The Canon Digital Rebel XTi /EOS 400D is the third iteration of the company’s entry level DSLR. The changes over the Canon Digital Rebel XT / EOS 350D are mainly in the sensor — increased to 10 megapixels — and moving the camera information read-out from the top panel to the main LCD screen.
As we expect from Canon the high ISO images are practically noise-free. The only disappointment we had was with auto white balance — the camera does not handle incandescent light well.
The Canon EOS 400D has an automatic routine for removing dust from the image sensor filter similar to that used by Olympus. In this case the filter is ultrasonically cleaned when the camera is turned off. The responsiveness of this camera makes taking a photo about as instinctive as blinking an eye. The shutter release is nicely damped and the mirror/shutter slap is reasonably restrained even if not as quiet as we would like.
