    The lens was taken from a Minox 35EL and glued into a M4/3 body cap.

    I had a Minox 35GT, back in the 90's.
    This lens is fabulous.
    Well done!

    I only discovered this lens recently and refitted it to MFT via a C-mount adapter

    I modified the minimum focus distance to have a closer reach by removing the focusing collar up front and cutting away the "helicoid" travel stop in the groove.
    The focusing action/travel can be adjusted by unscrewing 3 small screws and then grabbing the front element and focus it to infinity (while lens is mounted on camera) and then replacing the cover and set it to infinity mark.

    I used a step-up filter ring 34mm to 37mm to cover the gap in the C-mount adapter and give the lens a clean finish.
    The distance of the lens from the sensor (Back focus) is perfect if the lens is simply placed and secured on a C-mount adapter. I glued it place with epoxy glue (JB-Weld) and then adjusted the focus (as described above)

    The lens is tiny but still punches above its weight. It's no M.Zuiko but it's not a dog either. Probably better than your average cheap Russian adapted lens.
    Fist test samples show OK-ish infinity, not much flare/glow and a peculiar bokeh in the speckled highlights when stopped down a bit (f4-f5.6)
    Samples coming soon...

    OK, let's get sharpness at infinity out of the way; something that I don't care that much about but means the world to some...
    OOC converted from RAW to jpeg (with Fastone), no tweaks
    You can click on the images and have larger magnification, if you wish

    at f2.8
