Found something today at the local camera store I just couldn't pass up, if for no other reason that it looks like it would be fun to use.
It's a 2x teleconverter.................................
........ with a focusing helicoid built into it:
It basically acts as an extension ring when you 'run the lens out'.
I have never seen or even known about such a critter. Back in the 70's and 80's, I did have a 2x TC that the elements were mounted into a bayonet system so they could be removed, making the TC into a 32mm extension ring. But I've never seen the same concept since then. This is a close as I've ever seen.
