Hi,
I use Contax filters on all my Carl Zeiss lenses. They're very good,
and very well made. Apparently they're made by Hoya, but they are very
different, and much better, than Hoya's own-brand products. I'd rate
them better than B+W, but that's a subjective rating. There is no
noticeable degradation of the optical quality of the CZ lenses.
Caveat, otherwise somebody will tell me that under a scanning electron
microscope any blind fool can really spot the difference and therefore
all filters are crap: no noticeable degradation means when I look at
slides on a light table with a 4X Schneider lupe or an 8X no-brand lupe,
or when I've seen the slides projected to about 1.5m on the long edge
through a Leitz enlarger & lens onto a high quality screen.
I've never used Pentax filters, so I can't tell you if their flare
resistance is as good. When I used Pentax lenses I was using B+W
filters. I can tell you that I get more problems with flare with the
CZ lenses than I ever got with Pentax SMC lenses, but I only get flare
when the sun is actually in the frame, so it's not a major problem.
