UKBROOKLYN Posted March 26, 2022 Share #1  Posted March 26, 2022 Advertisement (gone after registration) Hi folks.. I came across a Summicron 50 with a serial number 4076711 Problem is this does not seem to be in any of the Leica Databases or Summicron serial Number Ranges,,  Anyone come across this anomaly before ??

Advertisement Posted March 26, 2022 Posted March 26, 2022 Hi UKBROOKLYN, Take a look here Summicron Serial number not in database. I'm sure you'll find what you were looking for!
adan Posted March 26, 2022 Share #2 Â Posted March 26, 2022 Can you give links to the specific databases or ranges that are giving you trouble? Leica S/Ns (and ranges) are not especially reliable for information. Some are "crowd-sourced" - people submit their own lens numbers to build up an approximation of a database. But if some individual doesn't do that, the range may be incomplete. The S/Ns are not even fully reliable as to date of manufacture - I've had several early-production 90mm Summicron-Ms v.3, never produced before 1980, with serial numbers that date (according to the databases) to 1976 (!!)

cboy Posted March 27, 2022 Share #3 Â Posted March 27, 2022 Had a similar problem with one of my lenses in which I couldn't register it. Just need to email Leica for them to add your specific serial number with lens model to your account. Link to post Share on other sites More sharing options...
Capuccino-Muffin Posted March 27, 2022 Share #4  Posted March 27, 2022 Are you implying it’s a fake? Link to post Share on other sites More sharing options...

Exactly. Leica doesn’t have tine to mess with these things, collector’s nitpickings. There wat this MP the other day the “I love my MP” that was produced and sold fairly recently but which was in FACT a  Very early MP model from when the MP cameras were in fact M6 with a fresh MP top plate. Easily recognizable thanks to its M6 film door which is incompatible with the MP cameras. But what else can we expect from serial numbers that are engraved on easily replaceable parts such as a flash shoe or on a lens’ retaining ring... Edited March 27, 2022 by Capuccino-Muffin Link to post Share on other sites More sharing options...
UKBROOKLYN Posted March 27, 2022 Author Share #6 Â Posted March 27, 2022 Well thanks for the replies.. I guess unusual or untraceable serial numbers over a 100 year period should be expected.. Link to post Share on other sites More sharing options...
adan Posted March 27, 2022 Share #7 Â Posted March 27, 2022 Advertisement (gone after registration) Your number is fairly recent, and the 50 Summicron is a fast-selling lens in general (compared to, say, a 90mm Summicron in the 1970s). The odds are very high that it was produced in 2007 or 2008. If I wave my hands over my crystal ball, it tells me (sight unseen) that the odds are even higher that it has the 6-bit black-and-white coding engravings on the rear chrome mounting ring (Leica began installing those in 2006). And has the built-in sliding lens hood which appears on all 50mm Summicron lenses since the 1990s. And was assembled in the former Leica factory in Solms, Germany (the current Leitz-Park facility in Wetzlar only opened in 2014). Link to post Share on other sites More sharing options...
