Canon's 20D and Rebel XT, differences?

Are the sensor and processor the same in both cameras?

I remember when looking at the spec sheets for the 20 and the XT that they
had a small difference in pixel count. (small enough that they both end up
being a nominal 8 megapixel.

The slight difference in pixel count leads me to believe they dont use the
same sensor in both cameras.

I snipped this from dpreview.com

It's interesting that not only does the EOS 350D not use the same sensor as
is used in the EOS 20D but that Canon deliberately designed the pixel count
of the 350D to be less than its bigger brother. Despite this there's really
no visible difference between the performance of the two in this test. You
could easily perform a blind test and not know which crop is from which
camera. Remember that both also use DIGIC II hence identical tonal and color
response.

Different sensor sizes, giving you a 1.2 multiplication factor on the 20D
(so I've been told), -v- 1.6 on the 350D.

Not sure about processor speed, but the 20D can burst up to 5 FPS -v- 3 FPS
for the 350D.

The 20D also has a shutter rated at 100,000 shots -v- 50,000 for the 350D

for a comprehensive review from someone who's probably forgotten more than
I'll even know about photography.

FYI--I don't think that's true. That'd be on heck of a magnification
difference and folks would be flocking to the 20D to enjoy more
attainable wide angle performance. :-)

"The EOS 20D sensor (8.2MP, 22.5 x 15mm) is very slightly larger and
has slightly more pixels than the Digital Rebel XT sensor (8.0MP, 22.2
x 14.8mm)."

I don't think such a tiny difference would detectably changes the
magnification.

If that were true, that would put the 20D's sensor larger than that of the
1D mkII. The 20D and the 350D have virtually the same crop factor.

Give it up already. They have the same factor.

Looks like I have to eat humble pie on this one

My original reply came following a discussion with a friend who said that
lenses are always given in 35mm equivalent - because DSLRs vary in sensor
size, going on to quote how mine was 1.6, but his (a 20D was a 1.2) - but,
obviously he's got that bit wrong, or I've got the wrong end of the stick
somewhere along the line.

Still, that's the nice thing about admitting I'm wrong - I get to learn
something

If you get something correct once by accident, you never remember it
later on.

The 1D mkII has a crop of 1.3x, so your bud is suffering from delusions of
onedeeism...
