What lens does the group take?

The focal length of a common wide-angle lens is generally 38-24 mm, and the viewing angle is 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. Wide-angle digital camera has short focal length, wide viewing angle and deep scenery, which is suitable for taking photos of large scenes, such as architecture and scenery.

Extended data:

Wide-angle lens is widely used to shoot large-scale landscape photography. Can increase the sense of spatial depth of the photo picture; The depth of field is long, which can ensure that the scene before and after the subject can be 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; The lens covers a large area and shoots a wide range of scenery; The scene shot at the same shooting distance is smaller than the image of the scene shot with the standard lens.

The defects of perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is. For most popular digital cameras on the market, the wide-angle focal length is generally between 35 and 38 mm. The real wide-angle digital camera is actually a product with a lens focal length covering a wide angle of 28 mm
