Guest user8952 Posted October 3, 2007 Share #2 Posted October 3, 2007 Hello, Could someone tell me the meaning and purpose of the '10' near to the M many thanks, Jeff it tells you the EXACT focal length (wich lens is it?) Link to post Share on other sites More sharing options...
delander † Posted October 3, 2007 Author Share #3 Posted October 3, 2007 It is the 90mm elmarit so how does 10 relate to that? On my 50mm summicron it reads 22? It is not present on the wide angle lenses Jeff Link to post Share on other sites More sharing options...
delander † Posted October 3, 2007 Author Share #4 Posted October 3, 2007 Perhaps it means that wide open, if you focus it to infinity everything down to 10 metres is in focus? Jeff Link to post Share on other sites More sharing options...
stunsworth Posted October 3, 2007 Share #5 Posted October 3, 2007 It means that the actual focal length is 91mm. See here for an explanation...

Michael-IIIf Posted October 4, 2007 Share #7 Posted October 4, 2007 Advertisement (gone after registration) Whao, that's a complicated esoteric way to write a number. Why not print 52.2, for example, somewhere on the lens? Link to post Share on other sites More sharing options...
lct Posted October 4, 2007 Share #8 Posted October 4, 2007 It means that the actual focal length is 91mm.See here for an explanation... Leica FAQ - Mysterious white numbers on lenses - meaning?... Did not remember this FAQ thank you Steve. According to Nemeth, those numbers "only appear only on the M 50, 90 and 135mm lenses" but my 35/2 IV has such a marking as well: 50 which means that it is exactly a 35mm lens if i understand well.
