I know what Macro lens means, but what I am really saying is what makes a lens a "macro" lens? I thought a macro lens has the maginfication of 1:1 but almost every sigma lens is considered a macro lens. Sigma's 28-200mm lens is labeled as a macro lens but the magnification of the lens is 1:3.8.

So at what point of the magnification is it that it is no a macro lens?
