Prime Lens gives a fixed focal length. If you have a 35mm Prime Lens, the only focal length you will ever use is 35mm. The Prime Lens is often used in situations where the subject is relatively stationary and you, the photographer, can move around.

These categories include Wedding, Portrait, Landscape, and Streetscape photography. Prime lenses offer various advantages to zoom-capable lenses, including a lower overall weight, superior performance in low-light and nighttime photography, and typically higher image quality. Prime lenses have some major drawbacks, along with the fact that you cannot zoom in even if you want to, the fact that you need to carry many lenses in most situations, and the possibility that you will miss a shot when switching lenses.
