I was just wondering if anyone knows of a simple way to tell between I-50's that were made for rangefinders and those made for slrs?
Apart from the mounting them on a camera, as I want to be able to tell them apart while looking on ebay, as the seller may be mistaken.
Any help would be much appreciated.

| Yup, the SLR is the "pancake" lens, as the mirror housing provides the extra distance needed from the film plane. |

I-50 for rangefinders has minimal distance (on scale) 1m
SLRs - 0.65m |

I've just found a black Industar 50 lens, serial No. 6951307, labelled as M39, on ebay and I was wondering if the M42 versions were all labelled Industar 50-2, or was that a second version of the lens?
Any help would be much appreciated. |

It's just the second version. In fact there are three different types in M42. On the earliest one you can use both screw in filters and push on 36mm filters. |

Thanks for the infoMilo.
They don't like to make it easy for us, do they? So is there any chance that the black one I mentioned earlier is a zm39 version?
Could you please tell me What the differences are between the 3 m42 types
@Alex_Rus, it looks like the slr lens in the pic that SteveA posted a link to, has a minimum marked distance of 1 metre, so were some not marked 'correctly'? |

"2" is M42x1

Hello zoom, thanks for the link, although as a typical 'Brit' I'm useless at foreign languages. I do remember watching a couple of episodes of "Russian language and people" on BBC tv decades ago. I can say 'yes', 'no', 'hello', 'thank you' and I could have a go at saying 'goodbye, summer', which was the title of a sort of 'mini-soap' programme that they had in the series, to show how Russian was used in 'real life'. There were two women in it that made think 'Well, hello!'
Anyway, I understand that the '2' version is only m42, but the black lens I found doesn't have '2' written on it, and so I was wondering if it could be a zenit m39 version. |

I can describe my understanding of this "-2".
This text under the link tells the notation with 2 at the end was implemented to distinguish between M42 and M39 lenses. But it is not written when this implementation was done. Seems it was done after I-50 appiered on market.
Saying other words. If a lens has "-2" at the end you can be sure this is M42. When there is no "-2" at the end - you never know by name only. |

Some "SLR" version of I-50 sometime have minimal focus distance 1m because it was originaly LTM version.
LTM are just SLR version with "macro" ring. If you remove it, your LTM will be a SLR.
Check here : http://t.hacquard.free.fr/site1/l_industar_50.html
I think M42 I-50 are quite rare, only the last ones. But black I-50 are not rare, there are also zebra version (black body and silver aperture ring), for export (but not only). |
