I think the true definition of a macro lens is that it is well corrected
for image magnification of 1:1. They also have flat fields for copy
work and likely negligable distortion as well. Nikon's lenses may all
have flat fields but I'll bet their high priced macros have even flatter
fields :-) How flat is flat?
If you were photographing a painting I think you were far enough away
that any good quality prime at apertures of f/5.6-11 would hide any
optical sins.
