A pro I know has a lot of Cokin filters that he uses for MF shooting

Despite the Cokins being plastic (acrylic?) his after 10 years were hardly
scratched. He's a very "deliberate" shooter.

The problem with Cokin filters is/was not that they are "plastic", and thus
scratch more easily than glass filters.
Lee or Cromatek filters, for instance, are also made of "plastic".

The problem is/was with their quality: too many Cokins were/are uneven in
optical density (not the colour - see later - but the material itself
showing "schlieren"), warped and twisted, and not the right colour, or not
evenly coloured.

Be that as it may, the fellow in question uses only Cokin and he's a
regular photog contributor to a few NA nature/outdoor rec. mags.
Whatever harm they do to the photos would not seem to be apparent enough
to matter.
