measured using a dial guage.
@The dial gauge was attached to the face
of the perimeter of the mirror, and measurements
taken. (refer tothe SHUMIKASE focus outline

to about a third in the C11 and to about
half with the C8.

Handling
@Having first loosened the guage screw,
it is focused by the "Focus" knob.
@Once focused, the screw is tightened.
@The focus shifts for a time.
@The time to focus is measured over a few
times.
@The trick is to find the place where the
Focus knob doesn't move and it stays in focus.
