Nonsense. There is no such thing as "cropped focal length". What transform are you talking about? The lens ls projecting an image, in both cases, straight onto the sensor or film plane. Mayhap I'll borrow a Pentax film camera, stick an FA50 on it, fit an FA35mm on my *ist DS, and take a photo of a reference test subject. You will not be able to tell the difference, I guarantee it.
