Binocular National Geographic 10x50 Porro

Технички спецификации

PRODUCT DESCRIPTION These elegant Porro-prism binoculars have excellent optical characteristics. The green fully coated optics guarantee a decisively higher light transmission through the glass, thus increasing color fidelity and contrast. Diopter compensation is standard with these models. This makes these binoculars suitable for beginner birders or nature observers. Even on windy days, due to the 10-fold magnification, a stable image is provided. The 50 mm objective lenses gather enough brightness for observation even in twilight conditions. A carrying pouch and neck strap are included. For longer observations, a tripod-adapter thread is integrated.
