I suspect this lens was made by Cimko as I have a Cimko MT labelled lens that looks identical:

Here's a similar lens except labelled "Rokina" and not "Rokinon".

Here is a series of pictures of my Rokinon 135mm f2.8.
It has a similar serial number to the earlier lens shown.
It is quite a reasonable performer and I will include an image taken with it as well.

I saw you're puzzled regarding above Rokinon lens. Firstly i don't think it's too old to be Samyang. I think it's Samyang. Regarding SUN / Samyang connection (possible transition) that could be well seen on exactly this lens i don't dare saying much until further research. SUN disappeared as Japan company soon after 1983. SUN Korea was formed 1987: http://www.sunopt.com/english/info.html

Thank you for the feedback. I always thought it too old to be a Samyang - you could be correct on it being just that.
I would be pleased to see the results of any further research.
Much appreciated

The 135/2.8 is clearly labeled made in Japan. I think that eliminates Samyang. Perhaps Cosina?

Good point.
Is it possibly a Sun Japan lens?

Despite having Japan label, i a would dispute it. It resembles SUN lenses significantly but quality and final touch is different showing similarities with Samyang. I was thinking lens is made in Korea by SUN's specs. Distribution in Japan or some part of assembly still done by SUN. The same lens or at list with minor differences a bit later no longer has made in Japan printed but made in Korea. See PK Revuenon lenses for instance of this series!

Forget Cosina in this case no similarities. Slight similarities with Ozone Optical nevertheless Ozunon (also Ozeck) 135mm lenses are heavier.

This is possible event development. But i'll be happy to get opposing opinion:

Initial SUN model 1:


Later SUN model 1:


PORST / SUN / Japan type 1



PORST / SUN / Japan type 2




PORST / SUN / first Samyang?

Revuenon / Samyang ? type 1




Revuenon / Samyang ? type 2


Ozone (heavy, better made lens IMHO)

Very interesting! I didn't know there is Sun Korea. But I already have written several times that I am very confused by several Korean lenses being very similar to Sun (original Sun or Sun Japan should I say now Smile)

Regarding the OH's lens - I think it is still an original Sun version but who knows? The thicker "crown" around the rear element is quite a distinct depart from the old Sun versions.

Yes, it looks very much like the Porst/Sun lens, but without the auto/manual aperture lever.
Thanks for those images.

This is most likely a Kiron lens. They used to relabel them in Europe as Panagor or Admiral, at least the 35mm f2, 28mm f2.5 and there was a 21mm as well ... and on the tele side 135mm, 200mm and I believe a 400mm.
