Biogon 35/2,8 T in LTM (wartime lens)

[photovdz]

Just received it this morning... I was afraid of a JUP12 copy... but the lens is a true one...

Nr 27144466 on the ring and the back of the optical blocK... clearly Zeiss glass... small m... and so on... (the front diameter is a bit smaller than my J12)... the back lens is untouched and of the good type...

Glass is perfect, mechanics are oK... and I paid 100€ (that's why I was afraid of a fake)

After a short exchange with CB, we pinpointed that lenses from the same batch are known in BK version... but this one is not... clearly Zeiss.
So it must date from the troubled time (between 43 and 47)...

Now it's on my IIIf (looks nice with a Zeiss 432/3 viewfinder)... and I'll make a roll...

Pictures of the lens... and pictures made with the lens soon to come...

And my Zuiko 4cm/2,8 is back from cleaning too... good point to compare...

2714446 of course...

Thanks for the informations...
The subcontractor for the LTM transformation is a very relevant hypothesis... that explain why there are bizarre lenses in those numbers... The fact that the LTM mount transformation was an outside job explains why the CZJ annual report 1945-46 says "we never intented to produce LTM mount lenses before 1945"... their right hand never intented but the left hand was working for military orders...

Congrats !

I'm jaleous. About the 40. Show some pictures of the Zuiko on a camera, please, must be really tiny ....

Cheers,

Roland.

Hello!

I dig out this thread, just to say I have such a lens too.
But this Biogon s/n 2714578 (same batch as yours, Stephan) has a KMZ Jupiter 12 shell s/n 5202635. And there are BK-s in the same batch too.
So, a part of this batch must have been sent to Krasnogorsk and transformed into BK or Jupiter 12...

Note I have too a 1951 Jupiter 12 which is only a Jupiter too, as I can see...

Amitiés. Jacques.

and since I tried to take pictures with this tlens... it has a major problem of decementing of the front parts of the lens... just unusable as such
otherwise it's totally ok, number on the front matches number on the back...

do you know someone who could repair that decementing ?

John Van Stelton of Focal Point does this kind of work.

Comparing BK with WarTime Biogon LTM

 

[LeicaTom]

Odd seems that many of the surviving LTM/M39 Biogon's don't have their protective collars anymore?
Or they only have like half collars.

My US Army one had this long protective collar -

That was/is what that original factory collar looked like for all those concerned....

I have two genuine wartime LTM Biogons, plus one postwar and one more on Contax mount - no one of them have so long protective collar like yours. But it is really usefull I think - this place is highly danger for scratch. Or...maybe your biogon is not Jewish, with a foreskin?
