Compatible Teleconverter Lens for Canon 350D Rebel XT 8.0

I am new to the Digital SLR world. Recently purchased a Canon 350D Rebel XT
8.0 and need to know what teleconverters are compatible with this camera.
Also is the Vivitar 3X that was compatible with the EOS SLR Film Camera,
compatible with the Digital camera?

I've chosen to use only Canon brand lenses and converters. Canon make 2 that
will fit the Rebel XT (or in fact, any EF lens mount): The 1.4x and the 2.0x
(the first loses you 1 stop, the 2nd 2 stops).

The other side of the equasion though is that not all lenses can be used
with the converters eg the 70-200 F2.8L IS USM Can, but the 24-70 F2.8L USM
can't - there can also be other restrictions on which AF points can be used
for AF etc.

Do a spot of googling for the teleconverter compatibility chart.

Cheers,

Colin

Excuse me for asking, but your camera has a 1.6x crop factor, and you
intend to use a 3x teleconverter? Are the hubble telescope your ultimate
goal?

But get a decent telephoto lense, and forget about teleconverters. your
camera already act like one. And

Some lenses have much more resolution than a 1.6x XT can make use of.
The pixel-level detail of current digitals and RAW conversion is not
that great, too, and it doesn't hurt to oversample a little bit, but
there are limits. Even if the 3x TC were a good 3x, it would take an
extremely sharp lens to make it worth losing that much light. And you
do lose quite a bit of light using TCs; not just the stops you lose in
max aperture, but you also have to increase the shutter speed many
times, and stop down a little to get lens sharpness worth magnifying.
