Question on compatability of lenses

[Rapala46]

Hey everyone. I have two sigma lenses that i am using right now on my Canon EOS T2, and as much as i love film photography, i think i might go to the dark side. I wouldn't sell my film camera, but instead, i was planning on buying just the body of the Canon XT Digital. This way, i could switch the lenses either way, depending on what im using. The only thing is, i dont know whether the lenses will work for the digital camera? can anyone help me?

PS: the lenses are:

Sigma AF-MF Zoom 70-300mm F4-5.6 DG Macro
And
Sigma AF-MF Zoom 28-70mm F2.8-4 High Speed Zoom

thanks to anyone who can help

Any lens that works on a film EOS camera will work on any of Canon's Digital SLRs, including the DRebel XT. So yes

But, since the sensor on the digital camera is smaller than the size of a 35mm negative, there is also going to be a crop factor, meaning that you won't be able to get quite as wide-angled shots as you can with your T2. I believe the XT has a 1.6x crop factor, meaning that the 28mm side of your second lens will act more like a 40mm lens. That also means you'll be able to zoom in a bit more, making the 300mm side of your first lens act like a 480mm lens.
