When taking infrared pictures with infrared
film and either a "R2" or "02" filter, it is neces-
sary to adiust the focus because the point of
focus is not the same with infrared light as it
is with visible light. As shown above, memo-
rize the focusing point on the lens distance
scale when viewed through the viewfinder
and turn the focusing ring until the point you
memorized aligns with the infrared index.

focus mode only.
• For the exposure control requierd in this
special photography, see the information
supplied with the infrared film.

Infrared film can not be used for
MZ-S, MZ-60 and * ist cameras since
infrared ray is used for detecting device of
film transport. It will expose infrared film in
the camera.
