The Canon EOS Rebel XSi DSLR, also known as the 450D, is an entry level digital SLR which is part of the EOS Rebel line of digital cameras. Released in April of 2008, it is another continuation of the successful line of Electro-Optical System cameras that feature auto focus capabilities. The series was originally introduced in 1987, and this latest version is a digital single lens reflex camera.

Also known as the 450D overseas, the 12.2 megapixel camera includes a 3-inch LCD and a new CMOS sensor that allows enhanced ISO sensitivity. The camera uses Canon's DIGIC III processor with a 14-bit A/D converter. Canon has also introduced SD cards to the equation for the first time on one of their DSLR line of cameras. The suggested retail price is $800, extra for the zoom lens. With the recent introduction of the T1i in 2009, the XSi has been discounted and the kit version had a rebate offer from Canon in July 2009.
