Why is there only one camera working on the iphone7P? I can still zoom in and out by covering the other head. It has nothing to do with it.

This is because the iphone 7P uses asymmetric wide-angle and telephoto lenses, and the left and right cameras use different viewing angles, which makes the two cameras take different views. The close shot is wide-angle on the left and telephoto on the right.

The specific explanation is as follows:

Only one wide-angle lens works during normal operation. Only by doubling the magnification can the two of them work together. But sometimes, for example, in a dark environment, in order to ensure the amount of light, only one wide-angle lens will work.

When blocking the wide-angle lens, the screen is black and cannot be shot normally. When the telephoto lens is blocked, he will calculate and change the shooting parameters of 7P to achieve the best shooting state.

Extended data:

The iPhone 7 Plus has a screen size of 5.5 inches and a dual camera with12 megapixels. The blur effect is natural, the brightness is increased by 25%, and the color is better.

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

A long focal length lens refers to a photographic lens whose focal length is longer than that of a standard lens. It has natural advantages in long-distance shooting of scenic figures, tourism photography and portrait photography.
