An owner charges for that lens 220 euros. I am steel in the great doubt, whether it is worthy to purchase it. Confused

Well, I didn't obtained it yet. Still in some doubts.

For me 220 euros for it looks little too optimistic price.

Well, I met the owner today, did the additional picture of him upon f/1.8 For the last look and the final decision.




When he agreed to take $235 for it, I decided to grab it at once.

Still I think special , soft focus like , soft focus lenses are rare and their cost is much higher.

I discovered description of the lens:

The word mark Tachar was registered for Astro-Berlin in 1924. Lenses based on German Patent No. 440229 from 1924 [34] and US Patent No. 1,540,752 were sold under the name Tachar . These are lenses of the type of an extended, four-lens Cooke triplet . As with the Tessar , another lens on the camera side is inserted; the two rear lenses are not cemented, unlike the Tessar.
Lenses manufactured according to these patents were also offered as Pan-Tachar 1: 2.3 with focal lengths 100 mm, 125 mm and 150 mm. They could be used cinematographically for narrow and normal film recordings. Post-war models had a maximum aperture ratio of 1: 1.8 with a focal length of 150 mm.

https://de.wikipedia.org/wiki/Astro-Berlin#Gauss-Tachar

Really something very unusual - four-lens Cooke triplet with the maximum f-stop in 1.8! It HAS to be soft, and not only at the full opening.
Looks that the production had been the very limited one. It is hoped then, that the quality of it should be really good.
