Q: What is the difference between a fixed lens and a motorized zoom lens?
A: Fixed Lens (Prime Lens):
A fixed lens, also known as a prime lens, has a fixed focal length. This means that the lens has a single, unchangeable field of view.
Prime lenses are often known for their optical quality and can have wider apertures compared to zoom lenses at the same focal length. This wide aperture allows for better low-light performance and depth of field control.
Motorized Zoom Lens:
A motorized zoom lens, as the name suggests, has a zoom mechanism that allows you to change the focal length and, consequently, the field of view.
Motorized zoom lenses are versatile because they offer variable focal lengths, allowing you to zoom in for close-ups or zoom out for wider shots without physically changing lenses.
They are commonly used in applications where the camera may need to adjust its field of view remotely or automatically, such as in surveillance systems, video conferencing setups, or certain types of filmmaking.
In summary, the key distinction is that a fixed lens has a single, unchangeable focal length, while a motorized zoom lens has the capability to vary its focal length. The choice between the two depends on the specific needs of the photographer or videographer and the requirements of the given situation or application.
For example as below photo:
Fix lens camera is the first picture, it’s a fixed vision, and can’t zoom in/out.
Varifocal camera is the second picture, it’s a 10X motorized lens and can zoom in/out in long distances.
