OK, I learned something today! Thanks!! I never knew that the larger format cameras had larger focal length standard lenses, I never thought about it and just assumed the lens was just physically larger on a larger format camera.
So field of view is the correct measurement of a lens vs focal length? I equated field of view with the angle in which the lens sees, such as 18mm equals wide angle and a 600 mm equals very narrow angle. Even at both of these extremes the image can be cropped for a narrower field of view ... then I guess to get to a standard size the image would be magnified.
Also, longer focal lengths give you a smaller DOF (more blurred background and foreground). So with a larger piece of film, or sensor, you don't need as wide of aperture to nicely isolate the subject from the background, because your focal lengths are longer which makes your dof smaller.
