How do you use manual focus for macro photography?

1 What is manual focus and why use it?

Manual focus is a mode that lets you adjust the focus of your lens by turning a ring or a dial, instead of relying on the camera's autofocus system. While autofocus is convenient and fast for most situations, it can struggle in macro photography for several reasons. For example, autofocus may not lock on the subject accurately, or it may switch focus to the background or foreground. Also, autofocus may not allow you to fine-tune the focus exactly where you want it, especially when you are working with very shallow depth of field. Manual focus, on the other hand, gives you full control and precision over the focus point and the depth of field, allowing you to achieve sharper and more creative results.

2 How to set up your camera for manual focus

To use manual focus for macro photography, you need to set up your camera and lens accordingly. First, you need to switch your lens to manual focus mode, either by using a switch on the lens barrel or by changing a setting in the camera menu. Next, you need to set your camera to a mode that allows you to adjust the aperture and shutter speed manually or semi-automatically, such as aperture priority, shutter priority, or manual mode. This way, you can control the depth of field and the exposure of your macro shots. Finally, you need to enable some features that can help you with manual focusing, such as live view, focus peaking, or magnification.

3 How to use live view for manual focus

Live view is a feature that lets you see the image on your camera's LCD screen or an external monitor, instead of using the viewfinder. Live view can be very helpful for manual focus, as it allows you to see the subject more clearly and zoom in on a specific area to check the focus. To use live view for manual focus, you need to activate it by pressing a button on your camera, usually labeled with a camera icon or LV. Then, you need to frame your subject and turn the focus ring until you see the subject in focus. You can also use the zoom buttons or the touch screen to magnify the image and fine-tune the focus.

4 How to use focus peaking for manual focus

Focus peaking is a feature that highlights the edges of the in-focus areas with a colored overlay, making it easier to see where the focus is. Focus peaking can be used in conjunction with live view or the viewfinder, depending on your camera model. To use focus peaking for manual focus, you need to enable it in your camera's settings, usually under the display or focus options. Then, you need to choose a color for the overlay, such as red, green, or yellow. After that, you can turn the focus ring and see the overlay appear on the in-focus areas. You can also adjust the sensitivity or level of the overlay, depending on your preference.

5 How to use magnification for manual focus

Magnification is a feature that lets you enlarge a portion of the image on your camera's LCD screen or viewfinder, making it easier to see the details and the focus. Magnification can be used in conjunction with live view or the viewfinder, depending on your camera model. To use magnification for manual focus, you need to activate it by pressing a button on your camera, usually labeled with a magnifying glass icon or MF. Then, you need to move the cursor or the touch screen to select the area you want to magnify. After that, you can turn the focus ring and see the image enlarged and focused.

6 Tips and tricks for manual focus

Manual focus for macro photography can be rewarding and fun, but it takes some practice and patience to master. To avoid camera shake and maintain the focus point, use a tripod or a stabilizer. Additionally, use a remote shutter release or a self-timer to avoid touching the camera and causing vibrations. Setting a small aperture (high f-number) will increase the depth of field and the sharpness of your macro shots. You can also use a focus rail or a slider to move your camera back and forth and adjust the focus without changing the composition. Lastly, manual focus bracketing or stacking can be used to take multiple shots with different focus points which can then be combined in post-processing for maximum sharpness.
