[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Nathan, There have been four different filter systems used by Leitz/Leica over the years. First off, screw, usually described with an E prefix, at least in recent years, e.g. E39. Secondly, external clamp on, described with an A prefix, e.g.. A36, for fixing to the outside of a 36mm lens head. Thirdly, the short lived bayonet mounts for the Xenon, Summarit and a few other lenses. And lastly, the series filters held in place with a retaining ring or lens hood. Your filter requirements are presumably the first type, the number following the E number being the filter thread size, in your case, 39mm. Now Leitz were never one to let others muscle in to their market so they vigorously defended their right to present the weirdest range of filter sizes ever known to this planet. 39mm is one of the more common sizes but you try looking for a 41mm or even a 43mm filter. "48mm?" "Surely you mean 49mm Sir?" "54mm?" "Come come now, shall we try something else?" "67mm?" ...and so it goes on... Best of luck, frequently these sizes are available to order, especially through the Germanic suppliers, B&W, Schneider, Heliopan etc. Jem - -----Original Message----- From: Nathan Wajsman [SMTP:belgiangator@yahoo.com] Sent: 03 October 2000 12:49 To: LUG Subject: [Leica] A really idiotic filter question This may be the most silly question posed on the LUG this year, but I don't care...I am thinking of trying infrared film, and so have been looking at filters (deep red etc.). I have never used filters with any of my Leicas, and I do not understand the filter sizes. For example, my 50mm Summicron M has a filter size given as E39. All well and good, except that when I go to B&H's web site or Heliopan's ditto, I see no such size. All the sizes are given in terms of diameter, e.g. 55mm etc. So if I want to buy a filter for my Summicron, what size do I order????
