AdrianWarren.com: Reviews: Canon EOS 400D
The Canon "consumer" digital SLR line began in 2003 with the launch of the EOS 300D/Digital Rebel, which was the first affordable (<1000USD) mass market dSLR. Whilst it was a breakthrough product in many ways, it was also a limited product; to many it was seen as a "crippled" EOS 10D due to the relatively large number of missing features from the otherwise similar EOS 10D. When Canon launched the EOS 350D/Digital Rebel XT, they were keen to break this perception. The EOS 350D was in many ways all the things the EOS 300D should have been, and it had the advantage of a newer 8MP sensor and faster chipset (DIGIC II).
Whilst being similar to the EOS 350D, the EOS 400D/Digital Rebel XTi brings some new features to the table. Amongst those new features is an integrated dust management system, a better AF subsystem (borrowed from its big brother the 30D), a higher resolution sensor, a larger buffer for improved burst performance, and controversially a larger single LCD display to replace the standard colour display and the simple settings display of previous models.
