RE: HIE in Hasselblad

["Charles Jay Pilzer" <cjp@xxxxxxxxxx>]

Pete,

Why do you need two lines for the different filters?  Are you trying to
focus at the different cut off wavelengths of the filters.  How important is
this degree of correction?

It turns out that my CFI lenses do have a dashed white line where the IR
focus index should be.  All other lenses that I have seen have only one IR
index.  For what length is that one IR index usual set?

Thanks, cj
