Jupiter 12?

It is a m39 mount lens and goes too far in. I was also considering this lens, since I also own a FED 2, but after some research I found out It's not possible.

Optically it would be plausible but there just too much stuff in front of the sensor. Like the filter/cleaner glass and it's protection.

 

Wide-open, It is not a very sharp lens. It flares a lot. If you want a small 35mm lens, non-retrofocus design, look at the Canon 35/2.8 in LTM.

 

The jupiter 12 does do some nice BW film shots. It's shortcomings give the images something extra in my opinion  

But for micro4/3 you definitely need something else.

This is not possible without any optical elements, since the distance to the film/sensor plane, has to be the same as in the original camera. Otherwise you cannot focus the lens properly… And there aren't any such optical adapters on the market and if there were they would be very expensive or of crappy quality, like cheap tele/wide converters…
