Gerry - I confess the math of this escapes me, although I've never really sat down to crack it. Magnification is generally better than 1:1 with a "normal" lens, i.e from 40-60mm. It has to do with symmetrical vs asymmetrical lens design, pupillary magnification and such. There are probably guys on this list that can explain it! There is a brief explanation of it in the Kodak Workshop series book on Close-up photography.
