I got one of these, and its pretty slick. First it is a 2X converter, with I
think several elements (7) and so perhaps better corrected than the cheap
ones. At the normal 2X setting, it allows larger subject magnification, as
the minimum focusing distance of the mounted lens doesn't change. Then it
has a focusing helicoid, so it will add extension to the mounted lens,
enabling closer than the otherwise minimum focus. With a 50mm lens you can
get up to 1:2 ratio (or is it 1:1? I don't have mine in front of me). For
the price on e*ay you might look for one instead of a cheapo 2X and
extension tubes...
