I got this in a job lot and google seems to suggest that PENTOR is a branded version of CHINON lenses. Only mentions of a 100mm or a 28mm, but no mention of 35mm.
Does anyone recognise this as a CHINON?
Couple of samples taken this morning. Full set HERE
Seems reasonable on a SHORT(!) tube

No-one recognise this at all?? Maybe Pentor manufactured rather than badged? |

I have a Pentor 300mm 5.6, but its design is not alike your lens.

I've seen Photax Paragon lenses in this style too. And Palar.

That auto palalr does look extremely similar, but optical layout must be different because it's f3.5 and my pentor is f2.8??? |

Yes, I have seen references to Pentor being a Dutch concern. I know they had branded Praktica camera bodies, but from what I have seen on the net, most seem to have been sold with Pentacon or Praktica lenses, rather than anythin Pentor branded.
No-one is jumping up and claiming my lens as a CHINON though, so still no further forward with identifying the manufacturer. Lenses actually marked PENTOR certainly don't seem very common though, especially in this focal length. A half decent performer though, to my eyes. |

Woodrim : will do
So, the 2 lenses are in pristine condition (almost new, no wears, dust or fungus, focus really smooth). The 71 years old seller was suprised that I bought 2 lenses he had and not his Practika camera with 50mm 2.8 (or 3.5, don't remember). I said that those kind of lenses can work with nowadays DSLR.
Only one drawback for the 135mm f2.8 : thought that baldes were stuck @ 2.8 but after dissasembling (again, see my Kaleinar story ), the problem is that one of the 2 springs that controls the blades mecanism is very tired. It seems that it's due to too many years where the lens was waiting in its box, wide open.
I can't post samples now because I thought that I had the right adapter for my Nikon body but I was wrong. Mine is a T mount adapter, close to M42 but It won't work.
So, I see many adapters on the Bay : with or without glass (for infinity focus). I red that ones with glass fix the focus infinity but glass isn't quite so good. So, many prefer without glass for better results. Now, I have to wait almost 3-4 weeks for the right adapter to come from China.

Yes, I have two Photax / Paragon lenses - 28mm & 135mm - in very similar style, but I think mine are Cimko lenses with the asymmetric green diamond as the focusing mark - unlike the red 'thermometer' mark on this lens. But the straight knurling on the focus ring is something I've only seen on Photax / Paragon - but I could be wrong on that point. _________________ LENSES & CAMERAS FOR SALE.....

I received my M42 to Nikon adapter today (one without glass).
First test with the Pentor 35mm f2.8. Focus depth is very short (from above 30cm to 100cm max).
Test @2.8

Test @F4.0
No post-processing, only RAW to JPEG conversion.
It's a shame that focus depth is so short. I'll give a change to a Kood adapter with glass, it seems to be the best among them.
I'll test the Pentor 135mm stuck @2.8 tomorrow but it appears that the focus range is larger than the 35mm one. _________________ Nikon D7000 + Sony NEX-3 + Vivitar 24mm f2, Rexagon 28mm f2.8, Pentor 35mm f2.8, Konica Hexanon 50mm f1.4 + Nikkor 50mm f1.8 AI, Helios 44M 58mm f2, Jupiter-9 85mm f2, Helios 100mm f2 from T3C-2, Kaleinar 100mm f2.8, Makinon 135mm f2.8, Vivitar Series 1 70-210mm f3.5 |

Looks excellent! Is your lens is identical to the one in the first post? |

Globally, yes but :
- mine says 'Pentor Automatic 1:2.8 f=35mm' and filter diameter is 55mm.
- the focus grip is different
- the rear lens barrel is also different

Exactly the same as the Revuenon:

Just the beauty ring is different, it says Pentor and not Revuenon.
Btw, I like this lens. (Have the Revuenon.) |
