Over a half century ago, Nikon made their post-WW2 claim to fame by developing lenses able to accurately & evenly enlarge & project micro-fiche stored film images. They named their line of lenses "Micro", and have continued with that nomenclature long after micro-fiche storage was superseded by magnetic, and now digital record storage.
Thanks Nikonian......had to be history and not arbitrary....
actually I really never understood the origin of macro...my physics and optical education early on did not see the need for macro and or micro....why both?
