What does mechanical zoom mean?

Mechanical zoom refers to the process of using a mechanical mechanism to adjust the focal length of an optical lens to enlarge or reduce the image. Unlike digital zoom, mechanical zoom changes the focal length by physically moving the lens, so it is more stable and reliable, and the image quality is clearer.

Mechanical zoom is widely used in photography, videography, surveillance and other fields. Through mechanical zoom, the camera can achieve long-distance shooting, and the shooting objects are more diverse. In the field of surveillance, mechanical zoom can also help surveillance lenses adapt to shooting needs in different environments.

Compared with digital zoom, mechanical zoom has a higher image quality guarantee. After adjusting the focal length to the appropriate position, the camera does not need to zoom in, so there will be no loss of image quality. In addition, the mechanical zoom knob can read the user's instructions more accurately and adjust the focus more naturally and smoothly.
