EOS Digital camera to offer

recording of Full HD video in Live View Mode.

And the advantages move way beyond the ability

to shoot on your SLR—the wealth of high-speed

lenses and shooting accessories that make

EOS photography so remarkable can also be

used in shooting video. To see the HD video

and photos on your HDTV directly from the

camera, simply connect the camera and TV with a

mini-HDMI cable.

EOS Integrated

Cleaning System

Using ultrasonic vibrations

to remove dust, the Self Cleaning Sensor Unit

combats stray dust that can enter the camera

when changing a lens or when out in the field.

In addition, any dust missed by the cleaner can

be removed by Canon's

Dust Delete Data

Detection software. This

combination of hardware

and software technologies

ensure a dust free

image.

EOS System

Accessories

The EOS System is unrivaled in

its comprehensive array of

accessories, ranging from battery

grips to focusing screens to

remote controls, that enhance

power, customization and versatility.

Also, EOS cameras and EX-series Speedlites

work in tandem to deliver great exposures and

automatic balanced fill-in-flash.
