National Geographic 8x40 BAK-4 Porro Prism Binocular

National Geographic 8x40 BAK-4 Porro Prism Binocular

The National Geographic 8x40 BAK-4 Porro Prism Binocular is set up for birdwatchers, with BAK-4 prisms and fully multi-coated optics. It is equally at home on a mangrove boardwalk or a mountain trail.

Features and Benefits

The upgrade here is the glass. BAK-4 porro prisms and fully multi-coated optics help more light reach your eye, which shows in colour and contrast when a bird sits in shade.

Additionally, 8x magnification paired with 40 mm objectives keeps the image steady and bright. The field of view is 110 m at 1,000 m (331 ft at 1,000 yd), wide enough to track a bird as it flies between perches.

Moreover, a central focusing wheel and diopter adjustment give you a sharp image in both eyes. The rubber-coated body adds grip, and the pair ships with a case, strap, lens covers and a cleaning cloth.

Product-Specific Use Cases

Bring the National Geographic 8x40 BAK-4 Porro Prism Binocular to the Al Zorah or Umm Al Quwain mangroves at first light, when herons and kingfishers are most active. It works just as well on a Hajar Mountains hike or watching the dunes from a desert camp.
