    Hi,
    As the title says I'm wondering if anyone here has tried putting Sony E-mount on old film camera (Minolta or Leica perhap?)

    Hmm I think flange-sensor distance could be a problem. On slr's it's way longer than on emount and it's probably also a bit longer on Leica M though Im not sure about that.

    Yes, this is exactly the problem. The reason we can use so many lenses with other mounts is due to a very short distance from the lens mount (the ring on the camera front) to the sensor plane. This is almost always shorter than the distance the lens was designed for, so an adapter can simply add material to increase the distance of the lens from the flange. To use emount on another camera, this distance would have to be even shorter, and you have to allow for the thickness of the adapter. From the chart included in the article below, you can see that would be very few cameras.
