The single drive motor is mounted underneath and behind the rotating  
mirror shutter system.

Alas, this is not a "capping" shutter.

However, the shutter is actually a front-surface mirror, as one would  
obviously expect, and it is a "butterfly" shutter, as one might also  
expect.

However, to dynamically balance the shutter, and to reduce the  
camera's noise, there are arranged about the entire periphery of the  
shutter rotating support system, a very great number of very small  
machine screws, each of which is individually adjustable as to its  
radial location, thereby providing for the relatively large mass of  
the head of the machine screws, themselves, a greater or lesser  
position with respect to the axis of rotation of the shutter.

The adjustment procedure for this system is obviously quite complex.

But, it gets the job done.
