Here is what this reviewer had to say>> like this little camera! It's lightweight, it's intelligently designed, it works well and can make extraordinary images. Its LCD is worlds better than the disgusting greenish LCDs on the 30D and my 5D.
It's nice, but I prefer my Nikon D40, which costs less. I prefer cameras based on their usability. The XTi probably has more real resolution if you print everything at 20x30" (50 x 75 cm), but I rarely print bigger than 12 x 18" (30 x 40 cm). If you're the kind of guy who uses a tripod in broad daylight consider the XTi, and if you're someone like me who hand-holds and uses fill-flash, the D40 is much better.
It's very similar to the previous Rebel XT. This XTi version adds a bigger, more accurate LCD, a much needed Color Histogram and more pixels. Menus and general operation are very similar.
It comes as a body only, or as a kit with the excellent and inexpensive EF-S 18-55mm f/3.5-5.6 zoom lens.
The body sells for about $799, or $899 with the lens. The older Rebel XT drops to $699 for the body or $799 with the lens.
It's called the Rebel XTi in the USA and the EOS 400D elsewhere.
