Zoom
The main advantage of a zoom model like Kenko 10-30×21 MC HG binoculars is that, as in this case, you will be able to turn the magnification power from a minimum of 10x to a maximum of 30x. In practice, the zoom function allows you to firstly spot your target from afar with the minimum magnification power and then to zoom in it as much as you need to observe all its details.
Zoom type binoculars are therefore particularly suitable for hiking, sport games or theater shows, and outdoor events of every kind.

Porro prism
Named after the Italian optician who patented this system, porro prism binoculars make use of a double prism Z-shaped configuration to show the image. By separating the two lenses, the binoculars’ size is increased but, on the other side, porro binoculars have the additional advantage of folding the optical path so that the physical length of the binoculars is less than the focal length of the object. Simply speaking, it gives a better depth perception.

Multi-coating
Glass-to-air lenses surfaces are multi-coated to reduce light loss and achieve a higher light transmittance.

Strap hole
Kenko HG binoculars’ design provides for a strap hole on both sides of the binoculars body. Such a small and yet useful detail will make it possible to comfortably bring these binoculars with you everywhere by simply attaching to them the strap included or your favorite neck strap.
