National Geographic 7x50 Porro Prism Low-Light Binocular

National Geographic 7x50 Porro Prism Low-Light Binocular

The National Geographic 7x50 Porro Prism Low-Light Binocular is specified for the hour either side of sunset. With a twilight factor of 18.7, it keeps detail visible long after the dunes lose their colour.

Features and Benefits

A relative brightness of 51 comes from pairing 50 mm (2 in) objectives with a modest 7x magnification. In practice that means a bright, easy view at dawn, at dusk and under a clear night sky.

Additionally, the fully coated optics carry a green coating, and the BK-7 prisms sit in a metal body with rubber and metal armouring. Dust caps for both the objectives and the eyepieces are individually removable, so sand stays off the glass between sessions.

Furthermore, focusing is quick: the drive covers the full focal range in 1.25 turns. The interpupillary distance adjusts from 58.5 to 71.3 mm (2.3 to 2.8 in), and diopter compensation balances your eyes.

Product-Specific Use Cases

Set up a camp chair in Liwa or Al Quaa and scan star clusters and the Moon by hand. National Geographic 7x50 Porro Prism Low-Light Binocular is also a good companion for early-morning wildlife walks, when gazelle and birds are active before the heat builds.
