Nokton is Ultron (front group is not cemented), while Mamyia 55/1.4, Tomioka 55/1.4, Berger's Planar 55/1.4 and even CZJ Pancolar 55/1.4 are 7/5 Planars (1-2|2-1-1) - just like Biotar with one more element added in the rear group.

Thank's No-X. What about production? Nokton doesn't look so much as Mamiya SX model but like this Auto: http://www.clubsnap.com/forums/showthread.php?p=4377028

Jiri and Henry,
Thanks for the information, here is the lens I got. To me, the structure is more like Porst and seems like cosina did product some 55/1.2 lenses under the name "cosinon". Googled this question and seems like there is only one guy in pentaxforums asked this question and did not get very clear answer. But do say some people in Japan, China and Korea selling this lens......
Anyway the performance is more important, will test it as soon as I got my camera back 
Sorry for off the topic and please continue,

I only know that

I hope be usefull to you.

Do you know which design 1.4/50(55)mm lets you come closer to the object? It could be a nice way to differentiate producers too.

As I had some doubts that the Porst 55/1.2 PK could be using the same formula as the Tomioka 55/1.2, I opened mine:
This is the rear optics of the lens. On the right the outer rear element, on the left a block which is behind the diaphragm (diaphragm should be on top of it). This is a block of 3 elements, including two cemented ones (the black line is between those two elements).
Verdict: 4 rear elements, including two cemented ones. With the 3 front elements that is a total of 7 elements and not 6, which points to the fact that it could indeed be the same formula as the Tomioka 55/1.2.

Some 1,2/50-55 lenses have 7 elements. But we have to see if the distance between elements, class and curvature of glass, location of the blades, etc, are the same too.

I'm currently pretty intrigued with Cosina-made all-black touch-radioactive Mamiya/Sekor 55mm F1.4.
Just as I've guessed from Flickr shots, it is not that good when it comes to carrying bokeh quality into the distance, but relative close ups are ranging from ok to impressive.
Inside, it's a solid build too.
My question is: was there ever a multicoated 55/1.4 by Cosina? (under any branding)
I'm aware of multicoated Tomiokas, and Mamiya-made 55/1.4s are likely all multicoated, but I'm interested in this exact optical block.
I haven't found one so far, but it was produced in so many shells and under so many brands, I might be missing some.

and here a Super Carenar: http://m42lens.com/m42-lens-database/1367-carenar-super-carenar-mc-55mm-f-1-4-16
Here is a post of a Tomioka made Multi coated Chinon and A single coated Cosina. https://www.pentaxuser.com/forum/topic/porst-and-cosina-55mm-f-1-4--m42--50205
The Cosina multi-coateds don't seem to have the distinctive green coating layer.
There is a lot of confusion on the Internet over what is Tomioka and what Cosina. The main difference in probably the aperture ring. Lenses with red diamond focus marks are probably always Tomioka. If it has a Lolipop it depends on the aperture ring. I think Cosina and Tomioka problaby coöperated. Their are Tomioka branded Cosinas. Probably Tomioka glass in a Cosina body.

Is there a sure way to tell if is something is MC or not?
Among the many 55/1.4 Reuvenons that existed I think just these two were by Cosina:
http://m42lens.com/m42-lens-database/266-revuenon-auto-revuenon-55mm-f-1-4-22
http://m42lens.com/m42-lens-database/554-revuenon-auto-revuenon-55mm-f-1-4-16-v4a
Is yours one of these?
The Revuenon labelled as MC is definitely Tomioka.

Looks like on the internet people are counting reflection colors while shining flashlight into the lens.
Using this method, two supposedly SC lenses I have (Mamiya 55/1.4 and Helios 44-2), indeed have only two color reflections.
But my pre-MC Zuiko 100/2.8 has 3-colored reflections. So I'm not sure how accurate this is.
Could be that I'm in possession of a non-MC-labelled Zuiko from an early multicoated batch, or this coating detection method just doesn't work.
Having more SC lenses would have helped, but mine are overwhelmingly multicoated.

OK, I have two.
Neither is marked MC, but the coatings look multicoated not single coated.
Both have the flat rear element of the Tomioka design

So it is a v4b by m42 database classification: http://m42lens.com/m42-lens-database/266-revuenon-auto-revuenon-55mm-f-1-4-22
I'd say the left shell was made by Cosina.
I see some tell-tale DNA of distance scale, markings, fonts and shape of the A/M switch, which implies my Mamiya/Sekor was made by the same company.
This does not guarantee the optics to be the same, but the shell for both was made by the same people.

So it is a v4b by m42 database classification: http://m42lens.com/m42-lens-database/266-revuenon-auto-revuenon-55mm-f-1-4-22
I'd say the left shell was made by Cosina.
I see some tell-tale DNA of distance scale, markings, fonts and shape of the A/M switch, which implies my Mamiya/Sekor was made by the same company.
This does not guarantee the optics to be the same, but the shell for both was made by the same people. |
I think both Tomioka but different body design. The Cosinas have an aperture ring that protrudes over the focus scale with a cut out of about a third of the ring for viewing the focus marks. I Also have a Yashinon-DS 50mm 1.7 with an identical rubber grip to the left lens (Yashica owned Tomioka). The right lens seems to be a Revuenon or maybe Chinon. What is the branding on the left one?

That lens literally screams "I'm Cosina!". It's like 268% Cosina. At least.

I think so.
The DOF marks are in the Mamiya (cosina) way.
The right one has tomioka's marks. |
