Special Film Usage
Shooting with Infrared Film
When using black and white infrared film, make
a slight adjustment in focus with the red infrared
index. For example, focus the subject first, then,
if the lens is focused at 5 m on the distance
scale, turn the manual focusing ring to align the
5 m mark with the red dot and release the shut-
ter. For zoom lenses, use the small red lines to
align with the number as shown.
-Use a deep red filter as specified by the
manufacturer.
-The infrared index mark position has been
computed for infrared film usage with peak
sensitivity at 800 nm.
-Follow the manufacturer's instructions when
using color infrared film.
