wizard Posted January 25, 2010 Share #81 Posted January 25, 2010 Advertisement (gone after registration) And yes what you see above is a 35/2 IV. Having bought it 20+ years ago i begin to know it a bit. I would have thought so, but the focusing tab is quite different on your lens than on my own version IV, which made me think yours isn't a version IV. Your lens must be an early version IV then (serial number below 3 000 000?). Andy, yes, I've got a first generation 135/2.8 R lens, which carries the numbers. And I may now confirm that my second generation Elmarit 180 carries the numbers, too. It has "80" engraved, making it a 178mm lens. So it seems that most R lenses above 35mm had these numbers up to a certain point in time (my guess is roughly up to serial numbers 3 300 000 - 3 400 000).

lct Posted January 25, 2010 Share #82 Posted January 25, 2010 ...Your lens must be an early version IV then (serial number below 3 000 000?)... Yes as the 50/2 from same period, the 35/2 IV may have 2 different tabs a concave one and a convex one. Mine has a convex tab from 1979 (code # 11310, serial # 2975***).

My R-50/2, R-90/2 and R-180/3.4 from 1978 & 1980 (serial # < 3 000 000) don't have those numbers either. Link to post Share on other sites More sharing options...
wizard Posted January 25, 2010 Share #84 Posted January 25, 2010 My R-50/2, R-90/2 and R-180/3.4 from 1978 & 1980 (serial # < 3 000 000) don't have those numbers either. You have to look closer . On the other hand, your Summicron version IV has them, that offsets your other lenses not having them. Still funny though, as I own R lenses > 35mm with serial numbers between 2 600 000 and 3 400 000 that all bear those numbers. Andy Link to post Share on other sites More sharing options...
peter_n Posted January 25, 2010 Share #85 Posted January 25, 2010 Zeiss ZM lenses do not use them, either. It's a Leica thing.I know. It was a little joke, there was a wink at the end of the post... Link to post Share on other sites More sharing options...
clw Posted January 30, 2010 Share #86 Posted January 30, 2010 Whoops, I'm sorry. I meant to post "Granite" and "Volcanic Silica". I see now that was a myth that I had been told by someone working in a camera store locally. Thanks! Link to post Share on other sites More sharing options...

Leicaquarters Posted February 8, 2010 Share #88 Posted February 8, 2010 Years ago I heard the following story. As Leitz was obliged to produce lenses during WW2 they sabotaged the production. First they cooled down the glass very slowly and then put the glass in a sort of rubber bed to avoid any movement of the glass. In the end they started to polish the glass and indeed the quality was uncompared. I still wonder if this story is true or kept alive to build the myth of Leica lenses Link to post Share on other sites More sharing options...
