This is the Japanese-made "Exaktar" for the Twin-TL - M42 version
This was a Cosina-made lens for a Cosina made body for West German Ihagee.
http://forum.mflenses.com/exaktar-55-1-4-m42-from-cosina-made-exakta-twin-tl-t77335,highlight,%2Bexaktar.html
In their dying days of the late 1970's both East and West German owners of the Exakta brand licensed it to Japanese makers, or perhaps even European importers. And at least a couple of Exaktars have turned up, that I know of, made in Korea.
By that time even a 7-element 50-55/1.4 lens was quite generic and probably could be sourced from a great many makers.
Sankor was a house brand used by Nissin Optical I believe, better known for cine and anamorphic lenses.
Several lines of SLR lenses also from at lest the early 1960's to mid-1970's for sure, but they faded away. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

The mount looks like M42 btw.
There were plenty of cheap importer-brand cameras by the late 1970's.
Most were M42, and later nearly all were in PK mount.
Lots of them were made by Cosina, but there were others too. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Probably not multicoated.
Period I would put as late 1970's.
Made for generic M42 mount camera.
Could have been made by Nissin/Sankor, style is not similar to Cosina which would always be my first guess for these kinds of things.
BTW, a picture of the "top" of the lens would help a lot. Some of the common generic makers often give away their origin by the design of the DOF scale, etc. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Looking around I find very cosmetically very similar lenses made for the Ihagee (West) brand.
These are in M42, there may be very similar ones in old Exakta bayonet for the rebadged Exakta EDX series that is a derivative of the late Topcon RE 200/300 - which was not made by Topcon, but I think Cosina.
The M42 versions seem to be very common in the German market.
Look for "Exaktar" on ebay.
Here is one just like yours

Here's a Sankor lens I own, in this case a 2.8/35:

The lens is different of course, as mine is about five years older and from a different manufacturer.
I just wanted to show that there were many Japanese-made lenses using the Exaktar brand, from several manufacturers. In most ways it doesnt really matter who made them, the designs were quite generic.
Its probably very similar, if not quite identical, in optical design, as Ian says. I'm happy to agree with Ian that yours is probably a Nissin Sankor lens.
Sankor was a trademark used by Nissin Optical, as Pentax was used by Asahi and Nikon by Nippon Kogaku. Of course these companies later renamed themselves after their trademarks as many others too. Nissin did not. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Interesting, here is my --E Exaktar 300/5.5 focus ring. Ian, when do you think these are manufactured?

It's distance markings are identical to my Porst color reflex 55mm 1.4. Probably a Cosina made version of the famous Tomioka 55mm 1.4 design. I have very mediocre (which is quite a feat to make a sub par 35mm lens :p) Exaktar 35mm F2.8 which is made in Korea. _________________ pentaxian |

There is no 'famous Tomioka design' 1.4/55, it's just a copy of the Zeiss Planar 1.4/55 for Contarex. The most expensive part of lens production is the design phase, so there was a lot of copying.
The Zeiss design dates from 1959 and the patent on it had run out by the early 70s, so other makers were free to copy it and they did. There may have been some official o-operation between Zeiss and Tomioka that lead to this copying. The Contarex Planar 1.4/55 was in production from 1961 to 1970. In 1974, Tomioka 's parent company Yashica and Zeiss began a business relationship so there may have been some technology transfer. Zeiss introduced the much superior Planar 1.4/50 in 1974 so it makes sense that they would have given the old, obsolete 1.4/55 design to Yashica/Tomioka - Zeiss weren't going to use it anymore, so why not?
The OP's lens is a Sankor, not a Tomioka or Cosina. However, it may well use the same 1.4/55 design. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

More than likely the same, just recalculated for different glass types as the Zeiss original used Schott glass and the Japanese used Japanese glass.
Marco Cavina's diagram will be pretty accurate as it's taken from the original patents, the 'side of the box' type diagrams will be somewhat less accurate. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

This is quite an interesting piece. It brings out my speculation of transition from Sankor Japan to Samyang Korea. There is strong similarity with early Samyang series like on photo bellow. The lens of question is certainly a Tomioka clone. The design could be Zeiss copy as Ian suggests but there is big difference in design copying and real production. It certainly was not not economical for Sankor to produce 1000 (or less, it is quite uncommon) pieces of such lens. This goes for several minor Japan brands at the time. So most probably the optic was ordered at Tomioka, body was partially supplied by Cosina, whereas some distinctive features like ugly grip and label were supplied by Sankor itself. _________________ ---------------------------------
