The Canon EOS 400D also known as the Rebel XTi is one of the best DSLRs today. I am a armature photographer but yes I know my equipment well.
I wanted to upgrade my camera for a long time so did intensive research on the web before making my decision.
The Canon EOS 400D can do wonders to how you click pictures. The quality can be compared to any top end professional DSLR that was available a couple of years back.
The camera has some amazing features like a Internal sensor cleaning system as soon as you switch the camera on. The 10 mega pixel sensor is great and the camera gives you the power to shoot anything from an ant to an airplane even with the standard 18-55MM lens. The best part is that the camera is compactable with hundreds of Cannon lenses and some very cost effective 3rd party lenses. What I love about my Canon:- Everything to be true.
