It I read the following posting correctly, it appears that
not all macro lenses are flat-field
http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=000Nrf
and - of course - not all flat-field lenses (e.g. enlarger
lenses) are macros.
No, the better performance results from the design
optimized for 1:1 magnification, instead of 1:20 for non-
macro lenses. Some macros don't work well at low
magnifications (infinity focus) for the same reason.
Don't confuse macro lenses with standard lenses that have a
"macro" setting. This isn't real macro (at 1:1), but
usually just close-up (around 1:4 to 1:2).
