The EOS Digital Rebel XT camera
takes its place alongside the original 6.3-megapixel
EOS Digital Rebel camera that first placed an
affordable, high-resolution digital SLR into the
hands of Canon consumers. The EOS Digital Rebel
XT model is offered in two kit configurations:
with Canon's high-quality EF-S 18-55mm f3.5-f5.6
zoom lens (in matte black and in brushed silver)
and as a body only (in matte black and in brushed
silver).
The Canon Digital Rebel XT's
image sensor
The Rebel XT's image sensor has the same 3:2 ratio
as film cameras, creating an effective angle of
view that is 1.6 times the normal EF lens's focal
length.
While many of the feature advancements and innovations
on the new EOS Digital Rebel XT digital camera
are inherited from Canon's EOS 20D "prosumer"
SLR, the two cameras' most striking technological
similarities are their use of Canon's newly developed
large-single-plate, high-sensitivity, high-resolution
color CMOS imaging sensor technology. While the
size of the APS-C CMOS sensor on the EOS Digital
Rebel XT SLR is fractionally smaller than the
APS-C CMOS sensor on the EOS 20D camera (22.2
x 14.8 millimeters versus 22.5 x 15.0 millimeters,
respectively) accounting in part for the cameras'
8.0- vs. 8.2-megapixel resolution rating, individual
pixel dimensions are identical, and they both
provide the same effective angle of view, equivalent
to 1.6x the normal EF lens focal length.
There are, of course, some
very real differences between the EOS Digital
Rebel XT digital camera and the more advanced
EOS 20D. While the 20D SLR includes performance
features such as faster continuous shooting speed
(5 frames per second [fps] vs. 3 fps) with larger
burst capability (23 frames vs. 14 frames) and
custom function settings (18 vs. 9) that more
than justify its heftier price tag, this new Rebel
XT model was created for those dedicated SLR users
who are migrating to digital for the first time
and don't wish to give up the flexibility an SLR
system offers.
