* Price: one shutter for many lenses versus one shutter in each lens. * Range of shutter speeds: leaf shutters on large lenses struggle to get to 1/1000 of a second. They can do 1/2000 on digital sensors by electronically beginning the exposure and mechanically ending it. The fastest focal plane shutters went to 1/12000 of a second (but most today are either 1/4000 or 1/8000).
