I have the Omega C700 and I am waiting for the 75mm lens (due today). I bought a set of Ilford contrast filters (3.5x3.5) not quite the right size. Do I trim them down so they fit into the filter drawer (worried that they will not stay flat)?
I trimmed mine to fit, they were supposed to be 3x3, but were about 1/8" too wide. You can use scissors, mat knife or anything really sharp. Being that they are the negative, flatness does not factor in, nor do fingerprints. We have three C-700's in our darkroom, two for 35mm, and one dedicated to 6x6.

Are you sure fingerprints don't count? Flatness, to a point, shouldn't matter, bur when I think back many many years to when I used a communal darkroom, 'fingerprint' could mean anything from a barely discernable smudge to a gob of peanut butter (or Marmite if you are a UK type) that would make everything into a foggy morning. Cleanliness is next to Cartier Bresson!
