This is an old camera, still a good one, but we recommend that you go with an updated model like the Digital Rebel T1i/500D. Here's what we had to say when the XTi was released in August 2006:
The Canon Digital Rebel XTi (a.k.a. 400D) is the successor to the ever-popular Canon Digital Rebel XT/350D. Canon has made every effort to continue the affordability and power of the Digital Rebel line by bringing the 400D up to the 10 megapixel level, and introducing important features from their line of professional dSLRs. The Digital Rebel is a unique opportunity for curious and adventurous photographers to graduate from mainstream cameras and into the upper echelons of photography without getting too deep into unfamiliar territory or spending an exorbitant amount of money. The body-only model of the XTi/400d will cost only $799, with the lens-included model coming in at around $899.
The nine-point auto focus (a feature it shares with the 30D) provides faster, more accurate photos, and the 2.5-inch LCD is a marked improvement over the previous version's measly 1.8-inch display. For current XT/350D owners, the XTi/400D is an attractive upgrade, and for those who haven't yet graduated to prosumer digital cameras, this is the perfect opportunity. Don't hesitate, the Digital Rebel will change the way you take photos.
Note: This is the "body only" version of the Digital Rebel XTi. It does not come with a lens. For a lens-equipped version, click here.
