What is a fixed photographic lens?

The fixed photographic lens is an irreplaceable lens on the camera, also known as the original lens. Corresponding to this is the zoom lens, which can be adjusted at different focal lengths. Fixed photographic lens can not adjust the focal length, but the optical quality is higher and the maximum aperture is larger. Because no mechanical structure is needed to adjust the focal length, the fixed photographic lens can be designed to be smaller and lighter, so it is widely used in cameras of photographers and professional photographers.

The fixed photographic lens is also extensible. They can extend their functions by using filters, such as aurora filters and polarization filters. Filters can be used to adjust color balance, reduce luster and improve contrast, thus creating more unique photographic effects. In addition, some fixed photographic lenses can also use additional lenses or adapters to expand their focal length and field of view. These additional devices can make the fixed photographic lens more flexible and meet different shooting needs.

In a word, the fixed photographic lens is a kind of high-quality, portable and extensible photographic equipment, which is suitable for various shooting scenes and needs.
