    I have used metal covered self adhesive foam boards for cameras.

    Smaller quantities of the black version could be bought at amazon? Just avoid the bad stuff.

    I believe you are mistaken: The 450mm is f12.5 in a copal #1 and the 600 is f11.5 in a copal #3, but wrongly advertised as f12.5. Catlabs has one listed as such.
