Wow, so much response so fast.
Thanks to all of you!
Unfortunately, there are no pics. I did that over five months because I moved house, and my little daughter was born.
I did not have the patience in that long period of time to take photos of the process.
My pictures would not help much because it was no clean process at all.
I started to do it with a M39-M adapter plus a M-NEX adapter, and took away the rear base of the lens to achieve infinity. Not succeeding, I used a different mount (cut from a M42-Nex adapter). This means, the entire process was not perfect. At some time I thought I could not succeed. I would have done it different if I had the knowledge before.
It focuses to infinity. Built in means I always have close focus capability, too, thanks to the Macro double helix.
Hmmm, I did not think about that during the conversion process. The easy part with this lens is that there are two "lens blocks" which screw into a metal tube. The aperture sits in the middle.
That makes the elements easy to disassemble, easy to clean, and solid. I'm not saying it is impossible, but the solid tube may hinder exchanging the entire mechanism with that of a donor lens.
I will write down what essentially has to be done, but not today any more.
And you are right: not to hijack this thread, I'll open a new one.
I'll do it tomorrow or within the next week.
