If you intend to take  infra-red photographs,

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.
