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?

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? |

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. |

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 
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 |

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. |

despite from a few almost invisible cleaning marks on the front lens, it really is in a very good, almost untouched condition.

I just bought a beautiful Carl Zeiss Jena Sonnar 1:1,5 f=5cm with serial number 2,226,829. But strangely enough this number does not appear in the list.
According to the list some numbers are missing and my lens falls in this gap:
1,930,150-2,219,775 1937
2,267,991-2,527,984 1938
Is the list not correct or is there another explanation? |

Perhaps the lack of reply was because people don't know the answer.
I'm willing to speculate that if it falls in the gap between 1937 & 1938 it would likely be made around the new year...
Scanning the list most years seem to have gaps on most year changes but there's at least one where the numbers overlap. Maybe indicating one lens was being started in '24 but not completed till '25.
Certainly the numbering appears to be a simple sequential system (with occasional distinct changes) it doesn't look like the numbers are being restarted in line with a new year. So I don't see it as a reason to suspect your lens is a fake! |
