A prime lens is a type of camera lens with a fixed focal length, meaning it does not zoom in or out. This design allows for simpler construction, resulting in better image quality, sharper focus, and often a wider maximum aperture compared to zoom lenses. Common focal lengths for prime lenses include 35mm, 50mm, and 85mm, each offering unique perspectives for photography. Photographers often prefer prime lenses for their ability to produce high-quality images with beautiful background blur, known as bokeh. Additionally, using a prime lens encourages photographers to move around and find the best composition, enhancing their creativity and skills.
