Can Canon 35 mm EOS EF lenses working well in Canon EOS Digital Camera?

The EF mount is common to both Canon film and digital. Depending on the sensor format and associated crop factor, the lenses will have about 1.5x the equivalent focal length. So a 70-200mm zoom will behave like a 105-300mm zoom.

Hello,

Canon designed their digital cameras to accept the EOS lenses. For the most part, any of them will fit but the magnification will be slightly different than what you are used to. Because the sensor is a different size the lens has a magnification factor of about 1.5, making your lenses a little longer than the would be on a regular film camera.
