A prime lens is a type of camera lens that has a fixed focal length, meaning it cannot zoom in or out. This design typically results in better image quality, sharper focus, and wider maximum apertures compared to zoom lenses. Photographers often use prime lenses for specific purposes, such as portrait or landscape photography, where they can take advantage of the lens's unique characteristics. Because prime lenses have a set focal length, photographers must physically move closer to or farther away from their subjects to frame their shots. This encourages creativity and helps develop composition skills. Popular prime lens options include 50mm, 35mm, and 85mm lenses, each offering different perspectives and depth of field effects.
