Steinheil Munchen Tele Quinar 135/3,5 M39

This lens is for SLR M39, not M39 aka LTM rangefinder. But it has short register as SLR one. I guess it's for Braun paxette M39 SLR. It's tiny and has MFD 3 meters, too long for common SLR, remind me of Voigtlander super dynarex which has 4 meters MFD.
In My Sony NEX I use extension tube + LTM-NEX adapter to reach infinity. I really like it's compact size and beautiful silver/chrome finish. Everyone will watching it :D
There's one thing that I like about results with this lens, I can see 3D in most of results than other lens, specially 135mm lens.

This lens has good reputation, it always compared to Nikon 100/2,8 E series.

Minimum focus distance is marked 0,8m, here's sample at closest focus

Sonnar 4cm/2 from Zeiss Ikon Tenax

I got only optical block of this lens. There're blades inside, but no aperture ring outside.

Here's description about the camera from wikipedia.

During the 1930s, Zeiss Ikon (ZI) made a wide range of miniature cameras for the 35mmfilm format. Most cameras used the standard 24×36mm frame size, like the Contax,Nettax and Super Nettel. However, the ability to take images in fast sequence was a popular marketing element at the time, and several fast-operating models were made. Among these were the Robot cameras as well as the Zeiss Ikon Tenax I and II. These have the smaller square format of 24×24mm, enabling faster film advance, either manually or motor-driven.^[1]

The Tenax II is a 35mm RF-camera launched by ZI in 1938. It produces 50 square exposures on a standard length of 35mm film. It has a Compur Rapid shutter, situated just behind the lens, with speeds from 1 to 1/500 second. The camera is wound and the film advanced simultaneously depressing the large lever on the right-hand side of the lens. At first it was only called the Tenax, but the following year a quite different and less sophisticated camera with the same name was launched, both designed by Otto Berning. The 1938 model is known as mark II, or just the Tenax II, while the simpler 1939 model, is known as the Tenax I.^[2] The "Tenax" name belonged to the C. P. Goerz company in Berlin, being used from 1907 on folding plate cameras and a Vest-pocket camera from 1909. C. P. Goerz became a part of Zeiss Ikon at its formation in 1926. The name was used again by ZI in the 1960s. The Tenax I was continued for a while in the 1950s in East Germany.^[3] 

The Tenax II has a proprietary bayonet lens mount as a provision for using different lenses, but only a small selection was made available during the few years the camera stayed in production. A small round window in a lateral extension on the lens barrel is aligned up in front of the camera's right-hand rangefinder window. 
It contains a pair of contra-rotating glass wedges synchronised with the lens focusing lever that provides accurate focusing by aligning the upper and lower subject section in the viewfinder.^[4]

STANDARD LENSES:

• Carl Zeiss Jena Tessar 1:2,8 f=4 cm ^[5]
• Carl Zeiss Jena Sonnar 1:2 f=4 cm

I attached it in my contax RF/Kiev - Nex adapter, works nicely.plus I can make it closer MFD, so close focus shots here like using extension tubes.

I got CZ Sonnar 50/2 LTM version, but optic is hazed so bad. So I took off the optic block, then put this 4cm/2 optic block in it. works nicely.

Zeiss Opton 50/1,5 Contax RF mount

Contax Range Finder mount (It's also called Kiev RF or Nikon RF) has some nice lenses, but it's not popular due high priced adapter to mirrorless cam. some lenses have no focusing helicoid, this 50/1,5 West Germany made too. I got an adapter made from used Kiev camera.

left is adapter made from Kiev camera

Opton means this was made in West Germany. while their counterpart was Jena from East Germany.
Like many other old lenses, this lens has low contrast character.good for B/W results.









From rangefinder.com I found interesting information. This was posted by member ZeissFan
Briefly, the breakdown of the Carl Zeiss lenses is this:

1) Carl Zeiss Jena (no red "T"): Prewar uncoated lenses in a heavy chrome mount. Some lenses near the end of World War II were coated and a few are in lightweight alloy. And some prewar lenses were coated by a third party, but these lenses in general will not have any designation on the lens ring. The earliest lenses for the Contax I are in nickel and black mounts -- very handsome and somewhat expensive. Remember, it was the Zeiss lenses that were the key component of the Contax system. Zeiss had an outstanding, sharp f/1.5 lens (Sonnar) well before Leica had a comparable offering.

2) Carl Zeiss Jena "T": For the most part, these are East German lenses and are in lightweight alloy mount. You can feel the weight difference between the East German optic and their West German counterparts.

3) Zeiss-Opton "T": Coated West German lenses in a heavy chrome and steel mount.

4) Carl Zeiss (no "T"): Zeiss dropped the "T" with these final series of coated lenses. Again, a heavy chrome and steel mount.

So Mine is number 3 version. It's heavy chrome and steel.

Color tone remind me of old print in years ago before digital age. take a look at this one
