Compact 180mm 3.5 Soligor lens made by Tokina


Interesting - 16xxxx serial is attributed to tokina. Focus barrel etc looks tokina but I didn't know tokina produced "chrome eared" soligors.


My Chrome eared 135mm 2.8 is also Tokina: https://www.flickr.com/photos/randomdump/albums/72157709837216846/with/48357782351/

Kuribayashi Petri Penta with Orrikor 2.0/50mm


PostPosted: Sat Oct 26, 2019 3:05 am    Post subject: Reply with quote

My latest is a howitzer of a lens -- a Takumar 400mm f/4 for my Pentax 67. It is huge, has a manual aperture with 12 blades, and is regarded as optically excellent. I can't say for sure on that score because i just got it and haven't shot with it yet.

I plan to get an adapter for it so I can use it with my NEX. A 400/4 is equivalent to a 300/2.8, when considering the focal length to aperture ratio, so it should make for an interesting optic.

This is a shot of a later version -- same optical formula though, and the early and late look almost the same:

Some of the early Petri lenses have odd optical designs, this one too I think. It will have a character.
This site has interesting details on them:

While not described as such, I think it is a hybrid of a reversed Sonnar front + a Gauss.

Based on your link it could be a nice lens to hide the real subject into the background for seek and find images. Baroque in a sense.

So the Westanar 135mm f3.5 arrived and its a nice piece of glass. Aperture a little stiff and the metals a touch discoloured but I think it's performing well enough..



Also got a Praktica B100 in the post with a Pentacon 50mm f2.4 but more importantly there's a CZJ 35mm f2.4 on the camera.. 😁

1969 Schneider - Kreuznach (Durst) Componon 1:5,6/210.




I frustratingly need just one more piece of the adapter puzzle, and I can get this crazy lump up and running.

This is a great site, scroll down for the Petri lenses.

Minolta AUTO TELE-ROKKOR-PG 135mm F 2.8 from the first series circa 1959

1974 Schneider-Kreuznach G - Claron 9/240.

Probably the longest I've taken to clean the glass in a lens, even with such a simple and accessible design (6/4 Plasmat). A heavy and very resilient haze on two inner faces, two types of fungus for added interest, along with the usual detritus.

It's scrubbed up nice though, although I can still see, frustratingly, a faint haze and the faintest ghost of an outline of one of the fungi. Sometimes you have to decide, when facing diminishing returns, that it's time to stop.



I have no idea how it performs, as I need to now work out how best to nail it to the end of my camera. I'm thinking of taking a leaf out of DConvert's book and using a 54mm helicoid, rather than tubes and reducers to a 42mm.

I have a feeling I've not revived it to top performance. It was more a rescue mission than anything else. It's very compact for a 240 I must say, and it didn't need a winch to move it around.

For October. I got a Minolta Auto Rokkor PF 55mm f1.8 from Japan. Nice lens with original caps.

I also got A Vivitar SMS 28mm f2.8 MC Close Focus lens by Komine, in excellent shape.

unlike some producers who claim to be the first to introduce aspheric lenses, Heinz Kilfitt introduced an element ground with two radii. I have not been able to ascertain whether all his 90mms had that- even after mr Backs Zoomar took over.

Heard and read about that, too Paul, but also was never able to find some proof for such ....

I read it here (in German): https://photobutmore.de/exakta/kilfitt/

(quote) 1959 entwickelte er ein verbessertes Makro-Kilar 90 mit einer asphärischen Linse. (unquote)

The same text later mentions a "BI-spährische Linse" i.e. a lens with two radii
