Roger Pellegrini Posted January 8, 2011 Share #1 Posted January 8, 2011 Advertisement (gone after registration) Can someone tell me what size filter I need for a 35mm and 50mm summicron for the MP. I see them online ranging in size from 35 - 39 mm. Thank you. Quote Link to post Share on other sites More sharing options...

stunsworth Posted January 8, 2011 Share #2 Posted January 8, 2011 The current versions both take 39mm Quote Link to post Share on other sites More sharing options...
250swb Posted January 8, 2011 Share #3 Posted January 8, 2011 Most (all?) of the current or latest lenses say it on the front, E39, E46 etc Steve Quote Link to post Share on other sites More sharing options...
samuelphoto Posted January 10, 2011 Share #4 Posted January 10, 2011 In the case of threaded filters, they all use 39mm filters. "E39" just means 39mm with the standard 0.75 thread pitch which is designated as "E" which is what Leica and all modern lens makers use. Older lenses did use filters with different pitches, Nikon RF's, for example. But for a modern lens, including Leica's, they will use the standard pitch. There are some exceptions. For example, the 35mm Summicron version 3 does not have filter threads. Instead, you need to get the correct matching shade which is made in two pieces. You unscrew the front from the back and drop in a threadless series 7 filter. Here is a very useful reference for Leica lenses. Quote Link to post Share on other sites More sharing options...
christer Posted January 10, 2011 Share #5 Posted January 10, 2011 .

At least for the 39s. And I thought E stood for Einschraub; screw in. Quote Link to post Share on other sites More sharing options...
lars_bergquist Posted January 11, 2011 Share #6 Posted January 11, 2011 Christer is right, of course. "E" stands for Einschraub – "screw-in", while most screw-thread lenses took "A" filters – for Aufschub, "push-on". And E39 filters do in fact use 0.5mm pitch. Larger filters use 0.75mm. The transition is not clean however; B+W supply 41mm filters in both 0.5 and 0.75mm pitch. The old man again Quote Link to post Share on other sites More sharing options...
wizard Posted January 11, 2011 Share #7 Posted January 11, 2011 Advertisement (gone after registration) Lars is correct. The "A", however, stands for "Aufsteck", as in "Aufsteckfilter". Regards, Andy Quote Link to post Share on other sites More sharing options...
christer Posted January 11, 2011 Share #8 Posted January 11, 2011 Wizard's statement is true. However, Aufschubfilter is really a great idea. My M7 lacks what my IIIG has: a Vorlaufwerk. (My computer translates this into "leading factory" but I rather doubt that is correct.) The common name in German is "Selbstauslöser". I often miss this device. Now think what an Aufschubfilter (correctly translated by my computer into "delay filter") could do if used on an M7. You attach it to the lens and after a certain delay, the length of which would depend on the filter factor, it makes an exposure. You could easily make pictures of yourself. If you so wished. ?

wizard Posted January 11, 2011 Share #10 Posted January 11, 2011 No Lars, your German is admirable. I would be happy if my Swedish was anything near as good (in fact, it is non-existant, but I am happy to pronounce Saab and Volvo correctly. I do like the Swedish way of pronouncing "Saab" ).
