Cannon changed the bayonet mounting pattern several years back, so compatibility is dependent on age of your lens.
If the mounting is compatible, you will notice a "cropping" effect on a Cannon APC format camera. The cropping factor is 1.6x, which means a 100-mm lens will capture images like a 160-mm lens on a 35-mm film camera.
I agree, depends on the model of the Canon lens.
the "FD" Canon lens require an adapter and will operate as manual only.
Need more info...
