A bit off-topic, but I *love* the Heliar design. I use a
50mm f/3.5 Heliar from time to time, and it's at this time
the only lens I've used that I would consider technically
"better" than the Zuiko 250mm f/2.0. It's exquisite. Here are
three (non-exquisite :-) photographs with the lens, all
scanned darkroom prints (5x7in):

As I said, first and only lens I've used which, in it's rendering,
actually improves
on the big white Zuiko - in a 12x16in print it's wholly remarkable. Of
course,
two lenses could not easily be further apart in size and weight (the
Heliar takes 27mm filters,
I believe the Zuiko takes something like 150mm filters :-)
So, the fact that the "look" of a 50mm f/3.5 lens that only focuses
down to 0.9m
can seriously excite a guy who has (or had) some very high-end other
50mm lenses
from several systems, means that the character and optical design of a
lens has a
large influence on the final products - not just the specifications,
or a single
axis of performance (e.g. resolution).

Dawid
