zone focus on film with zeiss zm lenses

[splash_fr]

Hi all,
short question concerning dof scale on zm lensen.
Do you always use the scale on the lens for zone focusing or do you use different circles of confusion and calculate dof with different films under the presumption that e.g. panf50 is sharper than trix@1600?

do you use the scales "as is" or do you give half a click security margin?

rgds,
gerd.

I use the scale as-is, and sometimes I do the one-stop-extra-safety thing. I make no allowance fo different film types, because the scales are intended for normal viewing, not pixel-peeping (or rather, grain-peeping)...
