Suppose it is inserted on a 4x8 camera, which means that the large lens of the camera is 2 mm and its zoom power is 2 times.
ROOF or Porro
In general, binoculars are divided into two categories, the first of which is ROOF and the second type of Porro. ROOF cameras look more elongated and are more expensive because of the more sophisticated process, but Rorro cameras look wider and usually "cheaper.

Lenses and camera charters
In high quality cameras, coatings on lenses as well as the camera charter are used, which is the main purpose of preventing light reflection and clarifying the image.

To determine which charter used in your camera, just look at the camera (light).
