Is the wide angle 0.5 or 0.7 better?

The choice of wide angle depends on what you choose to shoot.

If you want to shoot everything in the line of sight, it is recommended to use a wide angle, such as 0.7. If you want to shoot something close and single, you can choose a small angle, such as 0.5.

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

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

2. Under wide angle, the field of view of most digital cameras is very narrow. When shooting in a narrow room, the coverage of the lens will not be enough, and there will be many dead ends in the picture. If you want to shoot comprehensively, you can only rely on the lens itself to constantly focus left and right to make up for the scenes that can't be shot by a single picture. But we also know that such telephoto shooting will definitely affect the shooting effect and stability of the picture. Therefore, it is very necessary to equip a wide-angle lens when shooting in a narrow indoor space with DV.

3. When choosing a wide-angle lens, you will find that the lens is generally marked with x0.7, x0.6, x0.5, 0.45, 0.43, etc. These data represent the magnification of the lens. Generally, if the lens is marked with positive numbers x 1, x2, x3, the magnification of the original lens will be increased, for example, the magnification of the original lens is 65438+. If the decimal points such as x0.7 and x0.6 are marked, the magnification of the original lens will be reduced backwards, which means that the viewing angle will increase, so the smaller the number, the wider the angle will be. Personally, I suggest that users generally choose x0.7, x0.6 and x0.5, and below 0.45, it is close to the "fisheye" effect. The original arc deformation of the picture is very exaggerated, which is suitable for special shooting needs and not suitable for general shooting.

4. 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.
