On our Leica TCS/NT there is a table in the help file which details the optimum
pinhole size for each lens. If you use a pinhole setting of 1 then the size can
be found from the table. Unfortunately if you use a setting other than 1 I have
no idea how this relates to the actual size. It is logical to assume that a
setting of say 0.9 means 0.9 of the value at a setting of 1 but you would have
to check with Leica in case it is a non linear scale.
Hope that helps
