INFRARED INDEX MARK
If you intend to take Infrared photographs using
infrared film and R2 or 02 filters, it is necessary
to compensate for the difference between visible
light focus and infrared focus. As shown on the
right, note the subject-to-camera distance on the
lens distance scale as you focus through the
viewfinder and turn the focusing ring until that
distance setting aligns with the red infrared
index mark. The figure shows an example In
which the subject-to-camera distance is set at
infinity ( ).
For details on exposure control, refer to the
instructions accompanying the film.
