What is suitable for prime lens? Generally speaking, 20 mm prime lens, 24 mm prime lens and 28 mm prime lens can be used when taking scenery photos. A 35 mm prime lens can be used when taking humanistic photos. One step back can include more scenes and take pictures of the overall environment. It can further filter out needless backgrounds and highlight the main body. The photographer can use a 50 mm prime lens when taking portraits. When shooting scenery with few scenes, an 85 mm prime lens can be used. For long-distance portrait shooting, the photographer can use 135 mm prime lens. For ecological photography, sports photography, etc., the photographer can use a 200 mm prime lens.

The prime lens has a larger aperture. The large aperture can control the depth of field of the photo, through which the photographer can guide the audience's attention to the most important things in the photo. In portrait photography, it is very important to separate the model from the background. If you notice the advertisement in the magazine, you can see many of these effects. The additional benefit of large aperture is that it can reduce photo noise. Most prime lenses have depth-of-field scales. It can read the current depth-of-field range and focus distance. It is very useful for shooting that requires strict control of depth of field. Under the same focal length, the prime lens is sharper and the focusing distance is shorter.

In short, a prime lens means that the focal length of the lens is fixed. When you select a shooting point and angle, the composition picture is fixed and cannot be changed. The zoom lens, on the other hand, has a variable focal length. When you select a shooting point and angle, you can change the size of the composition picture by adjusting the focal length. It can realize the choice of different pictures and realize different expression intentions.

The prime lens can only change the framing range by changing the distance between the camera and the shooting subject. That is to say, "shooting different scenery can only be done by walking". Prime lenses provide only one angle of view. This is a good practice opportunity. Through a lot of practice, photographers can master the advantages and limitations of each focal length. Zoom lenses will make photographers lazy and unwilling to move themselves to get better shooting positions.

Finally, the question of what the prime lens is suitable for shooting is summarized: the design of the prime lens is much simpler than that of the zoom lens. However, the general zoom lens will affect the imaging during zoom. Compared with zoom lens, prime lens has the greatest advantages of fast focusing speed and stable imaging quality. It is especially suitable for large-scale scenery photography and large-scale group photo photography.
