Distance Scale
The distance scale indicates the distance be·
tween the focused subject and the film plane.
The scale is necessary for checking the depth ·
of · field, for flash and infrared photographies.
• The correct position of the scale is in the
center of each value. For example , the correct
position of a two · digit value is the center of
the two figures .

Infrared Index .. R"
For infrared photography , correction of the
distance scale is necessary because the focal
point slightly deviates from ordinary photogra '
phy. Focus
first in the ordinary manner, then
adjust that distance scale to the infrared mark
" R ". For instance , if the distance scale reads
10m after focus ing, merely shift the 10 scale
to "R " posit ion.
