The Canon EOS Digital Rebel XTi has a newly designed 10.1 MP Canon CMOS sensor plus a host of new features including a 2.5-inch LCD monitor, the exclusive EOS Integrated Cleaning System featuring a Self Cleaning Sensor and Canon's Picture Style technology, all in a lightweight, ergonomic body. The EOS Digital Rebel XTi is compatible with all Canon lenses in the EF lineup, ranging from ultra-wide angle to super telephoto lenses, and including Canon's EF-S series lenses, manufactured specifically for Canon's APS-C sized digital sensor. Canon's Speedlite 430EX is perfectly suited to the EOS Digital Rebel XTi. In addition to Canon's EF lenses and Speedlite flashes, many other accessories are designed by Canon to work perfectly with the EOS Digital Rebel XTi.
