Hi All
I have come across an unusual little lens, not much about it on the internet. It is branded Astronar & is 135mm f:3.5 16 aperture blades with a threaded mount. The mount is very close to m42 but has a slightly finer thread? In fact it will screw into my m42 adapter by a few turns but then stops. Any ideas as to what I need to adapt this to E-mount & any feedback on this lens would be great?
Thanks Andrew |

Could be a T mount (42mm x 0.75 pitch). Regular M42 is 42mm x 1mm pitch. Welcome to the world of T mount and preset lenses! You can easily buy a T to NEX adapter. |

Most certainly a T-mount -this is a universal mount system, still in use, that has adapters that screw on to that M42x.75 thread.
There are T mount adapters for every camera mount under the sun.
Astranar was an importers brand used by Sterling Howard of Yonkers, NY
Very likely made by Kawakami (Kawanon) as there are many of these seen as Astranar or other Sterling Howard brands, but there are 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. |

I have just ordered the T mount to e-mount adapter, I have managed a few shots with the lens attatched to a m42 (Just a few threads & it stops) the pictures look really promising it looks like it will be a good find.
Pics are very sharp & the out of focus areas look great. Looking forward to the adapter so I can test it properly. |

Usually you can't go wrong with 135mm lenses. I've recently collected quite a few. The T mount adapter has an inner ring which can rotate when loosing the three tiny set screws. This way, you can adjust the lens so that the aperture numbers are facing top. |

I think I am going to be very happy with this one, will try and find out a bit more about its history while I wait for the adapter. |

If there is an E at last of the serial number, it could be a Sankor made lens. Sankor had many such 135mm lenses rebanded, probably most of which are 135mm/2.8. Hopefully you can have a photo showing the front. Similar to this one?

I am not sure if it is their earlier lenses, as later Sankor lenses seem to use Italic font for DOF scale, aperture numbers, etc. |

Thanks, it is exactly the same as the E-Bay link, my serial no is a bit higer starting with 78xxxxxE. One thing I really like is the size of the lens, it is only about 100mm long the smallest 135 I own so far. I will have a look at Sankor lenses to see what more I can find out. |

When I got my first preset, a 135mm f/2.8, I had the same feeling. The lens is so small but a good fit to mirrorless cameras. I have yet tried a lot of Sankor lenses. This is the name I heard from this forum then started to notice it. Enjoy your 135mm. |

I will post some pics soon as the adapter turns up, I think it will get a lot of use due to the small size alone, it will easily fit in my pocket it is about half the size of my other 135’s. The shots I got with it just sitting in my m42 adapter looked really sharp warm colours & interesting backgrounds. |
