Pentax 10×43 Z-Series ZD WP Binoculars

Description

With an unconventional 43mm objective size, the Pentax 10×43 Z-Series ZD WP Binoculars offers a 4.3mm exit pupil and a 315-foot field of view at 1000 yards (6.0-degree actual). Eye relief measures 17mm. This setup provides high resolution, but the 6-degree window requires steady panning to acquire fast-moving woodland targets.

Hybrid aspherical elements and BaK-4 roof prisms run dielectric multi-layer coatings alongside hydrophobic external film layers. Cast from magnesium alloy, the chassis measures 5.7 by 5 by 2 inches and weighs 25 oz (708.8 g). O-ring sealed to JIS Class 6 standards and nitrogen filled, it incorporates center focusing down to an ultra-close 42.7 inches (1.1 m), a central locking diopter, twist-up eyecups, and standard 1/4-20 tripod threading.

Key Features of Pentax 10×43 Z-Series ZD WP Binoculars

Designed for naturalists who split time between distant ridge scanning and close-up botanical study. The hybrid aspheric glass elements keep edge-to-edge distortion flat, while the magnesium body keeps weight balanced during long field glassing.

• 10x magnification through 43mm objective lenses yielding a 4.3mm exit pupil
• Phase-corrected BaK-4 roof prisms treated with dielectric mirror coatings
• Hybrid aspherical lens elements for flat field resolution
• 315 ft field of view at 1000 yd (6.0-degree actual angle)
• 17mm eye relief with multi-stop twist-up rubber eyecups
• 42.7-inch (1.1 m) minimum close focus distance for macro observation
• JIS Class 6 waterproof and nitrogen-purged magnesium alloy frame
• 25 oz chassis with central locking diopter wheel

Aspherical Glass & Dielectric Coatings

Aspherical lens surfaces virtually eliminate field curvature, keeping the sight picture flat and sharp out to the field stop. Dielectric prism coatings preserve balanced light transmission across the spectrum, preventing unnatural yellow color bias when observing plumage in deep shade.

Magnesium Chassis & Macro-Focus Mechanics

The magnesium alloy chassis provides high rigidity without adding excessive neck strain on rugged ascents. The center focus wheel operates smoothly through a fast ratio, transitioning from long-range observation down to macro-distance butterfly inspection with minimal finger movement.

• Central focus wheel features a pop-up locking diopter ring to prevent accidental drift
• JIS Class 6 waterproofing withstands temporary submersion and heavy rainstorms
• Twist-up eyecups provide tactile click-stops for rapid eye relief adjustment
