The Mamiya RB67 system, which is a big SLR, has a dark black flap that sits behind the mirror and swings up just after the mirror has lifted, and after the leaf shutter has closed immediately before exposure-time. Its well-sealed enough that a separate focal plane shutter is not necessary to prevent fogging. Its not quite as complicated as an actual shutter but it has the same effect.
