I just got a contax III with a sonar on it and I’m quite puzzled..

According to the first post of this topic : the lens has been made between 1942 and 1945.
(Carl Zeiss Jena sonnar 50 1.5, red T, S/N : 2,857,916)

I could not get more precise description on the web (I guess every site has the same source or, worse, copy each on other..)

So I turned on the body. Making the assumption the body and the lens has not been unpaired, the year of production of the lens and of the body should be close.

Unfortunately the body (S/N : C10988) is supposed to be produced in 1936-7 according to cameraquest (http://www.cameraquest.com/zconrf2.htm )

Dead end...

Lenses are removable, so there is no guarantee that when you buy a Contax RF with a lens on it, the two came together originally.
Considering the time passed, the fact that the camera and lens dates do not match is hardly anything to be surprised of.

hi everyone,

I've been learning a lot from this forum but didn't register until I read this post. Thanks to the earlier contributors to this thread!

I just got a CZJ Flektogon 2.4/35 with a 4-digit serial number of 6***, which I suppose it was produced in the late 80s' according to the origianl post.

But here is a weird thing: I found the following lens on the Taobao (Chinese version of ebay) with a 6-digit serial number "112592", but from the appearance of the lens one can easily tell it's definitely not from a time back to the 1910s'.



Here is the original link (yeah I know you guys probably don't read Chinese but just scroll down and look at the pics):

http://item.taobao.com/item.htm?spm=a230r.1.10.37.eTDhWq&id=21067792955&_u=t3ou2hsafda

Any thoughts on this?

Question why doesn't the link included in the last reply show up? where is the picture? but everything was fine when I "preview" the reply? Shocked

Because it is one of the more recent lenses. More precisely, from December 4th, 1981


I have unused Flektogon #3024, strangely it's 2.8/35mm black version for Exakta. Was that some late or special batch?

Sorry if this has been asked before but are the serial numbers stamped on the metal lens barrels (not visible unless disassembled) supposed to correlate in any way to the nameplate serial?

I have CZJ Sonnar 135mm in my mind and i think answer is yes.

Hmmm, OK. Well I have a Biometar P6, serial number 425xx. One of the inside elements was loose so I had to take it apart. Both the front and back blocks are marked with a four digit 28xx. Hopefully that doesn't mean they were swapped at one time?


PostPosted: Sun Nov 03, 2013 7:06 pm    Post subject: Reply with quote

Surely not. Just different numbering for both. But if your front and rear block would have different serial then that would be indication IMHO of swapping.

Fantastic! Thanks for the info and assurances. The two match so that's a good sign. I was a little concerned because it's actually a pretty uncommon Biometar and I had hoped the nameplate wasn't just switched out.

I read a big issue with the Rolleiflex 2.8A is mismatched front and back blocks. That's because the glass was sourced from pre-war production of the Ikoflex III. Rollei took the glass, coated it, and things got confused during reassembly. At least that's the story...Sorry for the divergence. That just reminded me and I thought it was interesting.

I just bought a Sonnar 300mm /4 from ebay
with serial number: 2731500

According to this it is 1941?
I have not seen one like it and was worried it might be of dubious origin.





Not sure if images are showing here's the URL for anyone curious

That lens was made 6.4.1940 for Contax in a batch of 100 lenses.

It seems to have been modified to fit a c-mount (?) film camera.

Thanks for your reply kds315*.

The seller claims it was an m42 mount, I will have it in a few weeks and can post info on it.
The thing that got me is no other google results look like the images of that lens.
As long as it performs as well as what other people have claimed I guess I'm a happy clam.

At the weekend I spotted a CZJ sonnar 135/4 at a car boot sale in good condition.
Since it was only £5 I couldn't resist it Smile
Checking the serial no it appears to be from around 1963-4, just like me!
Is there any chance someone could give a closer date for it given the no which looks like 68474X7 (Not got my glasses handy so I can't be sure of the second from last no. But I doubt that will make much difference!)

Thanks Mike

The photo of mine has disappeared. Here's a new one. Possibly the last one ever made?

wo, cool number

i wonder how it transpired

Cool number. Any one have a lens with 9999999 serial?


PostPosted: Thu Dec 04, 2014 1:24 pm    Post subject: Reply with quote

Which is the thread of filters for Tessars with 3,470,000-4,000,000 (1952-1955) and 4,000,000-5,000,000 (1955-1958) serial numbers? The information that I have found on the internet are contradictory.

It might be a contender for the highest serial number seen on a 135/3.5 MC, but I have a 5-digit serial number example which is presumably of later manufacture after they reset the numbering and moved away from the 8-digit serial numbers.

S/N 10,000,000 doesn't mark the last lens made, the table is just a broad range and guide to the age of lenses based on the serial number. Manufacture continued well beyond 1975, but at some point they stopped the old serial numbering system and started a new one. There is at least one serial number beyond yours on the recent Flektogon thread. I've not seen a definite statement as to which was the last of the 8-digit numbers or when the change in system occurred.

It is still a special number though.
