Changing the fibre optic viewing screen
In the 16 SR II instead of the conventional ground glass a
fibre optic viewing screen is used to reproduce the reflex
image. With the fibre optic viewing screen definition is better,
especially with stopped down lenses, as no ground glass
grains are visible. The fibre optic viewing screen has
markings for film and television formats and light meter
scale.
Should it be necessary to remove the fibre optic viewing
screen this operation is carried out with a special clamp
inserted in the lens bore. Care must be taken when
reinserting the fibre optic viewing screen that it is securely
seated, otherwise the image reproduced on the film and the
image seen in the viewfinder will not be identical.
