So while waiting for my dad to finish a long treatment at the cancer
center this morning I was casting about for large format lenses to put
on the Omega/Toyo 45D that is on its way from KEH. I tripped across a
Fujinon SW 90mm f/8 with issues for $179. Specificially, it was
described as having "Scheineritis" which was a new term to me.
Googling it, it appears that it is a separation of the lens from the
black coating/metal around the perimeter of the lens. It looks bad,
but according to what I found, it is harmless to the image quality as
long as it is out of the optical path. So I decided to take a chance
and made an offer on it, which was accepted.
This evening, I get an email from the seller saying "Looks like you
are very lucky, because when I pack the lens all white stuff in front
element gone and lens looks now almost perfect. I have now idea its a
magic or something else. Let me know if you have white circles again.
Alex."
This is rather odd, isn't it?
The original photo of the problem is the 2nd one in the listing:

Anyone have any ideas?
The listing has ended & it won't let me look at the photos.
