Would my Canon EF-S lenses fit the Canon Rebel Ti 35mm film SLR?
The 50mm is an EF lens and will be fine, the 18-55 and 55-200 are EF-S and cannot be used on the film body. The rear element of the lens on those EF-S lenses extends further into the body than an EF lens. The mirror of a film body will actually strike the rear element of the lens. This is not a good thing. A 50mm f/1.8 or so used to be the standard “kit” lens on a 35mm camera. It is still a very good all-around lens on a film body. You can probably find comparatively inexpensive EF zooms on ebay too.
