Magnification
Magnification is an important aspect of macro lenses, as it determines the size of the image on the sensor relative to the size of the subject. A magnification ratio of 1:1 means that the image on the sensor is the same size as the subject. A magnification ratio of 2:1 means that the image on the sensor is twice the size of the subject, and so on.
Macro lenses with higher magnification ratios are capable of capturing more detail, but they also have a shallower depth of field. This means that only a small portion of the image will be in focus, while the rest of the image will be blurred. Macro lenses with lower magnification ratios have a greater depth of field, but they are not capable of capturing as much detail.
The choice of magnification ratio depends on the desired effect. For example, a macro lens with a magnification ratio of 1:1 is a good choice for capturing close-up images of small objects, such as insects or flowers. A macro lens with a magnification ratio of 2:1 or greater is a good choice for capturing extreme close-up images, such as the details of an insect’s eye.
Key insights:

- Macro lenses with higher magnification ratios are capable of capturing more detail, but they also have a shallower depth of field.
- Macro lenses with lower magnification ratios have a greater depth of field, but they are not capable of capturing as much detail.
- The choice of magnification ratio depends on the desired effect.
Aperture
Aperture is an important consideration when comparing macro lenses, as it affects the depth of field of the image. Depth of field refers to the range of distances that appear sharp in an image. A shallow depth of field means that only a small portion of the image is in focus, while a greater depth of field means that a larger portion of the image is in focus.
Macro lenses with wider apertures (lower f-numbers) produce a shallower depth of field, which can be used to isolate the subject from the background. This is often desirable in macro photography, as it helps to draw attention to the subject and create a more visually appealing image. Macro lenses with narrower apertures (higher f-numbers) produce a greater depth of field, which can be used to keep both the subject and the background in focus. This is often desirable when shooting macro landscapes or other scenes where you want to capture both the subject and the surrounding environment.
The choice of aperture depends on the desired effect. For example, a macro lens with an aperture of f/2.8 can be used to create a shallow depth of field, while a macro lens with an aperture of f/8 can be used to create a greater depth of field.
Here are some examples of how aperture can affect macro photography:
- A macro image of a flower with a shallow depth of field can be used to isolate the flower from the background, creating a more visually appealing image.
- A macro image of a landscape with a greater depth of field can be used to capture both the subject and the surrounding environment, creating a more comprehensive image.
Key insights:
- Aperture is an important consideration when comparing macro lenses.
- Macro lenses with wider apertures (lower f-numbers) produce a shallower depth of field, while macro lenses with narrower apertures (higher f-numbers) produce a greater depth of field.
- The choice of aperture depends on the desired effect.
