Kiinteäpolttoväliobjektiivit
Kiinteäpolttoväliobjektiivit, often referred to as prime lenses in English, are a fundamental type of photographic lens. Unlike zoom lenses, which offer a variable focal length, prime lenses have a single, fixed focal length. This means their magnification and field of view remain constant, and the photographer must physically move to adjust the framing of the image.
The fixed focal length design often allows for simpler construction compared to zoom lenses. This simplicity
Furthermore, prime lenses are often sharper and exhibit fewer optical aberrations such as distortion and chromatic
