Different from the 85mm f1.5, here's the little brother : the T3C-2.
It seems to be a 100mm f2 (constant, no aperure ring, only focus ring). Only information that I've found was here : http://pentaxslr.eu/Forums/viewtopic/t=76/
Here's mine, in mint condition :
Some samples :
I think I know why the focus field is curve when ring is set to the closest focus distance. In that state, the front barrel is a little loose and thus, front lense is not perfectly alligned with rear 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 |

Wow, it looks very good.
The barrel though is a bit dull |

Apertures are different. Kaleinar is f2.8 and the "apparently" Helios 100mm is a constant f2.
Wide open, the Kaleinar is sharper but lacks of contrast. I would say that they are good but different.
DOF curvature seems to be fun with the Helios but I can't test that for now (won't focus to infinity with my Nikon).
I will try to shoot same subject with both and convert RAW to JPEG without post-processing. _________________ 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 |

Meanwhile, i was surfing on an italian site for used stuff and i spotted a night vision device with what seemed quite an exotic lens on it.
Luckily, the seller has photographed the paper that reports the technical data of the lens.
http://www.subito.it/sport/visore-notturno-asti-37511594.htm
I don't know if the lens is fixed or it can be screwed off, i asked the seller.
100mm f/1.5 looks interesting though. |

20-30eu as it's interesting but with no aperture it's not that useful, so for me, worth less than a decent 100mm lens. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I have found this info:
http://www.npzoptics.com/catalog/night_optics/
where you can see the newer version of it, called "TZS-4".
The producer is Novosibirsk Instrument-Making Plant and the lens is indeed a 100mm f2.
Lens design would be interesting (elements/groups). _________________ Best wishes, Wieland

I'd buy one as well for 10 euros, even for 20 probably.
Its bokeh is so unnatural that looks like it has been processed in post production.
Nice rendering though. |

I like this lens from what I've seen here. It seems to have a greater depth of field than the Cyclop resulting from the smaller aperture and despite the longer focal length. Some of the photos have a good 3D appearance. How and where can I find one? _________________ Regards,
