18.0 Megapixel CMOS Sensor

The EOS 7D features a superb, Canon designed, 18.0 Megapixel

CMOS sensor that captures a tremendous level of resolution with

striking detail down to each individual pixel. With size to spare,

it's easy to crop images or to make massive enlargements without

concern of losing detail. A marvel of technical innovation, the

EOS 7D's CMOS sensor incorporates a number of significant refine-

ments that enhance the performance and speed in the capture of

each image. Thanks to an advanced, new, in-house semiconductor

CMOS Sensor (actual size)

manufacturing process, the EOS 7D's sensor has more pixels than any other

APS-C sized sensor in Canon's lineup, with less digital noise, a higher ISO

sensitivity, plus a wider dynamic range than previously available. The

EOS 7D's CMOS sensor incorporates a unique on-chip noise reduction

technology to deal with both fixed pattern and random noise. It features

a new photodiode construction that results in an improved photoelectric

conversion rate. The speedier conversion means faster and increased

sensitivity at the pixel level. This speed and sensitivity, in combination with

new gapless microlenses, plus less space between microlenses and photo-

diodes, means a better signal-to-noise ratio, which translates to outstanding

real-world performance. Finally, an infrared, multi-layer low-pass filter is

placed in front of the sensor to isolate and eliminate false colors that the

sensor may detect, while retaining full detail. This low pass filter features

a fluorine coating to reduce dust adhesion for less digital clean up.

Dual DIGIC 4 Image Processors

The EOS 7D's new Dual DIGIC 4

Image Processors ensure that

images are captured, processed and saved

with remarkable speed—up to 8.0 frames per

second! Developed and produced for Canon

cameras to maximize performance for both

the capture and recording stages of digital

photography, Dual DIGIC 4 Image Processors

Dual DIGIC 4 Image Processors

work in concert with Canon's CMOS sensor

chips to dramatically enhance image quality and deliver a more intuitive,

responsive camera. Optimized signal processing algorithms work with

the multi-channel signal from the cameras sensor to deliver significantly

speedier camera response. Color reproduction, noise reduction in low light

situations and reproduction of fine detail are also improved. These Dual

DIGIC 4 Image Processors speed up all camera operations such that a num-

ber of inventive shooting and recording features are possible. Live Face

Detection AF, HD Video, Canon's amazing

Auto Lighting Optimizer, Lens Peripheral Illumination

Correction and more are all possible thanks to the speedy processing of

the Dual DIGIC 4 Image Processors.

Professional Level Performance

Capable of shooting up to 126 Large/JPEGs with a UDMA CF

card at 8.0 fps, the EOS 7D is a perfect camera for action.

The EOS 7D is outfitted with a rugged, remarkable shutter, which, aided by

the Dual DIGIC 4 Image Processors, ensures instant response and perform-

ance on par with most professional cameras on the market while outpacing

every camera in its class.

Shot at 8 fps

The EOS 7D has a broad range of ISO settings, up to ISO 12800 in H mode,

enabling shooting from dawn through dusk and ensuring capture of the

finest detail. The Canon CMOS sensor and Dual DIGIC 4 Image Processors

ensure that shooting in poor lighting situations is as easy as point and

shoot. The EOS 7D employs a 14-bit converter to process the output of

the CMOS sensor. Compared to the 12-bit converters used in most digital

cameras, Canon's design ensures smoother tonal transitions, more natural

gradations, and superior color fidelity. RAW images are recorded at 14 bits

so that processed 16-bit TIFF images contain the full range of tonal values

captured by the sensor.

Media Creation

Beyond the Still,

Canon Full HD.

A Complete Media Creation Tool

The EOS 7D does not just shoot video clips, it offers the

enhanced image quality, smooth frame rates and adaptive

exposure compensation necessary in a professional movie making tool.

Shooting video with the EOS 7D increases flexibility for the photographer

in that it also allows for full use of Canon's EF and EF-S lenses, including

wide angle, macro, tilt-shift and fish-eye, providing a wealth of depth-of-

field and other creative

shooting options once reserved

only for still photography. By

shooting video with a large

sensor camera, it's simple to

take advantage of the image

quality and characteristics

intrinsic to SLR photography.

Combined with its size, image

quality and flexibility, the

EOS 7D is an all-in-one image

capturing tool. Not only can

one take advantage of the

EOS 7D's expansive range of

ISO sensitivities, for amazing

performance, even in dimly lit

situations, it's simple to exert

full control over exposure and depth-of-field, which can have a profound

effect on the mood of the moving image. And it's all as easy as the press

of a button. The EOS 7D has a dedicated Live View/Movie Recording lever

with a start/stop button that gets the shooting started fast.

Recording Sizes

Full HD Video is captured at 1920 x 1080 resolution at 24 (23.976), 25, or

30 (29.97) fps, for up to 4GB per clip. Movies are saved as MOV files and

can be viewed in Full HD with HDMI output. Other recording sizes include

HD at 1280 x 720 resolution at 50/60 (59.94) fps or SD/VGA at 640 x 480

resolution at 50/60 (59.94) fps.

Manual Exposure Control

As with still images, the more control the photographer or filmmaker has

over the technical aspects of a shoot, the more refined the expression, or

mood of the final product. The EOS 7D offers completely flexible exposure

control for its movie modes, allowing for complete creative control for the

shooter. In Manual mode, users can control depth-of-field and sense of

motion, creating gorgeous background blur. Exposure can be determined

and set even in complex

lighting situations, maintain-

ing the same look and feel

through an entire scene, not

just the initial shot, and

minimizing camera noise that

can occur when the aperture

changes due to exposure

adjustment mid-clip.

Beyond the Moving

Image

The EOS 7D has a built-in

microphone for simple mono

recording. For sound quality

that mirrors the tremendous

resolution of the EOS 7D's

video recordings, stereo sound can be recorded through an external micro-

phone connected to the EOS 7D's 3.5mm microphone input terminal. With

an external microphone attached, the possibilities for sound recording are

increased exponentially. Another phenomenal perk of the EOS 7D's Movie

mode is that still images can be captured, in full resolution, while shooting

movies and can be saved as distinct files. It's as simple as pressing the

shutter button while recording a movie, and the supplied image can be

modified as could any other recorded still. Playback modes are available

in-camera. Sound and all Live View AF features can be used in shooting

video. Simple editing can even be done in-camera, and movies can be

played on both standard and HD televisions by using an AV

cable or HDMI. Uploads to a computer are straight-

forward and quick.
