Canon EOS Rebel XTi (body only, silver) Preview

CNET has previewed the Canon EOS Rebel XTi digital camera which is expected to be available to the buying public sometime next month. 'Three things differentiate the Canon EOS Rebel XTi from the EOS Rebel XT, and two of them are the sensor. Though the CMOS chip used by the XTi is the same size as the 8-megapixel version in the XT, Canon crams more pixels into the space to bump the resolution up to 10 megapixels--and claims the XTi will have an equal dynamic range and noise performance. In theory, it's possible. The company says it's improved the design of the microlenses that sit atop each photosite--the microlenses gather indirect light and focus it back on the sensor--as well as increased the size of the photosites.

The CMOS chip in the XTi will also be self-cleaning. Similarly to many other dSLRs, the low-pass filter layer vibrates when the camera powers off or on in order to shake dust away from the sensor; plus, there's an antistatic coating on the filter to repel the dust. Furthermore, a bit of adhesive surrounding the sensor is designed to grab the dust, keeping it from flying around the camera chassis. In addition to dust control, Canon has split the low-pass filter into two parts, effectively placing whatever dust does settle beyond the range of focus.'
