Canon Lens Serial Number -question

[Lstop-photo]

Last night I got my new 24-70mm II from B&H – I noticed the serial number was xx00000050. Knowing this lens is in high demand, I was a bit puzzled to see such a low number.

I tested the lens and at first sight it seems to be in good condition. I need to test more this week-end though, especially the sharpness in corners and edges.

I guess my main concern is making sure I got a brand new lens, and not something that was returned by a previous buyer, Is there any way to check that out?

Thanks

Lenses are stocked in a warehouse, and not shipped in serial number order, so its entirely possible that low serial numbers may be appearing.  I'd think a low serial number would be very desirable, since they likely did extra QC on the first thousand or so lenses.

Your lens will have a Date Code which tells you where and when it was made. Have a look here: http://www.the-digital-picture.com/Canon-Lenses/Canon-Lens-Aging.aspx

Will it?  A date code is not stamped on some L lenses.

I just checked the lens, and I did not see any date stamp on this one (unless I am missing the obvious)

Hi Luc,
I received my 24-70II on the first weekend release here in Sydney (31 Aug).  My serial number is xxxxx00349, and there is no date code on this lens.  I've looked many times in case I'm missing something, but its not on all L lenses as Neuro said.  As MtSpokane also said, serial numbers are distributed out but are not necessarily sequentially sold - I wouldn't be too concerned.  I'm loving this lens and the quality of the images it helps produce.  I'm sure you will too.

As Neuro knows, some L lenses no longer use the alpha-numeric code that once used and are using numbers only. It is not understood to be a date code. I wouldn't worry about it unless you got a dud of which those are few and far between.
If you are a CPS member you might want to register the lens in your account and 'maybe' if it was pre-owned you might get a notice that it is/was registered by another user. Not sure if this is a possibility with their software.
You're going to love that lens!  Extremely sharp and smooth all in the right places.

Nor are they L lenses. Only a very few non-L lenses have them, generally really old designs like the 50mm f/2.5 Compact Macro.

Thank you all for your good replies. This is helpful.

One more question - I have read that this lens is sharp, center and from edge to edge.
Do you have the same observation? I'll be testing sharpness when I get off work today, espcially edges.

Thanks
Luc

Just checked my 17-40, 24-105, 70-200 F2.8 IS, 300 F4 IS, 300 F2.8 IS and 600 F4 IS - all have date codes, thought all L lenses had.

Nope. Your lenses are all older designs. My new 600/4 IS II does not have a date code.

I just sold my 28 f/2.8 and noticed it had a date code

My TS-E 24L II and TS-E 17 do not have date codes.

My TS-E 24L II and TS-E 17 do not have date codes.

Interesting. When did you buy your TS-E 24L II?  I bought mine in October, 2010 and it has a date code UY05.  Hard to see, though.
