On many occasions, people may confuse the zoom lens and the zoom lens, and even their English name “zoom” is often misunderstood. Today, let us together in-depth understanding of the differences and links between the two, to avoid confusion again!

Differentiation

How it works:

1, Zoom Lens: by adjusting the optical magnification of the camera to achieve image magnification. It usually has a fixed focal length, but the magnification ratio of the image can be changed through the internal zoom mechanism.
2, Zoom Lens: by changing the focal length of the lens to achieve image enlargement or reduction. It allows the user to change the focal length by rotating the zoom ring on the lens or electronic control without changing the shooting distance, thus changing the imaging field of view and image size.

Application Scenarios:

1, Zoom Lens: more suitable for the need for a long time on the same screen shooting, observation, analysis of the scene, such as industrial testing, scientific research experiments. Its high definition, smoothness and resolution can meet the needs of long time observation camera.
2, Zoom Lens: widely used in the need to quickly change the shooting range and perspective of the scene, such as news interviews, sports events, movie production. The flexibility of the zoom lens allows the photographer to easily capture different distances and angles of the picture.

Performance Characteristics:

1、Variable Zoom Lens: Provides high clarity, smoothness and resolution at a fixed focal length, which is especially suitable for scenes requiring high image quality.
2, Zoom Lens: Although it has a zoom function, its image quality may be slightly inferior compared to fixed focal length lenses. However, the flexibility of the zoom lens makes it excellent in a variety of scenes.

Common Ground

① Adjustment Capacity：Both zoom lenses and zoom lenses allow the user to change the imaging field of view and image size by adjusting the lens or device without changing the shooting distance.

② Technological Basis：Both are designed and manufactured based on optical principles, and the imaging effect is altered by adjusting the optics inside the lens.

③ Scope Of Application： In the field of industrial inspection, both zoom lenses and zoom lenses have a wide range of applications. They both help inspectors observe and measure target objects more accurately, improving inspection efficiency and accuracy.

There are some differences in the working principle, application scenarios and performance characteristics of zoom lenses and zoom lenses. Understanding these differences helps us to better select and use them. At the same time, we should also be clear about the connection between the two, so that they can be used flexibly in practical applications. I hope this article can help you say goodbye to the confusing “Zoom” era, a more accurate understanding and use of zoom lenses and zoom lenses!
