The three-digit code on the surface of the lens is to indicate the year the lens was first released.(Since it is different from the year of manufacture, the release year and edition number may not match depending on the mount.)
Sigma Lens Serial Number Lookup
We will suspend all shipments of the applicable product until the cause of this matter has been identified. Once we know the cause, we will be in touch with the small number of affected customers to advise on whether we will repair their lens or replace it, and how this process will work.
I received my Sigma 14 yesterday and was amused to see the serial number appears to be "017". But perhaps that number (located underside near the mount) actually isn't the serial number after all (the leading zero seems odd). Do low serial number lenses usually get a higher or lower resale value? Not planning on selling it just curious. I'll be shooting with it this week underwater although I haven't tested the port situation for it yet so that may go nowhere. Will post photos when I get them.
On a lens, aperture is denoted with an F-stop (really just another name for aperture). This may also be denoted by an 1:2.8. If you look at a lens, the number that follows the F tells you the widest point that the aperture can go. Although it may seem counterintuitive, the smaller the number following the F, the wider the aperture! (This is actually a mathematical formula where F = focal length, the optional Slash mark / indicates division, and the number given denotes the radius of the aperture opening.)
There is an interesting list of known Canon Dream Lenses in existence here. You can compare serial numbers and see how early the lens was produced, or read about the history of some of the lenses and their current owner.
Sigmas made in Japan from 1970 through 1979 used a paper label to identify the model and serial number of the instrument. The model and serial numbers were usually stamped on in ink, but some are known to have been hand-penned. This is especially true of unusual, special (sample/prototype models) and/or low production number models (e.g.: DT-30.)
Under the best of circumstances, Sigma serial numbers can only provide an indicator of the year when a particular model was built. This may be due to them being built in several Japanese factories at the same time with no coordination or tracking in the numbering system.[citation needed]However, while some models lasted the entire run from 1970 through 1983, others did not and were only offered for a limited number of years. Other physical indicators or attributes, such as finish, trim, tuners, etc., can help determine the approximate construction date of a particular example, but almost never exactly.[3]
Sigma-Martin USA guitars built in 1981 and 1982 only had specifically assigned serial numbers ranging from 900,001 to 902,908 (2,908 in total.) These serial numbers are documented by C.F. Martin & Co. and to this day remain the only Sigma-related serial numbers that are publicly available. These "N" instruments, of which only two models were ever produced, the DR-28N and DR-35N, were partially assembled in Japan and imported to Nazareth ("N") and the Martin guitar factory as kits. Martin completed and finished them alongside the regular Martin production line. Bridges and tuners may have been installed, as well final sanding and finishing before strings were installed and a final set-up was done. Because more than 30% of the work was completed within the borders of the United States, Martin was legally allowed to designate them as Made in U.S.A.[5]
Serial numbers for Sigma guitars built in South Korea, Taiwan and Indonesia are perhaps even more meaningless, though again some seem to indicate the year of manufacture (e.g. loop81XXXXXX.) Since we know these instruments were manufactured from 1984 through 2007 in these three countries, it is safe to assume that a serial number beginning with 81XXXXXX (which I have personally seen) were not produced in 1981 and that these serial number 'indicators' are not to be trusted.
In 1978-'79 the paper labels were discontinued and the inner back brace was "branded." Later Korean production show a resurgence in the paper label system for model and serial number, sometimes along with the brand. These had an even fancier border.[citation needed] High end models such as the D-10 Anniversary model have the "Second Generation" logo inlaid in the headstock using mother of pearl, as do many of the later Korean produced instruments.
Some guitars made later in Taiwan and Indonesia have a different headstock shape and decal: The shape is more squared off at the top corners, while the decal states, "Sigma Guitars" on top with a miniature version of the "C.F. Martin & Co." logo underneath. Some of these guitars also had the "Est 1970" instead of the C.F. Martin & Co.," using a slightly different block font that is both fatter & wider than the original 2nd series instruments. The paper labels for model/serial number identification had also changed again, this time with a fancy border and the word "Sigma" or "Sigma Guitars" printed in gold ink.
In the years of 1981 and 1982, Martin imported partially assembled Sigma guitars from Japan and the assembly was completed in Nazareth, Pennsylvania. There were only two models, labeled "Sigma Martin USA DR-28N" and "DR-35N", 'N' for "Nazareth". A Martin factory sales brochure shows the DR-28N retailed at $600.00 and the DR-35N retailed at $650.00. The DR-35N had a three-piece laminate rosewood back and sides and a solid spruce top. The DR-28N had a two-piece back. The DR-35N had additional detail on the fretboard. The original factory brochure also states components were processed and finished on the same production line as regular Martins. The peghead logo reads "Sigma Martin USA" and inside the sound box is on the neck block "made in USA" with Martin address etc. Some consider the DR-35N to be a prototype of the inexpensive laminate Martin Shenandoah line of guitars,[18] later to become their current HPL (High Pressure Laminate) line of laminated bodied guitars. Since these models had serial numbers ranging from 900,001 to 902,908,[5] it appears only 2907 of these "Sigma Martin USA" guitars were ever produced in total, though there may have been others that did not make final inspection and hence were not serialed and are the only Sigma-related serial numbers publicly available from Martin at this time.
To check the serial number of a Sigma lens, customers can either find it printed on the side of the box the lens was sold in or etched above the Sigma logo on the side of the lens as shown in the graphic below:
Hey guys, help an old blind man out. I'm looking for the serial number on my lens and can only find one number that seems possible, but I can't believe it's correct. It's in white letters directly 180 degrees from the white line that shows the top when you mount it, and it's just 3 digits, '015'. Hey FenderBender, Welcome to the forum. Dating Sigma guitars is not an exact science. AFAIK the serial numbers do not correspond to dates. Others on the forum are way smarter than I, but I think the best that can be done is to narrow it down to a decade or two based on the country of origin and couple of other physical traits of the guitar. Stolen cameras and lenses for Canon, Nikon, Leica, Tamron, Sigma. Search stolen gear by serial number. Type a serial number of a stolen match. Example: 75165.
The lens was purchased in March 2012, so the code '83' for October 2011 is reasonable. The digit '5' for a revision code is also reasonable for a lens that's been around for a few years (1993), but we are left with a 5 digit serial number.
As shooters travelling the world, I'm sure all of us dread the day when our equipment gets stolen off airplanes etc. Here at Wetpixel, we've decided to help people list their stolen/loss goods like housings, cameras and other things that have serial numbers. This way should any of the missing equipment show up in the 2nd hand market, potential buyers will have a reference list to check if they are buying stolen equipment. This can possibly aid in arresting the thieves and perhaps even gear recovery.
The first EPIC 5K Digital Cinema camera shipped and delivered has been stolen in France...the serial number is 00006....Please contact Mark Peterson or the folks at RED Digital Cinema if anyone knows anything about this...There is a $100,000 reward leading to the recovery and conviction of the people responsible for this....
Stolen Nikon D500 and 2 Sigma lensesNikon D500, its a pitty, but i didnt got the paperwork from Richmond Camera UK, so i dont have the serial number...Sigma 105mm F2,8 EX DG Macro OS Serl Nr 14752926Sigma 18 - 35mm F 1,8 DC Ser Nr 51083674
Be very thorough when you look for serial numbers. As you can see in the image above where the number is on the lens barrel, they can be quite faint and hard to find. There might also be some other manufacturing numbers, so your best bet is to just record everything if you have any doubts.
And one last tip. When you buy new gear and decide to throw away the box, grab a pair of scissors, cut out the part with the serial number and other information, and stick it in a file folder somewhere.
A Canon warranty appropriate for your region should be provided. For EOS R, the box should contain a Product Serial Number Card with the product serial number printed on it.The serial number on the product, box and card should match.
The product with the serial number that you provided was not originally intended by Canon for sale in the European Economic Area; we therefore advise you to contact the seller from whom you originally purchased this product. Please check the "Where to Buy" section on our website to find a local retailer to source a Canon product intended for sale in your region.
