Wide-angle lens is a kind of photography lens whose focal length is shorter than the standard lens, the Angle of view is larger than the standard lens, the focal length is longer than the fisheye lens, and the Angle of view is smaller than the fisheye lens. Wide Angle lens is divided into ordinary wide Angle lens and ultra wide Angle lens.
The focal length of a common wide-angle lens is generally 38-24 mm, and the Angle of view is 60-84 degrees. The ultra-wide Angle lens has a focal length of 20 to 13 mm and a viewing Angle of 94 to 118 degrees. Because the focal length of the wide-angle lens is short and the Angle of view is large, a large area of the scene can be shot in a short shooting distance range. Wide-angle digital camera lens focal length is very short, the Angle of view is wide, but the depth of field is very deep, more suitable for taking photos of large scenes, such as architecture, landscape and other subjects.
