Kryss,

So beautiful...
What's the lens, a Tessar?

Cheers,

Renato

Looks very nice Smile

the name Jena when you are talking LTM, I thought denoted a lens made in the pre-war Jena factory. This lens was made in the Soviet side? Meaning East Germany, 1947 +?

The only LTM Jena lenses were made during ww2 as Leitz were unable to keep up with the production numbers required. It was these lenses that the Russians copied to make their LTM Jupiters. All Zeiss did was to remount their Contax lenses into LTM barrels. These wartime LTM Zeiss lenses are rather rare and were often in surprisingly poor quality aluminium barrels.

I'm not sure what the Russians copied to make their Industar 3.5/50. There was a pre-war Zeiss Tessar 3.5/50 for Contax, but the Industar doesn't render at all like that lens so maybe the Industar is a copy of the Leitz Elmar?

I think that the industar is not an Elmar but a Tessar.

The Industar-50 is a tessar(the aperture position is placed between the 2nd element and the 3rd cemented group). It is also mentioned in the archive of KMZ.

According to this, the pre-war Industar-10 is a copy of the Elmar but the post-war Industar-22 is a copy of the Tessar:

Great results Kryss from this lens - indeed.
I have a pre-set version - no Red T - and I don't think that it is as sharp as yours wide open, but it does render very nicely.
This one is with a small extension tube to give the shallow DOF.
Cheers
OH

Thanks OH,that is a very nice shot too,I have to put short extension tube on mine if I use it on one of my DSLR's or it hits the mirror.

Mine will operate without the extension ring - but to render the OOF highlights, I had to add it.
Here it is on my X-E1 and the extension ring is between the adapter and the lens.
Cheers

Thanks Calvin.
I thought maybe that it was, as its serial number puts it in the next batch after Kryss' lens (around 1955 I think).

Very nice. I just got the exact same lens, but the focusing ring is basically immovable. I hope that it just needs some lube because its otherwise in mint . If it works out, I hope my copy is as sharp as yours. I really like the last shot.

Are you sure its not a preset ring stopping the movement?
I bought this lens with preset ring as "broken - focus ring stuck" for peanuts, because the seller did not realise its a preset.
You have to pull the preset ring OUT move it you see...

Rudolf,

Just for a matter of curiosity, I had the chance to by last year 2 analog cameras considered broken by the sellers, with the shutter not firing, and all I had to do was replace the batteries,

Very Happy

Cheers,


Renato

With these tessars, You had to push the read pin back in to snack the aperture open?

I remember trying to use it and it was just annoying.. I'm trying to think.. Oh pulling down and selecting the aperture it would stay, but to open it all the way again I could turn the whole thing to the right, but then the aperture wouldn't engage until you pushed the rear M42 pin back in. I think I used to try and 95% turn it around to re-focus etc etc then allowing it to remain "stopped down" ? I couldn't work out a way to keep the M42 pin depressed either as simply holding it in the entire time didn't fix it..

There was an earlier one that came with a Praktica IV, no a FX2 that was half the size and had a "conventional" non-automatic aperture mechanism.

I should have never sold that lens.. Embarassed

Oh, an d yes all the ones I've had had been jammed shut more or less, simply fiddling with them bought them back to life Wink

Hi,

I have the same camera model. maybe more beaten then that,but works as intended - M42 mount and I can screw-in many lenses,
There is a loupe inside the "box" shade for the ground glass for better focusing, nice camera,

Cheers,

Renato
