Hi, I found an old lens in a antique shop. The guy in the shop says the box is original which I don't think so. As a big fan of silver lenses, I bought it. It is M39 screw mount and able to work with my Olympus E-510. Does anyone seen or knows about this lens ?

It got full set , metal front cap , metal hood but no rear cap.



It says E Krauss Paris No 150517 Tessar Zeiss 1:3,5 F-7,5cm



The rear



The side showing the heliod and M39 screw mount. The lens will screw backwards but luckily will not hit the mirror.

Very interesting.
I think it is a RF lens.
The Helicoid retraction is to activate the RF arm in LTM cameras.
Chris it's time for you to buy a LTM body Laughing

You have an unusual piece.

Krauss was an old French company that licensed Zeiss designs, like Bausch&Lomb in the US. I am used to seeing Krauss-Tessars from the brass-lens era, 1890-1920, I never heard of Leica-mount stuff under that brand, though I am certainly no Leica expert.

It doesn't seem that your lens has barrel markings. If it does not have a focus scale, it may be that this is actually a Krauss lens taken from some other camera and mounted on a focusing Leica-mount as a custom job ? If so, its a excellent piece of work.

Oh talking about that, the guy showed me his hidden stuff, working Zorki 6 with Industar-50 chrome !

I am considering that one though. Laughing

Hi

Thanks for the detail explanation. The mount that holds the main part of the lens looks crude though. When I took photo with it, the photos turns out "hazy" or "smoky" but the lens glasses are rather clear except for some small dots. I suspect there is light leak somewhere.

probably taken out from something like this

then machine a mount and heloid for the lens ?

Yes, that kind of thing.

I know that Krauss made lenses for plate cameras and what we would today call medium-format (6x6, 6x7, 6x9 cm), also movie lenses like that one on ebay.

Yours may be designed for medium format or maybe even an enlarger.

Your hazy result may be because of reflections inside. I understand that this can especially happen if a lens was designed to cover a large format and the lens mount doesn't have good internal baffles. Maybe you can add some to the inside of the tube ?

Nice find! Very Happy

I hope to see the results once day Cool

Don't you just LOVE antique shops and the treasures they conceal? Very Happy

what can i use for internal buffer ? Initially I am thinking of using electrical tape but that part is a moving part so I think it won't work. Rolling Eyes

Yes I totally agreed since there are some many stuff piling on top of one another, you won't know whats being buried underneath ! Laughing

Several things, possibly -

Electrical tape is shiny, so thats not an improvement, unless the inside of the tube is shiny brass or aluminum.

Some things to try

- black felt
- black colored paper
- Black sticky-backed foam (like for light seals)

If these are not good enough, you can also try making rings made of black paper and gluing several of them to the felt/paper/foam

Beside getting this lens, I got the Vivitar 400mm f5.6 at super low price. The problem is the aperature ring not working, front most glass n inside front glass had fungus growing and center element is dusty. I also succeed in persuading the guy to give me the Jupiter-11A as a gift since I bought from many times. The Jupiter-11A only front most and rear most glasses are dusty, inside alright and I had it running ! What I love most is the perfect round iris formed by the blades ! Laughing

If the Vivitar is the preset version it is easy to fix. The front group screws off from the part with the diaphragm.
