Are Contax filters better than other brands?
Yes and No. Contax filters are high quality filters that do not detract from the optical performances of your the G camera lenses. They are not superior to other high quality filters such as Heliopan and B+W. Contax filters are superior to filters whose rings are made of aluminum, which use brittle films for their multicoatings, which are uncoated, or which use less than optical quality glass.
