I hope you enjoyed this list of 2626 Leica lens serial numbers. Once of the best parts of owning Leicas is knowing that you can trace their history back decades because Leica has always been careful to keep track of their lens production.
In general I try to get later serial numbers simple because I prefer the modern glass... I have a 1990's Summilux-R 80mm that is simply great, don't think the tiny difference with a pre 1980 model would even show in print. OR would even be distinghuised.
There seems to be some confusion with respect to serial numbers of the early 35mm Summicrons. In Puts Chronicle, page 134, he lists serial numbers of the first Version (8-element) from 1.630.501 - 2.286.450.
My lens looks exactly like Lagers, no surprise since the serial number is only 4 numbers apart so there should be no doubt they are both 8-element (unless we are talking about a 6-element lens in an 8-element "body").
I am not a camera enthusiast but have come across a Summicron R 50mm which is made in Germany and the the serial number is from 1972. Does anyone know how much this should/would go for in £ ? Any comments appreciated. Thank you.
The company Ernst Leitz in Wetzlar, Germany started adding serial numbers to their lenses in 1931. The records are well documented,  and are a relative precise way to determine the age of a lens or a connected camera.
Actually, there should be a clear difference between these two versions on eBay, depending on whether they have a serial number of under or over 2 809 401 - because the newer MARK II lenses are better. But since many do not pay attention to the serial numbers, there is almost no price difference. Thus the purchase of the older variant due to a cheaper price is not recommended!
Offered is a Summitar 2,0/5cm from 1939 in good to very good condition. The elements are in good condition regarding the age of the lens and there is some oil residue on the aparture blades.What is special about this particular lens is that the serial number is followed by an asterisk. This means that the number has been assigned twice. So there is or have been a second lens with identical serial number.Cameras and lenses with duplicate serial numbers are extremely rare and therefore highly popular among collectors. 2b1af7f3a8
