Thanks for the offer I want to keep the work and costs contained, so I'm
sticking to Zuiko's.

There are lots of possible combinations of magnification, which again would
make the job get out of hand.  I settled on 1:40 since the range of Zuikos
from the 18mm to the 350mm were capable of it and I could do it indoors in
either a living room or a  multi-purpose room at a local public facility.  One
has to keep as many confounding factors as constant as possible to be able to
compare the performance of that great a range of lenses.  By viewing the same
image on a series of slides, one can visually see that differences without
having to mentally adjust for variations in test procedure.

>  Great job on the test.

Thanks.  The next round should be back this coming week.  And look for a
smaller Round 3, too, thanks to the trusty lenders on the list.
