Everyone having a different keenness of sight, it
is necessary for the camera user to set exactly and then
lock the dioptry adjustment which corresponds to his
vision.  This can be done with or without lens mounted
on the camera.
Adjustment with a lens:
1. Place L5 to the right or to the left according to the eye
you normally use.
2. Make sure that the reflex mirror is in the front of the
aperture, if not, turn knurled button 31 which controls the
motor axle (see page 24, par. 5)
3. Turn control ring L2 to open the eyepiece shutter.
4. Focus the lens on infinity.
5. Diaphragm wide open or slightly closed to darken the
ground glass.
6. Loosen knob L3 and turn slowly in one way and in the
other the dioptry control ring until the frame and cross
engraved on the ground glass are perfectly sharp.
7. Take note of the number of dioptries in + or - that
corresponds to your sight.  Lock the dioptry control ring in
that position by tightening the button L3.
This setting should always be kept as it will permit
you to focus sharply at any distance.
