    Hi guys,

    I am planning to buy an Industar-69 28 mm f/ 2.8 and Industar-50 lenses for Olympus EPL5

    - so then I need just any m39 to m4/3 adapter from these ones? and they will fit without any issues?

    if so, which one cheapest and smallest you can recommend?

    - there is a two 50mm lenses: Industar-50-2 50 mm f/ 3.5 Lens and Industar-50 50 mm f/ 3.5

    what do you think which one is better?

    Hi, i have industar 69. It is m39 screw mount but with a little bit different/shorter/ working distance. I needed to ask a friend to do for me a separate M39 adapter just for this lens. The other possibility was to modify the lens. A normal m39 adapter will not work for that lens. You can use it but with no infinity focus.

    I think the 50-2 is for a M42 mount and the plain 50 is for the Leica. I have the 50-2 with the M42 adapter. the pictures are ok, but they are almost always hazy and need correction. Shipping will probably cost quite a bit more than the lens.

    As iliyanb pointed out, the Industar-69 will fit with a standard M39 adapter but you are unlikely to be able to focus to infinity. Fortunately, modifying the lens to infinity focus is very simple:

    The "pancake" style Industar-50s were designed for the Zenit SLR and require an M42 adapter with an M39-M42 reducing thread that adds over an inch to the register distance - you can't compensate for that by adjusting or modifying the lens. But the collapsible Industar-50s work just fine with a standard M39 adapter and present no infinity focus issues. Here's a comparison of the common collapsible versions

    thank for responses!

    which adapter do you recomend to buy? or doesn't matter, all the same?

    how about these lenses?

    looks like they are for m39 mount? or still need " an M42 adapter with an M39-M42 reducing thread that adds over an inch to the register distance"?

    Industar-69 doesn't have to be modified. You can modify the adapter itself. It's easier and not so risky. I did that and my lens focuses infinity. The description is pretty basic, but I hope you'll get the idea.
    Any adapter would work, but it needs to have the inner M39 ring removeable, so you could cut it.

    In the description you have

    If it's for Zenit it might (doesn't have to, unfortunately!) be typical M42. There were few models, like Zenit 3M, that used M39 thread with flange distance close to M42 flange. I have one of those.
    If it was designed for Zorkiy - it's typical M39 (Leica 39, L39).
    This one with conversion seems interesting: On MFT camera you could just get M39/L39 adapter and have a pretty small lens :)

    The safest solution (as I think) is buying M42 mount Industar, but that'll make lens larger. If you don't want to play safe, get a L39 version and hope for best!

    As an alternative the Industar I-61 is very common and very cheap. 52mm at F2.8, so not an F2 but still ...
    And the Jupiter-8 does F2 at 50mm and is also common and cheap and small.
    No potential problems with infinity focus on these two in my experience.

    I've always used Rainbow Imaging adapters. I've found them to be well made and have the advantage that the M39 mount can be rotated within the adapter, so you can always get your lens right side up once mounted on the camera.

    As far as I know, all of the "pancake" style Industar-50s have an M39 mount, but they require the M42 adapter with an M39-M42 reducing thread to give the correct register distance. If you mount one of these lenses with a M39 adapter, it won't focus because the lens is too close to the sensor. Maybe there was a pancake version designed specifically for rangefinder register, but I've never heard of that.

    Eugg, one of my Jupiter-8 improved significantly after I took all the lenses out and put them back in all clean and proper... just saying.

    purchased an Industar 26m 50mm 2.8
    despite I got an OM 50mm 1.8
    but this lens with adapter is lighter and smaller
    not sure about IQ, I am not a pixel peeper, for me looks ok
