Pentax 10×50 Z-Series ZD WP Binoculars

Description

The Pentax 10×50 Z-Series ZD WP Binoculars is a premium roof prism instrument designed for extreme low-light observation, long-range wildlife scouting, and marine navigation. Operating with a 10x magnification and large 50mm objective lenses, this optic provides a 5-degree actual angle of view (50-degree apparent field of view), a 262.5-foot linear field of view at 1000 yards (87.5m at 1000m), an expansive 5mm exit pupil, and an extended 22mm eye relief that guarantees complete optical field coverage without vignetting for eyeglass wearers.

The optical system features hybrid aspherical lens elements paired with phase-corrected BaK-4 roof prisms coated with enhanced dielectric multi-layer mirror coatings and broadband fully multi-coated (FMC) optics, treated with specialized protective coatings that repel dust, water, and grease. Encased in a rigid magnesium alloy chassis clad in heavy protective rubber armoring, the housing measures 6.7 by 5.2 by 2.3 inches (17 x 13.2 x 5.8cm) and weighs 29.6 oz (839.2g). O-ring sealed and nitrogen gas purged to JIS Class 6 waterproof standards (submersible to 1 meter), it features a knurled center focus wheel with a 74.9-foot (22.8m) minimum focus distance optimized for open-country and marine infinity scanning, a right-eye diopter adjuster, helicoid twist-up eyecups, and standard 1/4-20 tripod threading.

Key Features of Pentax 10×50 Z-Series ZD WP Binoculars

Built for demanding outdoor enthusiasts who require high photon gathering and optical precision, this 10×50 roof prism binocular pairs 50mm apertures with hybrid aspherical lens elements. Its nitrogen-sealed magnesium alloy chassis withstands harsh rain and accidental submersion, while the 22mm eye relief and 5mm exit pupil maintain viewing comfort during dawn and dusk watches.

Hybrid Aspherical Optics & Dielectric Prism Coatings

The hybrid aspherical optical elements correct spherical aberrations and field curvature, ensuring that images remain sharp across the perimeter of the field of view. Combined with phase-corrected BaK-4 roof prisms and dielectric reflective layers, the oversized 50mm objective lenses gather abundant light, providing high optical contrast and neutral color rendition during pre-dawn game movements and twilight maritime operations.

Magnesium Alloy Closed-Bridge Body & Waterproofing

The lightweight magnesium alloy housing provides impact resistance against heavy field use while balancing comfortably in the hands. The protective rubber armoring cushions internal components and ensures a steady grip in wet conditions, while the large knurled center focus wheel turns smoothly, supported by an internal focusing mechanism that preserves waterproof integrity without moving external parts.

• Knurled central focus wheel and smooth right-eye diopter ring for accurate focal calibration
• Magnesium alloy closed-bridge chassis rated JIS Class 6 waterproof and nitrogen purged
• Helicoid twist-up eyecups designed to maintain stable eye relief without shifting during use
