AF is currently typically implemented by having a small, secondary mirror behind the primary mirror, and a semi-transparent (not translucent, Sony!) area which lets some light through to hit the smaller mirror, and then the AF sensors on the floor of the mirrorbox. There may be other ways to do this. Anyway, thus some of the light is not used to make a bright image in the OVF, but to focus.
