[Cameramakers] Resolution of Metrogon, with and without filter

[Robert Mueller]

Does anybody have an idea about how much the price is for using a Metrogon 
in one configuration versus the other, i.e., with or without the proper 
center filter?   I do not refer to loss of uniformity but degradation of 
the resolution or MTF values.

[Cameramakers] repair of filmholder, Kodak 5x7 filmpack?

[Uptown Gallery]

Hello:

1) When old filmholders develop cracks in, or loss of, the flexible hinge
that swings open to slip film in and out of the film holder, what is
appropriate to repair them with? I bought a roll of black photo tape from a
photo store, and it was the first think I thought of.

2) In  a box of 5 x 7 filmholders I got, was one different one that said
use Kodak film pack. I have heard of these for 4 x 5 film, but are they
still available for 5 x 7?
