The latest offering from Canon is the successor to the incredibly popular Digital Rebel XT entry-level dSLR. The Digital Rebel XTi is, in many ways, very similar to its predecessor, with a few alterations and improvements.

First, the XTi has packed in an additional 2 megapixels into its CMOS sensor, giving the camera a total resolution of 10-megapixels. The odd thing about this particular upgrade is that Canon opted not increase the size of the sensor, but simply cram in more pixels (with a pixel resolution of 3,904 x 2,598) within the same space. It is not clear yet what effect, if any, this will have on overall performance.
