    Inspired by the samples seen on this Forum of the Ektar 25mm f1.4 I looked for one but I only found the f1.9 version which looks a bit different. Mine is an M-mount (two prongs, no thread) and the focus and aperture are different.

    The lens has not threads and I had no idea what the flange distance would be. I took a C-mount to M43 adapter and enlarged the hole with a round file (being aluminium was rather easy).
    Then I tested the lens at infinity and wide open while holding it in place with plasticine (!).
    After a few trials I worked out that the lens can sit almost flush with the back of the C-mount.
    Yep, almost; and that meant two attempts to get it right involving removing cured epoxy glue! (Edit 22MAR16: on a second lens that I adapted it was totally flush)

    On my last attempt I simply shimmed the C-mount (black) with two sheets of thin paper (totalling approx. 0.3mm) while resting the lens on a flat surface when the epoxy glue (J-B Weld) was curing. I now have almost perfect infinity: I have to back off the focusing ring by just 10 degrees. The focus throw is super fine and very little movement happens when the lens is focused (down to 12").
    The lens actually seems to have a 28.5mm flange distance (approx.)

    But how does the lens perform?
    Well, it's weird, but in a good way. :hmmm:
    The image circle was never meant to cover M4/3 but 16mm film, therefore the edges are utter rubbish, if one looks for sharpness.
    On the other hand the centre is very sharp, even wide open. But just the centre!
    Stopping down does improve a lot, and at f5.6 is very good with a much wider sharper circle.
    It will however never match a modern lens in a sharpness comparison, but that is NOT why I wanted this lens.
    I wanted a swirly background that no other modern lens I have can give me. I looked at Petzval but that was out of my budget, indeed :shakehead:
    Here are some quick samples, all shot wide open at f1.9

    It does however look funny and disproportionate on the Oly E-M1 :laugh1:

    Silly as it sounds I kind of like the blurry edges of a city scape image, where traditionally I would go for a stupid sharp lens instead. Centre does look sharp tho.
    Call it honeymoon period with me using this tiny new lens ;)

    I never thought that I could use this lens so much for street photography.
    Really low light, handheld with rather slow shutter speed (1/6sec)

    and a great lens for close up subjects since it focuses down to 12"
    I love how the bokeh of highlights appears as bubbles, reminding me of my Meyer Optik Trioplan

    Nice. I have one of these in S-mount, picked up along with the camera and a few other lenses in a thrift store, with the 63mm 2.7 getting the most attention thus far -- I see I'll need to quit neglecting the 25mm 1.9!

    Took another look tonight and realized I was mistaken, my 25mm is also M-mount, made in 1951; guess I need to sacrifice a C-mount adaptor and follow your example -- thanks for the detailed info and photos!

    on the second M-mount Ektar I did not allow for the "0.3mm" off set on the C-mount as I found that sitting flush was giving me perfect infinity anyway (sample variation?)
    The shaving of the internal diameter of the C-mount to accept the larger body of the M-mount was done incrementally to achieve just enough friction to let the lens sit and test.
    A drop of Superglue would keep in place to test and once I was happy I simply used JB Weld.

    Here is my try on adapting Kodak Ektar M-mount.
    I had an unused m39 Chinese adapter, where I discarded the central part and machined one from acrylic to fit Ektar.
    Here how it looks:
    adapter.
    Apart from that screw (lost the small one), it looks pretty decent.

    Here is first shot SOOC on f1.9:

    that is one very clean adaptation and factory-like look (the grub screw can be replaced, they are easy to find at the fasteners shop)
    I saw something like that from a seller on evilBay in Israel where he asks near $300 for one mounted! :eek-31:

    Small update:
    The problem of black corners was actually caused by filter holder.
    Without it it's better, that's why I converted it to lens cap.

    lenscap.

    again, a very clean adaptation. For mine, I fashioned a lens cap out of an old film canister but since I have two of those lenses I can't find a second canister that will fit. I will now look for a filter holder and do the same as you. Much nicer than my ghetto cap :rolleyes:
    What size (I know that they are numbered in #) is that cap?

    The full name of filter holder is: Kodak 285-320 Lens attachment Made in England, and it goes on the lens (28.5mm), not into.
