Infrared Photography

Using

Infrared light rays-being of longer

wavelength - focus at a slightly dif-

ferent plane and require the follow-

ing adjustment:
1. Note the Red Index Mark against

which you read your distance scale.

The red infrared index mark is slightly
to its right.
2. After focusing in the usual manner,

read the distance scale and move it

to the right to line up with the infrared

index mark.

The 300mm and 500mm APO lenses

for Mamiya 645 cameras, being also
corrected for infrared light rays, do

not need an index mark for infrared.

For proper filter and exposure

information be sure to consult the
instructions enclosed with infra-
red film.

Socket accepts a standard 1/4” tripod
mounting screw. For use with tripods

having 3/8” mounting screws, first
unscrew the small black philips head
retaining screw in the center of the

tripod socket. Then remove the 1/4"

bushing with a thin coin. To re-install

the 1/4 bushing, reverse the proc-

ess.
