Toting up to elaborate that this is possible in porro prism type binoculars only because it folds the optical path which results in having the lower physical length than the actual focal length.
Magnification – this binocular brings into being a magnification from 10x to 22x. This describes that while using the binocular the image is multiplied 10 times to 22 times and anywhere in between them. This model provides a higher magnification which is more apt for tripod than hand held as generally in models which exceed 10x the magnification is prone to be lost in hand shake. This proves great for out door activity and when accompanied with a tripod.

In this case the magnification and the field of view are inversely related as the higher the magnification the lesser will be the field of view.

Relative brightness – judge against it! This is why the Relative brightness index (RBI) is stated by the manufacturers. Well!

The higher the value the better it is chosen.
