All Distagons in the Woltche article use aspherical elements. Maybe they were prototypes considered unfeasible for commercial production, or were cine lenses for 35mm format, I don't know.
EDIT: I see now that Zeiss had a cine 18mm F1.2 lens. You can buy one from eBay:
http://www.ebay.com/itm/Zeiss-Arriflex-Distagon-18mm-f-1-2-T-Super-Speed-PL-Lens-For-cine-movie-Camera-/121538168881
And this lens set could be interesting for those that love fast Zeiss lenses: 
Carl Zeiss 16mm F/2 - Front and rear glass excellent condition.
Carl Zeiss MK III 25mm F/1.2 - Front and rear glass mint condition.
Carl Zeiss MK III 35mm F/1.2 - Front and rear glass mint condition.
Carl Zeiss MK III 50mm F/1.2 - Front and rear glass mint condition.
Carl Zeiss 85mm F/1.2 - Front glass excellent condition, Rear glass has tiny cleaning scratch.

The corresponding 1977 Zeiss patent (Fischer / Glatzel / Jahn / Zajadatz) lists twenty different examples for fast wideangles, among them some with 78° angle and a speed of f1.25, and others with up to 50° angle and f1.03.

An improved version of the CY Distagon 1.4/25 is available now ... the Milvus 1.4/25 shares the same construction principles with its ancestor from 1976 (here the lens section of a 1.3/35mm prototype is shown; sadly I didn't find the lens section of the CY Distagon which was available on the Zeiss webpage some years ago):
The above lens basically consists of a Gauss design master lens (right part "O") and a Newton Finder (left part, "NS" = "Newtonsucher" in German). The Newton itself consist of a negative front part ("NN") and a postive lens ("NO"), as you can see from the simplified diagram of a Newton Finder (image from https://www.spektrum.de/lexikon/optik/sucher/3305):
The fairly recent Zeiss Milvus 1.4/25mm uses exactly the same principles. Its construction certainly is based upon the Glatzel patent from 1976!

Hello everybody,
I stumbled upon this topic when looking for information on Zeiss prototype lenses.
Wow, that 25 and 18 look absolutely terrific!
On a side note, I wonder if any of you have found other prototype versions in the market and if it's actually worth it to buy them (since I'm not sure if their performance is on par with the commercially released copies).
I say this because I recently found a Zeiss Distagon 28 f2 for Contax Yashica mount but that says "HFT" on the front. It also has a serial number of 25XXXXX which seems to be about right for prototypes.
Maybe it's a prototype version for taking the lens design from Rollei QBM to C/Y?
If any one has any thoughts, I'd love to hear them.
Regards |

It seems so. Might be the 1.2/18mm Super Speed Distagon for the Arriflex.
