Another way is to mount a double 49mm ring on the filter thread of *two*
lenses. You get a double lens very effective for cheap macro. The longer
lens on the camera. With two 50 mm you get a 25mm in macro 1:1 position
(absolutely symmetrical if you use two companion lenses). The focus plane
comes very near the outer element, but this is the only drawback. You can
focus with the camera-mounted lens, of course. The other focus ring give
you a sort of retractile hood. No double cable is required. Say you get a
very sophisticated adjunctive lens.
