Shutter Question

[skyonfire]

Ok this may be a stupid question.. But what is the difference between a focal plane shutter and a leaf shutter??

A focal plane shutter is at the film plane, and usually consists of curtains that run horizontally across the plane. A leaf shutter is in the lens, and acts similar to the aperture, and opens and closes in a circle. Because of this, a leaf shutter can sync at all shutter speeds, but because of the design, normally the top shutter is 1/500, or 1/1000.
