A high-quality camera typically uses a prime lens or a zoom lens with high-quality optical elements. Prime lenses are known for their sharpness, clarity, and low distortion due to their simpler optical design with a fixed focal length. Zoom lenses, on the other hand, offer versatility with the ability to zoom in and out, but may sacrifice some image quality for convenience. High-quality cameras also often use lenses with wide apertures, such as f/1.4 or f/2.8, which allow for more light to enter the camera and provide better low-light performance and shallow depth of field. Additionally, high-quality lenses are constructed with advanced coatings and materials to reduce aberrations, improve contrast, and enhance overall image quality.
