Schneider-Gоttingen Xenar 1:4,5 F=18cm Review
I pick up a rare lens Schneider-Göttingen Xenar 1: 4,5 F = 18 cm. Judging from the name of the branch was made by Schneider in Goettingen.
The lens is well assembled, build quality compared to other lenses of these years on top. It is a heavy metal cylinder threaded behind, which is attached to the camera.
Judging from the constructive, it is some special facilities, not for normal shooting. I did not find detailed information—optical design, like all Xenars, 4 lenses in 3 groups (Tessar design). The lens has no aperture, and the aperture ratio is f = 4,5 at 180mm focal length. But there are also variants with the insertion of four diaphragm holes.
Variant with insertion four diaphragm holes
My lens has serial number 18 666. This number has introduced me to some confusion. No, not because there are three sixes, but because according to official information, Schneider serial numbers, date of manufacture of the lens corresponds to 1919 or earlier. But at the same time, there is information that the production of lenses under the brand Xenar began in 1927. Hence, the conclusion was that the branches had their numbering, or it had lenses for specialized or military equipment, as was the Zeiss. Maybe someone has information about this; I will be grateful to share it with me.

So I mount the lens on Nikon D3100 using the focusing helicoid and set of extension rings. About how to mount large format lenses on the digital camera, you can read here. These are a few examples taken at the Nikon D3100. My lens has substantial rubbing on the back of the lens, therefore, because maybe weak contrast. Almost all the photos were significantly tightened in the RAW converter.
The first thing I liked about the picture, it's character.
Also, the lens renders beautiful Tessar-like bokeh.
Sharpness is not bad, but it seems to be a little glow because of scuffs on the back of the lens.
But all large format lenses are a little bit soft on the digital camera because it has a low resolution for small format.
And a couple of examples of people. So far, they could not fully take pictures of people.
There are interesting halos around highlights water like meniscus lens.
Schneider-Gоttingen Xenar 1:4,5 F=18 cm is an interesting vintage lens. Yet to understand its character.
