What Are The Focusing Techniques For Fixed Focus Lenses?

The focal length of a fixed focus lens is fixed and cannot be changed. It usually has a larger aperture and higher optical quality, and is suitable for taking some high-quality pictures. So, in photography and videography, are there any tips for focusing with a fixed focus lens?

What are the focusing techniques for fixed focus lenses?

When using a fixed focus lens in photography, correct focusing techniques are essential to help you ensure the clarity and image quality of your still life works. Let’s take a look at some common focusing techniques:

Focus point selection

Fixed focus lenses require a higher degree of focus accuracy, so make sure you choose the right focus point when shooting. According to the composition of still life works, you need to focus on the key parts of the subject, such as the eyes and face, to ensure the clarity of the subject.

Use manual focus

Fixed focus lenses usually have precise manual focus functions. When shooting, you can gradually adjust the focus by turning the focus ring to ensure that the subject is clear.

Precise focus

Use auto focus

If the camera you are using supports autofocus, you can focus on the subject and let the camera automatically focus to ensure that the focus is accurate and locked on the still subject.

Focus lock

When shooting still life works, you can also use the focus lock function to first focus on the subject and then lock the focus to ensure that the focus position does not change during the shooting process.

Lock focus

Live focus adjustment

When shooting in manual focus mode, constantly check the focus position and adjust the focus ring as needed to ensure that the focus is where you want it and the subject remains sharp. You can also use the focus indicator or magnifier in the camera’s viewfinder to help you focus accurately.

Keep shooting steady

During the focusing process, keep the camera stable to avoid focusing errors caused by camera shake. You can use a tripod or stabilizer to improve shooting stability.

Keep equipment stable

Pay attention to depth of field

The depth of field of a fixed-focus lens is relatively shallow. When focusing, you should pay special attention to the focal position of the subject and the blur effect of the background to create a more layered still life work.

Pay attention to repeated checks

When taking critical shots, it is recommended to check the focus repeatedly, especially in scenes that require accurate focus, such as portraits, to ensure that the subject is clear.

Additionally, some cameras and lenses may offer a focus assist feature that helps you focus more accurately by zooming in to view subject details.
