About this model
The Canon EOS 400D (also known as the Digital Rebel XTi) is a classic entry-level DSLR. Its 10.1-megapixel APS-C sensor delivers far better image quality than compact cameras, especially in low light, and the included EF-S 18-55mm f/3.5-5.6 II lens is a versatile standard zoom for everyday shooting. The 400D was Canon's first EOS to feature a dust-reduction system (EOS Integrated Cleaning System), which helps keep images clean. It offers a 2.5-inch LCD, 9-point autofocus, and shooting modes from fully automatic to full manual, making it a great camera for learning photography on a budget.
