Macro, strickly speaking is 1-1, but over the years the boundry has become somewhat blurred.
Many of the low end lenses and the majority of compacts come complete with a "macro" setting which give a 1-2 ratio.
Nowadays due to many people in the digital age being brought up with the lower end lenses and compacts.
Close-ups now appear in the forums and also the digital photo mags and are termed as macro. I guess that is what's called progress.
I often take photos that are approx 2-1 such as this image, of a fly or this spider, But I now go with the "flow" and accept close-ups as macro.
I guess when you have 18mp cameras a crop is as good as a "true macro"
