10.1 Megapixel APS-C Size CMOS Sensor
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 (22.2 x 14.8mm) 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. With an effective pixel resolution of 3,904 x 2,598, the EOS Digital Rebel XTi offers superb detail and clarity, even in large prints, and generates finished files that open at approximately 30MB in your image-editing software. On Canon's CMOS sensor, each pixel is captured with fine detail to create images of tremendous depth and resolution, ensuring enough information for even poster-sized prints.

DIGIC II Image Processor
The EOS Digital Rebel XTi is the product of Canon's extensive in-house development: The DIGIC II Image Processor was designed specifically for Canon digital SLR cameras and enhances every aspect of image capture. Information captured by the CMOS sensor is processed and assembled into images of exceptional quality. With the DIGIC II Image Processor on board, photographers can expect natural color reproduction, precise white balance in any number of lighting situations and unparalleled clarity. The DIGIC II Image Processor employs sophisticated signal processing algorithms and works at greater speeds, all while consuming less energy.

Large 2.5-inch LCD monitor with wide viewing angle.
The EOS Digital Rebel XTi has a brilliant 2.5-inch LCD monitor with approximately 230,000 pixels. All shooting and review information is accessed on the rear LCD monitor, and the wide viewing angle of 160 and brighter, easier-to-read menus give the new Rebel XTi LCD monitor an obvious advantage.

Display Off Sensor
When composing images, the Digital Rebel XTi's external display turns off automatically thanks to the newly developed Display Off Sensor. This new sensor detects the photographer's face against the back panel of the camera, and turns the screen off to prevent the LCD monitor's brightness from disturbing the photographer's eye while looking through the viewfinder.

Speedy Operation
With a startup time of 0.2 seconds, the EOS Digital Rebel XTi is ready to go the instant it's brought to the eye. And the Digital Rebel XTi's shutter can record images as fast as 1/4000 seconds and as long as 30 sec., plus bulb at up to 3 fps for 27 consecutive shots. It synchronizes with Canon Speedlites at 1/200 seconds.

9-Point AF
The EOS Digital Rebel XTi has a high-precision 9-point AF system for speedy and accurate focusing in any situation. Conveniently located on the back of the camera for thumb-controlled action, Canon's cross key buttons enable instant choice of the 9 focus points, or allow the camera to choose them automatically. One-Shot is perfect for still photography. AI Servo AF tracks moving subjects, ensuring accurate focus. AI Focus AF switches between One-Shot and AI Servo when subjects are moving and stopping. The Digital Rebel XTi's focusing system functions in metering ranges of EV-0.5 to 18, and displays information on the Digital Rebel XTi's big LCD Display.

"Picture Style" settings
With Picture Style technology and the EOS Digital Rebel XTi, photographers can recreate characteristics of their favorite films. Color, saturation, sharpness and contrast settings create noticeable variation in the saved image. In addition to six preset Picture Styles (Standard, Portrait, Landscape, Neutral, Faithful and Monochrome), users can create three additional settings for their particular photographic style.

Print/Share Button
Printing and uploading to a computer is incredibly simple with the Digital Rebel XTi's Print/Share button. By connecting the Digital Rebel XTi to a computer via the USB 2.0 port, it's easy to transfer some or all of the photographs in the cameras memory to folders on the computer.

Self Cleaning Sensor Unit
To combat against stray dust that enters the camera and adheres to the image sensor during a lens change, the Digital Rebel XTi features an all-new, Canon-designed Self Cleaning Sensor Unit. The low pass filter cleans itself automatically with ultrasonic vibrations, removing dust from the sensor assembly.

Canon EOS Digital Solution Disk Software (Version 13.0)
The EOS Digital Rebel XTi comes bundled with the updated Canon EOS Digital Solution Disk (Version 13.0), which features powerful software programs designed to extend the EOS experience to the computer. These include Canon's ZoomBrowser EX for Windows (Version 5.7), ImageBrower for Macintosh OS X (Version 5.7), Digital Photo Professional (Version 2.2), Canons EOS Utility (Version 1.1) and PhotoStitch (Version 3.1). Each application is designed to perfect captured images, and streamline the digital workflow.

Digital Photo Professional (Version 2.2) is an image processing program that enables high-speed RAW image processing, high-speed previewing for real-time image adjustment and support for sRGB, Adobe RGB and Wide Gamut RGB color spaces. Because its CMS (Color Management System) compatible, Digital Photo Professional allows for easy image layout and printing in Adobe RGB in conjunction with Easy-PhotoPrint and PictBridge printers. It also features the Digital Rebel XTis Dust Delete Data Detection tool for cleaner images.

EOS Utility (Version 1.1) for Macintosh or Windows handles the connection between the camera and computer, whenever theyre connected via USB. It allows remote controlled shooting from the computer, handles downloading of images from the camera to the computer, and allows seamless linking to either Canons ZoomBrowser/ImageBrowser or Digital Photo Professional software once images have been copied to the hard drive. Furthermore, its used to upload settings back into a USB-connected camera.

ZoomBrowser EX (Version 5.7) for Windows and ImageBrowser (Version 5.7) for Mac OS X are the easy, user-friendly options for viewing and editing of JPEG and even RAW image files. Both allow viewing of numerous types of images including finished TIFF and BMP files. Both also have a variety of search options for finding images, allow re-naming of single images or batches of files, and offer a variety of options for printing without using a separate image-editing program.
