It doesn\'t matter what the focusing screen shows - what matters is at which aperture you are actually focusing - which is at f/1.4, unless you press the DOF preview button. The focusing distance markings on the lens correspond to the focus point at the widest aperture.
Yes it does; it matters a lot. The screen does NOT show the correct DOF for a lens with maximum aperture of f/1.4 or so. So, you are actually focusing at the aperture that the focusing screen shows, which normally is f/2.8-5.6.
