When using infrared film, you focus normally and them turnthe lens focus untill the point which was lined up with the normal focus index is lined up with the R. Don't use this with infrared ectachrome or (I've heard) with Konica infrared black and white. Both of these films are more sensitive to visible light than "true" infrared and use the normal focus index. Cheers! kw >Hello, > >in my lens 50mm f1:3.5 (elmar) there is a "R" in 5.6f .
