The new 12.2-megapixel EOS Rebel XSi camera incorporates a number of high-end functions and technology found in
Canon's professional SLR models, the EOS Rebel XSi camera boasts an improved
autofocus sensor, enhanced 14-bit A/D conversion, an advanced Live View
function, and the proprietary DIGIC III image processor. When paired with any of the more than 60 compatible Canon EF and EF-S lenses, including optically image stabilized EF-S lenses like the EF-S18-55mm f/3.5-5.6 IS - now included in the EOS Rebel XSi kit
- or the new EF-S55-250mm f/4-5.6 IS, the EOS Rebel XSi DSLR delivers images
that will delight and inspire family and friends at an entry level price tag.
Luxury Feel and Function
At first glance, one
notices the Rebel XSi's large, 3-inch LCD monitor, enhanced from the 2.5-inch
screen on the Digital Rebel XTi model. The larger 230,000 pixel screen makes it easier for users to review images and scroll through the Rebel XSi camera's menus. The larger-sized display provides the ability to use a larger font size for menu text, making it easier than ever to read settings and options. The new screen also features a broadened color gamut, seven brightness settings for easy viewing under a variety of shooting conditions and a wide viewing perspective in all directions.
The EOS Rebel XSi camera
features a substantial yet streamlined profile, with curved edges, contoured
surfaces, conveniently placed controls and comfortably constructed rubber grip
and thumb rest that all contribute to fatigue-reducing hand fit. The camera body is constructed of a rugged
yet lightweight combination of stainless steel and polycarbonate embedded with
glass fiber.
Improved Image
Quality
At the heart of the new EOS Rebel XSi is its newly
designed 12.2 megapixel APS-C size Canon CMOS sensor. This new sensor employs large microlenses over each pixel to reduce noise and enhance sensitivity up to ISO 1600, which is
ideal for high-quality images in low light. The APS-C size sensor retains a 1.6x focal length conversion factor compared to full-frame digital image sensors or 35mm film format cameras.
Another image quality enhancement is the
upgrade of the Analog-to-Digital (A/D) conversion process to a 14-bit A/D
processor. The inclusion of the 14-bit A/D process means the Rebel XSi camera records up to 16,384 colors per channel and allows the camera to produce images with finer and more accurate gradations
of tones and colors. This is ideal for shooting outdoors where subtle hue
changes in sky, water or foliage can really add to an image.
The Canon EOS Rebel XSi
DSLR also incorporates the optional Highlight Tone Priority and High-ISO Noise
Reduction functions first introduced in 2007 with the EOS-1D Mark III
Professional Digital SLR and now available for the first time in an entry level Canon digital SLR camera. Additionally, the new camera is equipped with Canon's Auto Lighting Optimizer technology, which corrects image brightness and contrast automatically. Introduced last year
in the EOS 40D camera, this valuable optional feature now works in all exposure
modes and utilizes Face Detection technology to prevent underexposure with
backlit faces.
DIGIC III Image
Processor
If the 12.2-megapixel APS-C size CMOS sensor is the heart
of the camera, then Canon's DIGIC III processor is the brain. The latest
generation of Canon's proprietary image processing engine, DIGIC III technology
ensures that the fine details and natural colors of the images are optimally
recorded. The DIGIC III processor also
manages the camera's efficient energy consumption and high-speed signal
processing performance. The EOS Rebel XSi is the first model in the Rebel series to incorporate DIGIC III.
Enhanced Live View
Introduced in 2007 on
the EOS-1D Mark III DSLR, this function makes its debut in an entry level Canon
DSLR with the EOS Rebel XSi camera. Live View allows users to frame shots
through the LCD screen rather than the viewfinder. Going beyond the manual focus
and phase-detection AF capabilities of earlier EOS models with Live View, the
EOS Rebel XSi camera adds a new 'Live Mode' contrast-detection AF function that allows the camera to focus automatically during Live View without lowering the
reflex mirror.
Improved Autofocus and Framing Rate
The EOS Rebel XSi Digital SLR utilizes a precise
nine-point Autofocus (AF) system featuring a newly developed AF sensor that
improves the camera’s subject detection capabilities compared to earlier
models. The new Rebel XSi DSLR provides a cross-type AF measurement at the center that’s effective with all EF and EF-S lenses, while providing enhanced precision with lenses having maximum apertures of f/2.8 or faster. The cross-type AF
measurement reads a wider variety of subject matter than conventional
single-axis AF sensors and thus increases the new camera’s ability to autofocus quickly and accurately. The EOS Rebel XSi is also the fastest firing Rebel model to date, capable of continuously capturing 3.5 frames per second for bursts of up to 45 images in large/fine JPEG mode and 6 frames in RAW mode. The faster frame rates and finer focusing capabilities of the Rebel XSi together with its impressive image burst rate will help photo enthusiasts preserve family milestones or capture split second sports action at just the right moment.
EOS Integrated Cleaning
System
The new Rebel XSi DSLR utilizes Canon's EOS Integrated Cleaning system, first introduced on the EOS Rebel XTi camera. The camera's Self-Cleaning Sensor Unit shakes dust particles off of the low-pass filter in front of the sensor. The dust is then trapped by an adhesive along the base, preventing it from causing further nuisance. Cleaning is engaged each time the camera is powered up or shut down or manually through the "clean now" function.
The second part of the cleaning system involves post processing with a compatible personal computer and
the supplied Digital Photo Professional software. Here the camera maps any spots that may remain on the sensor, saving it as Dust Delete Data and subsequently subtracting dust spots from the final image during post processing. A third option includes
a manual sensor cleaning function which raises the mirror and allows users to
clean dust that may have stuck to the low-pass filter.
Back to the Basics
In keeping with its EOS system heritage, the new Canon EOS Rebel XSi camera is equipped with a host of useful creative controls, including shutter speeds ranging from 1/4000 sec. to 30 sec. plus Bulb, a choice of four metering patterns including 4% spot metering (another first for the Rebel series), a wide range of exposure modes from fully automatic to fully manual, depth of field preview, mirror lock and much more. The new camera is fully compatible with all Canon EF and EF-S lenses, as well as EX-series
Speedlites, an optional Battery Grip, and remote control and viewfinder
accessories.
A departure from previous EOS Digital Rebel models, which accommodated CF type memory cards, the new EOS Rebel XSi camera utilizes SD and SDHC memory cards including those with capacities higher than 2GB, making it the perfect upgrade for users already equipped with SD cards from point-and-shoot model cameras. Additionally, the EOS Rebel XSi camera utilizes Canon’s new high-capacity LP-E5 lithium ion battery
pack, which provides 50% more exposures per charge than earlier models with virtually no increase in size or weight.
In the
Box
Shipping in April 2008 the Canon Rebel XSi camera is available in body-only configuration which includes a rechargeable battery pack and charger, USB and video cables, a neckstrap, an EOS Solutions Disk CD, and a 1-year Canon U.S.A., Inc. limited warranty.
