Canon EOS Rebel XSi

The new update popular Digital Rebel XTi SLR: the EOS Rebel XSi. The XSi ups the resolution to 12.2 megapixels and includes improved autofocus, live view, an enlarged 3-inch LCD screen, and an optical image stabilized kit lens. The storage medium also changes to SD and SDHC memory cards; previous models used CompactFlash cards. The Digital Rebel XSi will cost $799 for the body and $899 for the kit with the 18-55mm lens, and will be available in April. As well as upping the resolution to 12.2 megapixels (from from the 10.1 megapixels of the Digital Rebel XTi), the XSi has a new and improved analog-to-digital converter. Canon claims it allows recording of up to 16,384 colors per channel, leading to better, more subtle colors. In addition, Canon has added micro-lenses over every pixel that focus the light, which Canon claims will lead to better low light performance. Although the resolution has increased, the size of the image sensor has not, so the lens conversion factor remains at 1.6. The Rebel XSi also includes a new DIGIC III image processor, previously seen on higher-end EOS models such as the 1Ds Mark III.
