Larger format cameras generally use a "leaf shutter" built in to the lens instead. These are more complicated. They have multiple blades around the aperture that open and close, much like the f-stop control. But a leaf shutter closes the aperture entirely, opening up for whatever the exposure time is. This avoids motion distortion, and also allows faster sync with flash. But you need a shutter built in to each lens, making lenses bigger and more expensive. And they can wear out.
