I just looked up Lieberkuhn reflector on The Googles...
Not sure if it would work, but I've got a big 49mm to 72mm filter-ring
adapter. All one has to do is remove the paint off the front of it and
you've got yourself a Lieberkuhn reflector.
Jan mentioned that possibility. The problem is that the threads are the wrong
sex.
Annnnd, speaking of concave vs. convex, the Lieberkuhn reflectors are concave, likely parabolic, not gender neutral
flat. This is why Jan talks about forming plastic with heat into a bowl shape.
[And, my 18/3.5 then wouldn't have a hood..]
So, I just MIGHT have everything. :)
Hmmmm .......
