A more robust version now with a Fuji-X to C-Mount-adapter. I had to widen the opening a bit to fit the diameter of the second flange on the lens. It seems to be at, or at least close to infinity focus this way.
Though maybe not as appealing as the 30/1.7 this is a nice tiny lens with an interesting swirly kind of bokeh (not very prominent in the following example).

quite an old post do I hope you still have the lens!! very nice conversion!! I noticed that you have a lot of shiny bits on the back of the lens, I've done a couple of conversion to other lenses and I noticed a big improvement to image quality if you paint them black.
the stray light bouncing off them always can cause the pictures to look a bit washed out and remove contrast.
just to add in for anyone that comes across this post, I found the yashica electro with its 45mm 1.7 lens a very good lens to use for conversions....the quality is actually outstanding!! and the lens from a Kodak instamatic 500 Schneider xenar 38mm 2.8, its suppose to be the same as the legendary 38mm robot lens, very good pictures.
