[rollei_list] Re: Fisheye Filters

........the world is still revolving then. ;-)
 
Thanks Ed.
 
Because the filter is part of the optical train, is the filter thickness
critical or is it just the number of glass/air interfaces? I can machine
a filter holder to insert the glass as opposed to destroying a rare Carl
Zeiss filter if thickness is not an issue.

If what you want is a user, then destroy the B11 and put your own orange
in it. Ed
