Changing the viewing screen
The viewing screen can easily be removed by the user. First remove the port
cap. Remove the battery (s) and clear the mirror shutter so that it is posi-
tioned safely inside the body by rotating it close to its center shaft with your
finger. Look into the port and look at the screen directly above the aperture
gate (G). Get a piece of Post-it, that will take-out the viewing screen without
dirtying it. Put the Post-it on your forefinger, the sticky part of it facing up.
Smoothly put a finger on the viewing screen, and remove it.
To reinstall the screen, look into the port and locate the right and left lip of
the viewing screen holder. Gently push the screen straight into the holder,
aligning the two white marks of both holder and screen. Proceed as before,
with a piece of Post-it on your finger.
Adjusting the viewing screen
The image focus on the viewing screen (ground-glass) should match the lens
barrel focus mark and the focus on the film. Before adjusting the viewing
screen, be certain that the flange focal distance of the camera is set accord-
ing to the manufacturer specifications.
To proceed, you must unscrew and remove the cap (H) located on the Oper-
ator upper side of the camera body. The open hole gives access to the
screen holder that you can up and down move by turning its Allen screw
(2mm Allen key).
Set a focusing chart at a known distance. Adjust the focus mark of the lens
to the same distance. Get a sharp image on the ground-glass by moving the
holder up or down with the Allen key. Double check the focus of the viewing
screen using the focus ring of the lens. If the image is still not sharp, perform
this operation again.
