Hi Bill, 300mm is 300mm regardless of the film format however the film format determines how much of the image circle is captured to film and therefore the angle of view across the diagonal of the frame. So a 300mm lens on a 67 provides ~17.5 � DAOV, on a 35mm camera the same lens will provide a ~8.25� DAOV.
