We might see updates to both at PMA, given that Canon's last freshly baked goods came out dualie style and the veep said Canon would be dropping more stuff next year than they did this year. If you didn't already ask Santa for a new DSLR for Christmas, it might pay off to wait a tick to see what Canon's got up its sleeve. [Kamerabild via Photography Bay via Engadget]

Another note: If you're looking to spend all the way up to $800, the XT and D40's bigger brothers, the XTi and D40x, are both available with a lens for under $700 from Amazon, and Newegg's throwing in a free 1GB CF card and 60GB external hard drive with the XTi. You can't go wrong either way. [Laptop Mag]

Conclusions, after the jump.

After many pages of intricately detailed comparisons, Singleton seems to declare the competition almost a dead heat, depending on what features are most important to you. He lauds the dust control and image stabilization of the Sony camera, the color accuracy and high ISO dynamic range of the Canon, and the autofocus and build quality of the Nikon.

I like the fact that the image stabilization is built into the Nikon's lenses (and my dad has a huge collection of them), better on-board flash which I use a lot, and it has a more-comfortable grip, along with easy handling and precision construction. But that's just my opinion; I could be wrong. – Charlie White

Canon Rebel XTi vs. Nikon D80 vs. Sony Alpha A100 [DigitalCameraInfo]

If you're looking for better image quality, the Canon is the winner. If you're looking for quicker shot to shot speed or startup to shot speed, it's the Nikon. The Canon also had less noise and more dynamic range, but the Nikon performed better in low light. However if you've got troubles holding your camera still, the Sony is the winner in image stabilization. If you're looking for which camera looks the best (subjective), they anoint the Nikon as the king.

The Sony Alpha A100 is intended for buyers who don't plan to buy more advanced equipment soon. The Canon certainly could be, and the Nikon is not just an entry camera, it's an appropriate backup body for prosumers and pros on a budget.

Faceoff [Digital Camera Info]

The EOS 400D Rebel XTi is Canon's latest addition to the sub-$1,000 dSLR camera market. Technical improvements include an impressive 10.1 megapixels, 9-point autofocus, 3 frame-per-second image capture and 27-frame bursts. Add a self-cleaning image sensor, and the XTi looks like one hell of a camera. But while Canon was sleeping, the camera gods blessed consumers with the Sony A100 and Nikon D80 - two formidable opponents. Check out the results in our 4D bargraph and then hit the jump for our frankenreview: the best parts of every review blended into a succulent technosmoothie. – Mark Wilson

Imaging

"The 400D / XTi still delivers silky smooth images, is usable at its highest sensitivities and feels very responsive overall."
"What I am seeing is a new tone curve. Reds, yellows, and oranges seem to be slightly darker while blues seem slightly lighter. The tone curve seems to push shadows darker - but the detail remains."
"...the XTi's measured and visible image noise was significantly worse than that of the CCD-based Nikon
D80 for any given ISO speed."
"The XTi uses Canon's Digic II chipset rather than the newer Digic III, and I wonder if the company might
have been able to eke out better performance and noise suppression with the latter."
"Canon has been renowned for their clean high ISO results. And, the new 400D is looking very good from this perspective."
"Focusing performance under low light has been improved by 1 stop."
- Canons traditionally need a lot of light, especially without image-stabilizing lenses.

LCD

"The bigger screen, while long overdue, is also welcome."
"...the paper-white background gets distracting."
"It's easily visible under all but the very brightest conditions."
"...at the highest brightness settings...gamma is increased enough to make exposure hard to determine."
- Future so bright, you gotta wear shades.

What the Camera Needs

"There is still no spot metering."
"I couldn't avoid severe underexposures of a backlit subject with the available metering tools..."
"...the only thing which seems to be missing from the standard 400D XTi package is anti-shake."
"This will undoubtedly have potential buyers carefully weighing it up against the Sony Alpha A100."
- Anti-shake lenses add $$ to this budget dSLR.

Random

"The responsiveness of this camera makes taking a photo about as instinctive as blinking an eye."
"Sitting on top of the new sensor is another of the Canon EOS 400D Digital Rebel XTi's major improvements - a self-cleaning, sensor-sealing low-pass filter..."
"Ironically, my 400D/Rebel XTi came with the dirtiest-from-the-factory sensor I have seen yet. And no, the self-cleaning sensor didn't make a difference."

Conclusions

"Canon already had a great product with the 350D / XT, but rather than resting on its laurels has upped the ante and delivered a worthy successor."
"If you don't yet have an investment in any particular manufacturer's lens system and want this year's best model for less than $1,000, you might consider the Nikon D80."

The Rebel XTi aka the EOS 400D will run for $900 with a 18-55mm zoom lens for $800 for the body alone. Just a small upgrade from their Rebel XT, but still cool, nonetheless. (Pictures via Liveingroom.org – Travis Hudson
