A little about Macro Lenses

Macro lenses are important to photographers who tend to shoot close-ups. That’s because, although they’re quite similar to standard lenses in most ways, macro lenses are engineered to focus at much shorter distances. Most often used in nature photography, these lenses magnify small objects like insects and flowers and captures immense detail and clarity. Other applications of a macro lens are in scientific photography and product photography. You’ll find that macro lenses can also act as a standard lens.

These lenses tend to have a higher f-stop number (which allows in less light) and therefore are not always ideal in low lighting situations. For subjects that are sensitive to movement (insects and animals, for example), macro lenses with longer focal lengths can be used.
