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.
•
Turn the focusing ring in the MANUAL
focus mode only.
•
For the exposure control requierd in this
special photography, see the information
supplied with the infrared film.
•
Caution :
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.
