Leitz used, and Leica still uses, absolutely standard filter sizes -- not always in the sizes other manufacturers used, but always consistent with normal filter sizing, save for the tapered 36.4mm filters used on the Summitar and the bayonet filter-mount used on the Xenon and Summarit. The "E" filters are screw-in sizes. "E39" is a 39mm by 0.50mm (?), for instance, consistent with B+W, Heliopan, Harrison & Harrison, or Tiffen sizing. The "A" filters are slip-on sizes: "A42" is a 42mm slip-on size, again consistent with B+W, Heliopan, Harrison & Harrison, or Tiffen sizings. The Series filters are consistent with the system set up by Kodak and once quite common -- Series 5, 6, 7, 8, 9, &c. I believe the Series 5.5 filters were actually Kodak Series 5, but I no longer own a lens to check this on. Marc msmall@roanoke.infi.net FAX: +540/343-7315 Cha robh bas fir gun ghras fir!
