Canon EOS 400D / Digital Rebel XTi

Canon has today announced the latest evolution in their affordable digital SLR series, the ten megapixel EOS 400D / Digital Rebel XTi. Headline new features / specifications include the ten megapixel CMOS sensor (up to ISO 1600), a new dust reduction system, nine area auto focus, Picture Styles, a large 2.5" LCD monitor which now also provides shooting information (the second control panel LCD is gone) and better continuous shooting buffering.

MAIN FEATURES

10.1 - Megapixel CMOS sensor
Newly developed by Canon, this large CMOS sensor is at the top of its class with 10.1 million effective pixels. A wide ISO speed range and low noise are realized through innovations like redesigned microlenses and enhanced output amp performance. On-chip noise reduction automatically engages when noise is detected (“Auto”), and can be engaged for exposures of 1 sec. or longer (“On”). Also designed for the EOS 400D DIGITAL are new automatic cleaning functions that reduce dust throughout the sensor unit to assure image clarity.

DIGIC II imaging engine
DIGIC II, Canon's exclusive imaging technology, processes large amounts of data from the APS-C size CMOS sensor at high speed to deliver images of exceptional definition and smooth gradations. Color reproduction is quite natural, false colors are reduced, and white balance is highly precise. This refined imaging system contributes to user-friendly operation in any lighting situation while keeping power consumption minimal.

2.5-inch LCD
Offering improved viewing and operability, the EOS 400D DIGITAL has a 2.5-inch TFT LCD color monitor with approximately 230,000 pixels to accommodate large fonts in menus and a remarkable viewing angle of 160°. Picture quality and brightness are therefore equally maintained from almost any viewing angle — front and center or upward angle. Brightness is now yours to command in seven levels, with the highest even surpassing that of professional models. Such variable display enables easy image verification in bright outdoor settings as well as low-lit interiors, right after shooting.

EOS Integrated Cleaning System
To assure fine photo results, Canon employs dust-resistant materials and structures to dramatically reduce dust generation within the EOS 400D DIGITAL. Measures also are taken to prevent dust from adhering to the sensor due to static electricity. A remarkable new function is the Self Cleaning Sensor Unit that actually vibrates the low-pass filter to remove dust particles from it. Additionally, by targeting image data for leftover dust after cleaning, the Dust Delete Function within the bundled software can be used after shooting to remove dust spots that may remain on the captured image. For photos that are consistently distinct and clear, this dust reduction system is essential.

Self Cleaning Sensor Unit
Unwanted shadows on photos can be caused by dust that isn't actually on the sensor but on the low-pass filter (LPF) in front of it. Though cleaning can be manually selected by menu, automatic cleaning by ultrasonic vibration of the LPF is activated for about one second when the power is turned on or off. As shooting priority occurs on start-up, pressing the shutter button disables the self-cleaning operation and returns the camera to shooting mode. Dust falling off the filter during cleaning adheres to the sticky material of the retaining component at the LPF base.

9-point AF
For smooth operation and flexibility needed for creative expression, the EOS 400D DIGITAL has a 9-point AF sensor that enables fast and high-precision focus detection plus enlarged subject coverage. Convenient cross keys provide fast and easy AF point selection. For more accurate shooting and additional flexibility, focusing points are in a diamond-shaped layout with a central AF point offering cross-type focusing, regardless of lens brightness. In addition, higher precision focusing is possible when using lenses brighter than f/2.8. Such variable focusing enables quick adjustment for a variety of compositions and shooting situations.
