How wide is the viewing angle and aperture of GoPro lens?

You can't adjust the wide-angle width of gopro. The wide angle is fixed and cannot be adjusted. There is no data to check the aperture parameters, which need to be determined according to the size of the site and the lighting conditions when shooting.

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens. Wide-angle lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses.

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.

Extended data:

The basic characteristics of a wide-angle lens are its large viewing angle and wide field of vision. The range of scenery observed from a certain viewpoint is much larger than that seen by human eyes at the same viewpoint; The depth of field is long, which can show a fairly clear range; It can emphasize the perspective effect of the picture, be good at exaggerating the foreground and express the sense of distance of the scene, which is conducive to enhancing the appeal of the picture.

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 scene image shot with standard lens in the picture; 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.
