Would telephoto lenses for slr film cameras work with slr digital cameras?

Answer 1

If it will mount on the dslr, then it will work more or less.

Answer 2

Assuming your lenses match the coupling pins on the DSLR and focus on the same plane, yes. However, keep in mind you won't be getting the same image as you would on film as the digital sensor is generally smaller than what you would find in 35mm film cameras and there may be a slight color focus shift as the sensors have different focusing points for the RGB colors than does film.

Answer 3

Yes if the lens is the same brand as the camera if not you can always just get an adaptor which cost like 250$
