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. --- Bob mailto:[EMAIL PROTECTED] Thursday, March 28, 2002, 3:19:41 PM, you wrote: > Can anyone speak to the optical quality of Contax filters?
