Thanks for the quick reply Jostein. It appears that "male to male ring" will find what I'm looking for on that infernal auction site, but in the process I'm afraid that Google's profile of me just changed in a rather inaccurate way. You may also add the word "macro" or "coupling" to your search.
I just ordered a 58 to 49mm version so I can try reversing 50mm or 55mm Takumars on the front of my F100mm macro. I wonder what the Sigma EX 28mm f1.8 would do reversed on the front of that F100? It has a 77mm filter size. Hmmmm.
