Default Focal plane vs. leaf shutters in MF SLRs

Only at the synch speed or slower. At faster speeds only part of the
image is exposed at any one time as the shutter becomes a moving slit.
The higher the speed the narrower the slit.

This is why you have limited flash synch with a focal plane shutter vs a
leaf shutter.
