To test the EOS 400D's USB speed we transferred approximately 200 MB of images (mixed RAW and JPEG) from a SanDisk Extreme IV 2 GB CF card (the same card used in the other readers).

The EOS 400D produced a consistent 8.4 EV of dynamic range from ISO 100 to 800, dropping to 7.8 EV at ISO 1600.

But when its predecessor-in this case, the EOS Rebel XT-was renowned for producing excellent, low-noise photos at a more-than-adequate 8-megapixel resolution, it's risky to replace it with a higher-resolution but potentially lower-sensitivity chip as Canon did with the EOS Rebel XTi.

If you don't change lenses that often, don't mind the smaller LCD, don't need the slight bump in continuous-shooting speed, and don't need the higher resolution, then you don't really need to pay extra for the Canon EOS Rebel XTi.

The Canon EOS Rebel XTi's LCD's status display is extremely useful and easy to read, and it provides a single place to change all the relevant settings.

As previously mentioned the EOS 400D now uses the LCD monitor for camera settings display during normal shooting, this automatically blanking if you raise your eye to the viewfinder.

Where the EOS 1000D scores highly is in final image quality, and especially in image noise control.

There is no difference in highlight range between the 1000D and the 400D with which it shares a sensor, so the improvement in the shadow range is probably down to increased noise reduction.

In our usual 30 second exposure test the EOS 400D produced only one or two 'hot pixels' which were easily taken care of with the optional long exposure noise reduction, which is in automatic mode by default.

The EOS 400D provides a wide range of control for image sharpening, contrast, color saturation and color tone.

My point and shoots NEVER survived in low light¡Kneedless to say I have fallen in love with my ¡§Rebel¡¨ and according to my husband, spend way too much time with ¡§her¡¨ ºIn my search for a good SLR that matched my budget, I chose the Canon Rebel Xti.

Despite my few complaints, the Canon EOS Rebel XTi still shoots some very nice photos, with good color rendition, broad dynamic range (when there's sufficient illumination), and accurate automatic white balance.

I find the Rebel XS fits comfortably in my hands, that the buttons are easily found,(and to me at least) logically located.

The body size and shape is a much closer match, and the control layout is also almost identical to the 450D, although the 1000D has the 400D’s 2.5-inch 230K monitor.

Most buttons are now to the right of the screen (unlike the 400D which had a set of buttons down the left side of the LCD).
