Interchangeable lenses

[Dottie]

Any cameras that can use AE1 35 mm lenses, eg FD 75-200mm , 1:4.5

I am asumming you want to know if a current DSLR made today uses an old film FD kens?

The answer is, no!    They are simply not worth the effort.

Canon no longer makes camera bodies that use FD lenses.  EOS cameras all use EOS lenses.

FD lenses are all manual focus and the connection between camera body and lens to control aperture is mechanical.  Since the lenses were manual focus, and it's a 35mm camera, they use a nice big bright viewfinder with an easy-to-use focusing aid (split-prism) to make manually focus very easy to do.

EOS lenses, in contrast, tend to be all auto-focusing (there are a few exceptions... the TS-E and MP-E lenses are manual focus.)  The interface between the camera body is now fully electronic.  Since the lenses are auto-focusing, they no longer put focusing aids in the viewfinder (they indicate the loction of the auto-focus points and these blink when the camera locks focus on them.)   Most DSLRs use a smaller sensor (it's not as large as a 35mm frame) and that means the reflex mirror and viewfinder are all a bit smaller as well.  It's not nearly as easy to manually focus as it was with, say, your AE-1.  That's no problem when the computer is handling the auto-focus for you.

If you "convert" an FD lens, you'll have to deal with the lack of any lens control and lack of auto-focus and focusing aids.

Where there are some companies that make adapters, these degrade the optical quality.

So while it is *possible" to adapt an FD lens... the outcome typically results in quality that makes you wish you hadn't bothered.

Hence most people suggest you invest your money toward new lenses.

The OP didn't really ask specifically about using Canon FD lenses on Canon EOS DSLR cameras. 

Canon DSLR's are difficult to use with old Canon film era FD lenses, but almost any other brand of camera can use these lenses quite easily and with quite good results.

All that is needed is a simple adapter that goes between the lens and the camera.   A good example is the many 4/3 cameras or any of the mirrorless cameras with interchangeable lenses.
