Focusing
According to your predominant photo-
graphic work you will have chosen be-
tween 3 permanently built-in viewfinder
screens.
The image is focused by rotation of the
distance setting ring (13) on the lens.
a) Screen with split-image wedge
This screen is particularly suitable for
quick focusing with wide-angle and stan-
dard lenses. Unless focusing is critical,
edges and lines of the object are mu-
tually displaced in the horizontal split
image.
A ring-shaped quadrangular micro-prism
screen surrounds the central split image.
This serves for the focusing of objects
lacking crisp outlines. Out-of-focus set-
ting is indicated by distinct flickering.
The surrounding field consists of tri-
angular micro-prisms, producing a
ground-glass screen effect. This sur-
rounding field is therefore used mainly for
focusing with longer-focal-length lenses
and in the close-up range.
