remember to use the infra-red index marked with
an orange line or a small "R" on the depth-of-field
guide.
First focus your lens on your subject. Determine
the lens-to-subject distance from the distance
scale. Then match your lens-to-subject distance to
the infra-red index by turning the distance scale
accordingly. For instance, if your subject is in focus
at infinity, turn the distance ring and move the
infinity ( ) mark to the index. The index marking
on the Takumar lenses is based on the lens setting
at infinity.
