Pentax – 8×25 U-Series UP WP Compact Binoculars

Use and Handling

Dual-axis synchronized eyepiece adjustment ensures symmetrical placement when changing interpupillary distances

Construction Details

Lightweight fiberglass reinforced polycarbonate housing

• Pentax’s highly portable and functional 8×25 U-Series UP WP Compact Binoculars employs an innovative unibody design that locks the objective lenses into the body with the eyepieces set on a synchronized dual-axis mechanism that ensures they stay symmetrical in relation to the center axis of the optic when adjusting the interpupillary distance. The 25mm objective lenses are fully multicoated to reduce reflection and maximize light transmission to produce the brightest images possible. Aspherical lens elements virtually eliminate distortion, especially around the edges, and corrects for lens astigmatism which can prevent sharp focusing.
• Designed for easy carrying and stowing, the binocular features a lightweight fiberglass reinforced polycarbonate housing that is corrosion and impact resistant. The housing material is also temperature-resistant allowing for its use in extreme climates while reducing expansion and contraction wide temperature variations can cause, which can make the optical components move out of collimation over time. Its optical tubes are nitrogen-filled and O-ring sealed so they can are submersible to 3.3′, as well as fogproof in all weather conditions.
