What is a super wide-angle lens?

A lens with a particularly wide angle of view

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer distance and smaller viewing angle than standard lens.

Lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses. 135 camera's common wide-angle lens has a focal length of 38-24 mm and a viewing angle of 60-84 degrees. The ultra wide-angle lens has a focal length of 20- 13mm and a viewing angle of 94- 1 18 degrees. Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance. Therefore, it is widely used to shoot large-scale landscape photography.

Extended data:

In photography creation, shooting with a wide-angle lens can achieve the following effects:

1 can increase the sense of spatial depth of photographic images.

2, the depth of field is long, which can ensure that the scenes before and after the subject are clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool cameras) use ordinary wide-angle lenses of 38-35 mm

3. Large lens coverage and wide shooting range.
