Why does a camera magnify a distant scene?

The camera doesn't magnify the scene, but rather, the image of the scene is made by the lens onto the sensor of the digital camera or the film of the film camera, and the digital camera then enlarges the photo through the software, and the film is enlarged through the printing equipment when the photo is developed

The image of the camera is only covered by the sensor when the camera is imaging, and seems to be very small, only when we look at it through the viewfinder or the LCD screen, because we have our eyes pressed into the viewfinder, the camera has a structure similar to a telescope, or the LCD screen has been processed and enlarged by relevant software, so that it feels magnified. It is only when we look through the viewfinder or LCD screen with our eyes pressed into the viewfinder or LCD screen with a telescope-like structure or when the camera is enlarged by the relevant software that the feeling of magnification occurs

Changing the focal length of the camera only changes the size of the object in the sensor

And then the camera does magnify the object when it takes macro photography because according to the synapse imaging formula, the object becomes an inverted magnified image when the distance of the object is less than two times the focal length. This is when the image is larger than the real thing.
