I expect that the high end B+W (they do make some low end stuff as well), Heliopan or Pentax SMC are of similar optical quality. Brass was better than aluminium because older lenses often had aluminium bodies, and the like metal filters would electrostatically weld themselves onto the lens. In this new era of plastic garbage lens barrels, I doubt if it makes any difference. William Robb This message is from the Pentax-Discuss Mail List.
