macro lens

A macro lens lets you photograph something small at something close to life size. Petal structure, the compound eye of a dragonfly, the crystalline edge of a salt flake: detail that the eye skims past becomes the whole frame. This guide explains what a macro lens is, how it differs from the other lenses in your bag, what to look for when choosing one, and which subjects it suits best.

What is a macro lens?

A macro lens is built for close-up work. It focuses far nearer to the front element than an ordinary lens will, and it holds resolution at that distance instead of going soft the way a general-purpose zoom tends to. Most are prime lenses, which is part of why they render so cleanly and produce such smooth background blur.

There is no formal standard behind the word, but in practice a macro lens means two things together: a short minimum object distance, and a maximum magnification somewhere between 1:2 and 1:1. That combination is what allows a subject only a few centimetres across to

A macro lens changes the way you see the ordinary. A pincushion protea on a Cape hillside, a beetle working its way across an aloe leaf, the seed head of a restio catching late afternoon light — all of it becomes worth photographing once you can fill the frame with it. This guide covers the two subjects most South African photographers reach for first, flowers and insects, and sets out what to look for when you buy your first macro lens.

What makes macro lens photography so rewarding?

Before getting into technique, it helps to understand what actually separates a macro lens from the rest of your kit. Once those differences are clear, the shooting decisions further down this article start to make a lot more sense.

What sets a macro lens apart

Two specifications define a macro lens: a high maximum magnification and a short minimum focusing distance. Together they let you work far closer to your subject than any standard lens allows, so a flower head that would sit lost in the middle of a
