Originally posted by mi2nc What is the difference between a macro and non-macro version of a lens?
In general, a "non-macro" lens has minimal focusing distance about 10X focal length, e.g. 1 meter or 3 ft. for a 100mm lens. The maximum magnification ratio is about 1:8.
A "macro" lens can focus much closer. For most "macro" zoom lenses, the magnification ratio of 1:4 is common. Some can even do 1:2.
Note: I'm using the work "macro" with the loose usage commonly seen these days. Strictly speaking, "macro" means magnification ratio of
at least 1:2.
