The Digital Rebel XTi is a compact, stylish and attractive DSLR that continues the design
concept of its predecessor, the Digital Rebel XT. The exterior surface is now coated with a
leathery paint finish to make fingernail scratches less noticeable. The Canon logo is a bit
bigger to make it stand out better in retail situations (2 mm wider and 0.4 mm higher).
To improve holding ease, a convenient new rubber slip guard for the thumb (back, top
right) and a new grip shape in the back have been incorporated. The grip is also thicker
by 1 mm. The texture of the mode dial has been changed. The Print/Share button is now
on the upper left on the back of the camera where the digital control buttons are concen-
trated. Clearly separating the digital control buttons and camera control buttons makes
the camera easier to operate. The new screen and the elimination of the bifurcated dis-
play give the back of the camera a cleaner and more integrated appearance.
The camera body construction of the
Digital Rebel XTi is very similar to that of
the Digital Rebel XT, a camera of proven
ruggedness and reliability. The stainless
steel chassis and mirror box made of
high-strength engineering plastic (polycar-
bonate with glass fiber) make the body as
strong as the XT's. As with the XT, the
camera's top, front, and rear covers are
made of special engineering plastic (ABS resin, polycarbonate resin, and polycarbonate
resin with special conductive fibers) for light weight, high strength, and electromagnetic
shielding. The XTi will come in two color versions, silver and black.
The basic internal components and configuration are the
same as those of the Digital Rebel XT. The following units
have been added or modified: Self Cleaning Sensor Unit
(added), Display-off sensor unit (added), LCD screen (size
increased from 1.8 in. to 2.5 in.), LCD panel (eliminated).
Note that in every parts category (except lead wires, which
remain unchanged at 12), the parts count on the Digital
Rebel XTi has increased relative to its predecessor. The
total is now 1508, compared to 1319 previously. This is a
good, if somewhat generalized, indication that the Digital
Rebel XTi is a more sophisticated, and more expensive to
produce, camera than the Digital Rebel XT, and that it
offers exceptional value in the sub-$1000 category.
