Canon Lenses Ef Ef-S

"My Canon EF-S, is the Rebel Ti 35mm SLR Canon?
I have a Canon EOS 450D with three lenses (55mm-start a 18 and a 55-250mm 50mm f / 1.8 II) and I think to buy a film camera very cheap and I found the Canon EOS Rebel Ti 35mm (body) for £ 40 on Amazon. Now I'm doing my GCSEs at school so I have little money to spend on photographic equipment, and I was wondering, my glasses I have for my SLR Film SLR digital form? This is probably a really stupid question, but thanks anyway:)
The 50mm is an EF and it will, however, are 18-55 and 55-200 EF-S and can be used in the body of cinema. The back of the objective element in the EF-S, extends into the body of an EF. The mirror of a body of the film to actually find the rear element of the lens. It not a good thing. A 50mm f/1.8 or so used to be the standard kit in a 35mm camera. It remains a very good all around lens on a body film. You can probably find an EF eBay also relatively cheap.
