Huge Sensor for Tremendous Photographs
Superb image quality: 10.1 Megapixel CMOS Sensor, extensive noise reduction technology, and 14-bit conversion for outstanding color tones and gradations.
|
| Canon's large-area CMOS (complementary metal oxide semiconductor) sensor captures images with exceptional clarity and tonal range, and offers the most pixels in its class. This APS-C size sensor (22.5 x 15.0mm) has the same 3:2 ratio as film cameras, enabling an effective angle of view that is 1.6x the normal EF Lens focal length. 14-bit A/D conversion means fine transitions from light to dark tones, and a significant drop in digital and shadow noise. The EOS 40D has an extensive ISO range (from 100 to 1600, plus ISO 3200* in extended mode) which is selectable in 1/3 stop increments. The EOS 40D's CMOS sensor uses much of the new technology first seen in the EOS-1D Mark III camera. New manufacturing techniques mean each pixel is more sensitive to light, and less area between pixels is wasted on the sensor. The on-chip noise reduction electronics are also entirely new, and combine with the sensor's general design for less digital noise and better high-ISO performance than ever before. This results in larger, clearer, sharper and more detailed photographs right from the start.* Standard output sensitivity. Recommended exposure index.

Developed to maximize performance between the capture and recording stages of digital photography, the EOS 40D's DIGIC III processor is faster and more powerful than ever. The latest-generation DIGIC III Image Processor works in concert with Canon's CMOS sensor to achieve even higher levels of performance. The entire electronic system is totally re-designed, giving the camera its incredible combination of speed and image quality. Digital noise is significantly reduced in shadow areas, and color reproduction is superior.
Dual "DIGIC III" Image Processors
The EOS 40D is one of the fastest digital SLRs offered at this price. It shoots up to 6.5 fps, making it ideal for everything from wildlife to sports. It can capture up to 75 JPEGs, or 17 RAW images in one burst. Whether it's the 0.15-second startup time, the high-speed mirror drive, the brief shutter lag time (only 59 msec), or the predictive AF focusing for capturing the action, the EOS 40D will amaze and delight photographers who don't want to wait for their camera when they're ready to shoot.

Sharp, Fast Focus, No Matter the Light
New AF system with 9 cross-type sensors, and world's first diagonal high-precision cross-type AF at center point with f/2.8 and faster lenses. |
The EOS 40D takes some of the most advanced features from Canon's professional cameras and incorporates them into its design. It has a newly designed, high-precision 9-point wide area AF that uses cross-type points with lenses f/5.6 or faster, enabling the camera to focus faster, more accurately, and in ever more complex lighting. Each of the nine AF points has this cross-type coverage, a first in Canon AF SLRs. Adding to this AF performance, the 40D incorporates a diagonally mounted, high-precision cross-type sensor at the center AF point that is sensitive to both vertical and horizontal lines when fast lenses (f/2.8 or faster) are used, for for added accuracy and precision with these wide-aperture lenses. It's the world's first AF SLR where both lines of a cross-type sensor offer high-precision AF coverage. All focus points can be chosen automatically, or accessed using the 40D's intuitive, thumb operated Multi-Controller.

The Promise of Perfect Images
EOS Integrated Cleaning System, Picture Style settings, Spot metering, and Highlight Tone Priority for advanced in-camera image control. |
EOS Integrated Cleaning System
Photographers who must change lenses in dusty environments will find the advanced Canon EOS Integrated Cleaning System a tremendous time saver. Dust that settles on the sensor surface is removed using ultrasonic vibration. This Self Cleaning Sensor Unit routine is automatically activated whenever the camera is powered on or off. (It can also be manually activated.) A special collar positioned around the sensor collects the loosened dust. Dust particles can also be automatically removed via software. By shooting a plain white subject, the photographer can acquire dust position data that is transmitted along with the image (whether JPEG or RAW). Canon Digital Photo Professional (DPP) version 3.1 or higher software can then be used to manually or automatically erase the dust spots. It's not one feature, it's a built-in system to minimize the effect of dust in high-resolution digital images.
Self Cleaning Sensor Unit
A key element of minimizing dust is preventing it from clinging to the front surface of the imaging sensor. To combat against this, the EOS 40D features a Canon-designed Self Cleaning Sensor Unit. The low-pass filter at the front of the sensor shakes off dust automatically with ultrasonic vibrations, removing dust from the sensor assembly.

Dust Delete Data Detection
Dust that may still remain on the front of the sensor can also be erased with software included in Digital Photo Professional (DPP) Version 3.1 or higher. A simple test shot of a plain, white object can be taken, using a menu setting. This Dust Delete Data image is analyzed in-camera, and the location and size of any remaining dust is added to any subsequent pictures taken. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon's DPP version 3.1 and up. This added software option ensures the cleanest possible image, perfect for printing or archiving.

Spot Metering
The EOS 40D also includes a spot meter function that measures roughly 3.5% of the center of the image.This new metering function, added to Canon's impressive Evaluative, Center Weighted averaged and Partial-metering modes, gives the photographer even more choices for custom-tailored shooting.
Highlight Tone Priority
This vital Custom Function lets photographers get even better detail in bright highlights, even in contrasty lighting conditions. It's beneficial for nearly any type of picture, from mid-day shots on a safari to portraits in sunlight, where a user may encounter bright highlight areas where he or she wants to preserve details. Finally, there's no impact on the camera's shooting speed or burst rate when Highlight Tone Priority is engaged. It takes full advantage of the EOS 40D's new 14-bit per channel conversion, meaning there are 16,384 distinct tones from darkest to lightest in each color channel.
