People divide binoculars into 2 kinds. The division is done according to the method of their construction. It depends on the type of prism. In compact zooms lenses and oculars are situated on the same optical axis that gives to a zoom its small sizes.
When you take a binocular with Porro prism you can find that the visual axis of the lens is bigger then the visual axis of the ocular. It makes a zooms bigger. But the point is that you receive a better picture.
With the assistance of zoom factor you can look at the observation objects farther or closer. For example, the thing that is situated in 100 meters from you will be seen as from 10 meters through a 10-fold zoom. If a zoom factor is great enough your perception of the objects will be definitely well. But when a zoom factor is great the convenience of observation is low. It means that the image begins to shake even of your breath. So you should supply a stationary position to this kind of zooms.
