Let's Get Started
Just picked up a new macro lens? This guide will help you get started. Macro photography can feel challenging at first, especially if you are used to more traditional styles of shooting. One of the biggest adjustments is focus. In macro photography, autofocus is often unreliable, so manual focus becomes your most valuable tool.
That might sound intimidating, but it is easier than it seems. With the right approach, you will be capturing sharp macro images in no time.
1. Understanding the Basics
One of the first things to understand is that macro photography comes with a “built-in” challenge: extremely shallow depth of field.
In genres like portrait or wildlife photography, a shallow depth of field is often desirable. In macro photography, it becomes a limitation. When you start shooting with a macro lens, you will quickly notice that only a very small portion of your subject is in focus. Even at smaller apertures such as f/16, the area in focus can be just a thin slice.
This happens because of magnification. As you move closer to your subject and increase magnification, depth of field decreases dramatically. In practical terms, the closer and smaller your subject is, the harder it becomes to fully keep it in focus.
2. Get Your Settings Right
If you are coming from other types of photography, your usual aperture choices may not achieve your desired results.
In macro photography, it is best to avoid very wide apertures, as they result in extremely shallow depth of field. At the same time, very small apertures can reduce image quality due to diffraction.
Diffraction occurs when light passes through a very small aperture and begins to spread out, reducing overall sharpness. While this does increase depth of field, it often results in softer images.
Most lenses perform best somewhere in the middle of their aperture range. For example, the Laowa 90mm f/2.8 is often sharpest around f/11, while the OM System 60mm f/2.8 performs best closer to f/7. These values will vary depending on your lens, so it is worth checking reliable tests or reviews.
As a general rule, try to stay near your lens’s sharpest aperture. For very small subjects, you may need to stop down further and accept a slight loss in sharpness to gain more depth of field.
3. Macro Focusing Technique
This simple but effective focusing technique can make a huge difference in your results.
Start by turning off autofocus. While modern autofocus systems are very advanced, they struggle with the tiny shifts in distance that occur in macro photography. Manual focus gives you far more control.
Set your focus by turning the focus ring on your lens. Do not worry about being perfectly accurate at this stage. Once you have set a focus distance that magnifies your subject to your liking, stop adjusting the lens.
Now comes the key step. Instead of refocusing, gently move your camera back and forth toward your subject. As you do this, you will see the focus plane move across your subject in the viewfinder.
When the most important part of your subject becomes sharp, take the shot.
4. For better stability
- Hold your camera with both hands
- Tuck your arms into your body
- Use slow movements
If you move too far, simply shift back slightly and try again. This technique takes a bit of practice, but it is one of the most reliable ways to achieve sharp focus in macro photography.
