The one thing I have yet to get when I transcended from film to digital photography.I have a Canon T100 and just got a 100mm macro lens.
Makes me wonder about using purchasing a Canon adapter that would allow me the use of some of my old FD lenses with Macro capability on an EOS style mounting my Canon EOS 1000D.
Clearly the device exists, though I assume I'd be relegated to using it exclusively on a manual basis.
