National Geographic 8x40 Porro Prism Binocular

The National Geographic 8x40 Porro Prism Binocular is a classic full-size pair for steady, bright viewing on the trail or at camp. Its wide field makes it easy to follow birds working along a wadi bed or wildlife moving across open ground.

Features and Benefits

The 8x magnification with 40 mm objectives balances reach with a bright, stable image. Lenses and prisms are made from BK-7 optical glass. The porro layout gives classic wide-set barrels.

Additionally, the field of view measures 110 m at 1,000 m (330 ft at 1,000 yd). Scanning a hillside is quick. A central focus wheel and a plus or minus 2 diopter setting fine tune each eye.

Furthermore, eye relief is 15 mm. The interpupillary range of 56 to 72 mm (2.2 to 2.8 in) suits most adults. The minimum focus distance is 7 m (23 ft), and the rubber coating improves grip.

Product-Specific Use Cases

Use the National Geographic 8x40 Porro Prism Binocular on Hatta Dam walks, Wadi Shawka scrambles or around the campfire at a desert camp. One note for UAE summers. The rated operating range tops out at 40°C (104°F), so keep it out of a parked car in July.
