Eric,
You are overlooking the issue here.  It is important whether there is
"crazing" on the lenses or not because a potential Custom buyer won't know
to look for this defect if he/she isn't aware of it . Whether the Custom
lenses are better than Ilex Paragons or Ektars is another discussion
altogether.

Now, as to the technical aspects of this "crazing," I don't know whether it
is fungus, fungi or mice.  What I do know is that it does impact
performance because I have seen it and so have some of my customers.
That's why I suggested that an article on this very topic might be
appropriate for INSIDE 3D Magazine.  How about you doing one?  I could
provie the crazed lenses and you could do the inspections and write about
the results?  Yes?

Meanwhile, any person considering purchasing a Custom, please examine the
lenses carefully.

And by the way, even collector would be nuts to buy a Custom with the lens
defect even it if the most beautiful Custom in the world cosmetically.
