No, it's the modification I've published here around two years ago.
a very simple modiicaion inside the lens to add a "reed relay" inside it (just by removing the lens backplate and adding the reed relay inside, nothing visible outside, and no functional changes).
You leave the lens in e-zoom mode inside the housing, and you then set macro mode by a moveable magnet outside the house. I can re-publish the pictures i there is interest.
