You need to be careful which Vivitar 2X multiplier you buy. The one with the
macro capability is a large heavy rascal at 10.4 ounces. I have another
Vivitar 2X MC without the macro feature that only weighs 4.5 ounces. As a
comparison, the Zuiko 2XA weighs 8.5 ounces. I have never compared test
pictures with these three so will do that and let you know what I see. /jim

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...
