Re: more on focus distance

[Les Newcomer <lnphoto@xxxxxxxx>]

A couple of questions to make a few people smile and confuse others:

Is the FFFF in metric (for 35mm) or english (for Cirkut)?

Does ANSI know about this?

And the number 1 question (at least asked in Detroit/
tier 1 suppliers>>> Is this ISO 9000 compliant?
