I made one from a standard Chinese OM to 4/3 adapter and the flange from a X-Fujinon teleconverter (the cheapest way of getting a donor flange). I did this for the "Cheap Lens Challenge" when I picked up a X-Fujinon 50mm f1.9 DM for next to nothing. A fair bit of machining was required for this so a lathe is essential. To get infinity focus the OM adapter ends up pretty thin as well, so care is needed with the machining. The two parts are screwed together with M1.6 screws (the smallest size I could get screws and taps for easily). M1.6 requires a 1.25 mm diameter hole for the tap so you will also need a decent drill press.
From that thread

At the moment, the lens aperture pin is held back with a bit of PTFE. Crude but effective.
I found a simple way of locking the lens to the adapter with a small screw that can bee seen in the picture below. The screw is accessed from the largish hole seen in the above picture at about 7 o'clock position
There is a plastic baffle at the back of the lens which has a peg that fouled the adapter. I could have cut the peg off, but instead, I removed the baffle entirely. |
If you don't have this sort of engineering equipment, the only way forward will be to swap the X-fujinon flange.
