Opting for a traditional Porro prism configuration, the Apresys Optics 8x40 M4008 Binocular delivers performance while maintaining a classic look and comfortable feel. Its moderate magnification and wide field of view minimizes the distraction of visible hand-shake common with higher-power optics, while the less conventional 40mm objective lens diameter lightens the weight and slims down the optical tubes without sacrificing low-light performance. Helping to boost its light-gathering ability are phase-correcting prism coatings and broad-band anti-reflection multi-coatings, ensuring bright and clear high-contrast images with accurate color rendition and sharp resolution.

The ergonomic design is comfortable to hold and weighted to fit solidly in the hand to reduce hand-shake and fatigue during long glassing sessions. It is made of a lightweight and impact-resistant composite chassis that is wrapped in a protective slip-resistant rubber armor. The optical tubes are nitrogen-filled and O-ring sealed to make them waterproof and resistant to fogging when moving through extreme temperature changes. A large center focusing wheel, ±4 dioptric correction, and twist-up eyecups enable precise focusing and eye relief for just about any user.
