A prime lens is a lens with a fixed focal length, meaning it cannot zoom in or out. This allows for a simpler and more compact lens design, often resulting in better image quality.

Prime lenses typically offer better image quality due to their simpler design, faster aperture for low-light photography and shallow depth of field control, and are often smaller and lighter than zoom lenses.

Prime lenses have a fixed focal length, while zoom lenses have a variable focal length. Prime lenses are typically faster than zoom lenses, meaning they have a wider maximum aperture. Prime lenses are often smaller and lighter than zoom lenses.

The most common focal length for a prime lens is 50mm, which is considered a normal lens on a full-frame camera. It provides a natural perspective similar to the human eye.

A wide-angle prime lens is a prime lens with a focal length less than 50mm. These lenses are used for capturing wide scenes, such as landscapes or group photos.

A telephoto prime lens is a prime lens with a focal length greater than 50mm. These lenses are used for capturing distant subjects, such as wildlife or sports.

Prime lenses offer better image quality, faster aperture for shallow depth of field control, and are often smaller and lighter than zoom lenses, making them ideal for portrait photography.

Prime lenses offer faster aperture for capturing candid moments, are smaller and lighter for easy carrying, and provide better image quality for capturing details, making them suitable for street photography.

Wide-angle prime lenses offer a wider field of view, allowing photographers to capture vast landscapes in a single shot.

Telephoto prime lenses offer a longer focal length for capturing distant subjects, faster aperture for capturing fast-moving subjects, and better image quality for capturing details, making them ideal for wildlife photography.

Telephoto prime lenses offer a longer focal length for capturing distant subjects, faster aperture for capturing fast-moving subjects, and better image quality for capturing details, making them suitable for sports photography.

Macro prime lenses offer a longer focal length for capturing small subjects, faster aperture for capturing low-light scenes, and better image quality for capturing details, making them ideal for macro photography.

Prime lenses with faster aperture are preferred for astrophotography as they allow more light to enter the lens, resulting in brighter and sharper images of stars and galaxies.

Prime lenses have less versatility compared to zoom lenses, require photographers to carry multiple lenses for different focal lengths, and are often more expensive than zoom lenses.

Prime lenses should be used when photographers need the best possible image quality, a faster aperture for low-light photography, or a smaller and lighter lens.
