Yes, with a FD to EOS adapter.
Yes you can use it but you need a FD to EOS adapter.
Yes, via a lens adapter available from aftermarket producers. All Canon FD lens to Canon EOS lens mount adapters will contain an optical element to provide correct focus at infinity. This is because the Canon FD lens flange focus distance (distance from the focus plane to lens mount) is shorter then the Canon EOS lens.
All bayonet mount canon camera's in the past 30 years will accept an FD lens'. The AE 1 and later ones will accept the lens' but will only work on automatic if the lens has the A setting on the lens.The FD will not work on an auto focus.
No, not without an adapter. There are adapters avalable that lets you mount FD-lenses on newer Canon EOS cameras with EF-mount
The Canon AE-1 camera uses FD mount lenses. Canon made FD mount cameras and lenses from 1971 through 1987. FD lenses are manually focused. FD lenses are no longer being manufactured, but are available for incredibly low prices on the used market. Ebay is one good source.
It is an obsolete lens mounting standard developed by Canon that has not been in production since about 1990. It was superceded by the EF (Electro Focus) mount for EOS lenses, which were the forerunners of electronic focus. Apparently, Canon has never divulged what, if anything, that FD stands for.
The AE-1 lenses have Canon's FD breech-lock lens mount. They are not compatible with Canon's later EF lens mount. It may be possible to find an adapter, but performance would be lost, and the lens will not have the features of an EF lens. Best to save your money and get a dedicated lens, either Canon or Sigma.
No. You can't use it on Canon's autofocus film cameras either.
The short answer is: "No" The long answer is: The T70 uses Canon FD mount lenses. FD lenses can only be focused manually. All of the exposure communication connections between the camera and lens are mechanical. An EF lens will not fit onto an FD body. In 1987, Canon introduced EOS cameras that use EF (electro-focus) lenses. All of the exposure and focusing communication connections between the camera and lens are electrical. An FD lens will not fit directly on to any EOS camera. The Rebel XSi camera is a Canon EOS digital camera that can use EF lenses or the smaller EF-S lenses made for APS-C DSLR's. Adaptors are available on a popular internet auction site that will connect an FD lens to an EOS body. The price in 2008 is just under $40, including shipping. Lens functions are manually adjustable only, and are not very convenient when used in this way.
I don't think they will fit any. The lens mount was changed right after the Canon T70. Someone told me they will fit a Nikon so I'm trying to find that out. (They don't fit Nikon cameras.) Canon T70 lenses only fit Canon SLR's (single lens reflex) made between 1964 to 1987. The T70 uses Canon FD mount lenses. FD lenses can only be focused manually. All of the exposure communication connections between the camera and lens are mechanical. An EF lens will not fit onto an FD body. In 1987, Canon introduced EOS cameras that use EF (electro-focus) lenses. All of the exposure and focusing communication connections between the camera and lens are electrical. An FD lens will not fit directly on to any EOS camera. The Rebel XSi camera is a Canon EOS digital camera that can use EF lenses or the smaller EF-S lenses made for APS-C DSLR's.

In short, yes. More specifically, as long your zoom lens is an "EF" mount lens, it will work with all Canon Digital-SLR models from the EOS line. You can determine if a lens is an EF mount from the full name of the lens. The full name of the lens is usually written on the outside of the len itself.
