What Does Prime Lens Mean?

As a Lens Manufacturing Company, share it with you.

A fixed focal length lens specifically refers to a lens with only one fixed focal length, only one focal length, or only one field of view. The fixed focus lens has no zoom function. The design of a fixed focus lens is much simpler than that of a zoom lens, but the general zoom lens will affect the imaging during the zooming process. The biggest advantage of a fixed focus lens over a zoom machine is that the focusing speed is fast and the image quality is stable. Many digital cameras with fixed-focus lenses have clear and stable images of moving objects, very accurate focus, delicate images, very slight graininess, and relatively accurate metering.

Fixed Focal Length Lenses

Lens features:

The design of a fixed focus lens is much simpler than that of a zoom lens, but the general zoom lens will affect the imaging during the zooming process. The biggest advantage of a fixed focus lens compared to a zoom machine is that the focusing speed is fast and the image quality is stable. Especially suitable for large-scale landscape photography, large-scale group photo taking.

Lens advantages:

The benefits of fixed focal length lenses are mainly reflected in the use of short focal lengths:

1. The fixed-focus wide-angle or standard lens is generally larger than the zoom lens covering the corresponding focal length. The apertures of general fixed-focus wide-angle and medium-focus lenses are above 2.8, and the amount of light is large, which is convenient for shooting in low-light conditions.

2. The fixed-focus wide-angle lens generally has a shorter focusing distance than the zoom lens covering the corresponding focal length. The small closest focusing distance has many benefits, especially for wide-angle lenses. A short focusing distance means that you can get very close to the subject and get a large image. And in conjunction with their large aperture, it can achieve a wide-angle background blur effect that is not easy to achieve with a zoom wide-angle lens.

3. Fixed-focus wide-angle lenses are generally smaller and lighter than zoom lenses covering the corresponding focal length. This can make your camera less eye-catching and easy to capture.

4. The wide-angle fixed focus lens generally has better imaging than the wide-angle range of the zoom lens. This is determined by the design of the lens. Since the zoom lens has to consider all focal lengths to have relatively good imaging, it is necessary to sacrifice local interests to allow the overall A relatively good performance. But the prime lens does not need to consider these.
