I remember that... probably should be 600lp/mm, because 600lp/inch is only
about 40lp/mm, which isn't all that impressive. I remember seeing somewhere
that the typical Pen F lens was capable of pretty impressive resolution,
something like 80lp/mm or more... the supposed need to provide more
resolution due to the smaller film format resulted in some pretty
high-quality designs.
