The rangefinder one is supposed to be identical, and is very good (relative to other normals and macro lenses of the period) at any distance. But even though it already started good, the 55mm got even better on every update (well, the floating element does not coexist too well with extension rings or bellows, so there are applications where the excellent f/2.8 loses some of its excellence). If it is not for collection purposes or to match a equally old camera and use a consistent period piece, I'd go with a cheaper, later one...
