​​​Our primary goal here in collecting these serial numbers is our ongoing effort to better establish the number of lenses produced by Ducati (the records are lost) in order for us collectors to better understand the rarity (and value) of our lenses. As a part of this we have also been able to identify more "Variations" than were previously known. Recently (2023) our friend Antonio Rossetto pointed out the 2 different versions of the Eltor, and we have identified the "Light" FAT version of the Teletor (2022) as well as the "Medium" Light version of the Lator (2023).
​In 2025 Antonio once again noticed that the different grip pattern on the early Lator Lens was not just cosmetic, but a "Knurled" thread for use with the early view finders. We extrapolated his information to find the Teletor was the same. Soon thereafter we also discovered that the Close Focusing distance between the two variations, dubbed V1 & V2 for both lens groups, were distinct, validating the new variations even further! Please refer to the table on the Ducati Lens History  page for all of the Variations known to date with our approximations of the numbers which may have been produced. This is an ongoing effort and your help in providing additional Serial Numbers or information would be greatly appreciated!!!

The Ducati Sogno Lens Serial Numbers have been a bit of a mystery, at least as far as the number produced, especially for the 4 rarest versions: The Luxtor, Eltor, Dugon and Argon. Please join us in our effort to identify as many as possible, especially these rarer versions. Just drop us a line with your lens serial numbers included, and any details as to the serial number location and color would be helpful, with weight included if possible. And please, don't be surprised if your lens is already listed here, we have searched eBay, Facebook, Worldwide Auctions, and any other sales or websites where photos of a lens could be found while compiling this list over the years.

(Last Updated October 2025 and will be again soon! Stay tuned!)

In preparation of the above pages, I must thank first Donato Consonni (Bencini Story) who began this list many years ago. I have been able to carry on expanding it with much research and the kind help of others, including especially: Manlio Malavolti (The Malavolti Collection), Gianni Medici (The Medici Collection), Yamane-san in Japan (who purchased the Ducati Family Collection), Watanabe-Ryuichi, Mario Casilli, Antonio Rossetto, Dario Mondonico  and other kind collectors who have shared with us. If you have a collection, or even one interesting lens, please also share your database or lens numbers with us for the benefit the Ducati collecting community, thank you!

For those who help, an Excel copy of this database is available. Just send us an email, we are happy to share the list in the hope others will carry on this effort. ​
