Is the fixed focus lens better or the zoom lens?

Whether a fixed-focus lens is better or a zoom lens has its own advantages and disadvantages, depending on your photography needs and preferences.

In fact, choosing different lenses will bring us different photographic feelings, and the sense of picture is also very different. But most photographers still can't understand their own photography needs and have no concept of the lens. Let me tell you the difference between a fixed-focus lens and a zoom lens to help you choose the lens that suits you.

The difference between the two lenses 1, fixed focus lens

Refers to a lens with a fixed focal length and no zoom function.

① The fixed-focus lens has simple design, fast focusing speed and stable imaging quality. In other words, the fixed-focus lens performs better than the zoom lens in image quality (but not every fixed-focus lens has such characteristics). ② General fixed-focus lenses have the characteristics of large aperture, such as F2.0, F 1.8, F 1.4, F 1.2, etc. A large aperture can control the depth of field of a photo, which can guide the audience's attention to the most important thing in the photo. Therefore, the people and still life that the fixed-focus lens wants to express are more vivid and prominent than the zoom lens.

(3) but the disadvantage of fixed-focus lens is trouble. If you want to take different photos, you can only go by yourself, and you can only change the viewing range by changing the distance between the camera and the subject. For example, if you want to take a panoramic view of the building, you have to run thousands of meters away from the building to take a panoramic view. How far you run depends on the size of the building. )

④ The fixed-focus lens has almost no distortion in the imaging effect, which is better than the zoom lens, and the picture taken is relatively clear.

The common focal lengths of fixed-focus lenses are 24mm, 35mm, 50mm, 85mm and so on. Some high-end photographers will choose fixed-focus lenses with telephoto segments, such as 200mm, 400mm, 600mm and 800mm. For example, a 24 mm fixed-focus lens with a fixed focal length of 24 mm.

2. Zoom lens

Refers to a lens whose focal length can be changed within a certain range, that is, the focal length can be changed.

① The zoom lens can change the shooting range by changing the focal length without changing the shooting distance. It is relatively convenient for zoom lens to be used as several fixed-focus lenses. The biggest advantage of using a zoom lens when shooting is that we can directly shoot different pictures supported by the focal length of the lens without walking around.

② The disadvantage of zoom lens is that the picture is easily deformed, and it will be distorted as long as there is a wide-angle zoom lens. At the same time, the picture taken with the zoom lens always feels blurred. Simply put, it's mushy.

③ Generally speaking, the aperture of zoom lens is generally smaller than that of fixed-focus lens, and the imaging quality is not as high as that of fixed-focus lens in the focal section.

Common zoom lenses are 1 1-24mm, 14-24mm, 16-35mm and so on. For example, a zoom lens of 1 1-24mm can change the focal length between 1 1 and 24mm at will.
