Pentax 10×43 Z-Series ZD ED Binoculars

Description

Resolve fine plumage details from an agile 6.6-inch near limit and track distant wildlife using the Pentax 10×43 Z-Series ZD ED Binoculars high-performance roof prism optical system. Featuring 10x magnification paired with 43mm objective apertures, this Japanese-engineered field optic delivers a 315-foot linear field of view at 1000 yards (105m at 1000m), an actual angle of view of 6.0 degrees, a 4.3mm exit pupil, and 17mm of eye relief for steady hand-held tracking and detailed target evaluation during mountain hunts and birding excursions.

The optical system features extra-low dispersion (ED) optical glass elements and hybrid aspherical lens components paired with phase-corrected BaK-4 roof prisms treated with dielectric mirror coatings, new enhanced light transmission multi-coatings, and hydrophobic protective outer coatings. Built inside an inner-focus magnesium alloy chassis encased in dark green textured rubber armoring, the housing measures 14.5 by 12.7 by 5.3cm (5.7 x 5 x 2.1 Inches) and weighs 731.4g (25.8 oz). The optical barrels are nitrogen gas filled and O-ring sealed for JIS Class 6 waterproof and fogproof protection against heavy rainfall and brief submersion. Mechanical controls center on a smooth center-focus wheel with an agile 6.6-inch (0.2m) close focus distance, an integrated locking diopter adjustment dial, four-stop twist-up click-stop eyecups, and a standard 1/4-20 threaded tripod adapter socket.

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

Designed for mobile hunters, ornithologists, and outdoor naturalists, this 10×43 roof prism binocular combines hybrid aspherical ED lenses with dielectric-coated BaK-4 prisms. Its close focus capability allows detailed macro inspection of nearby subjects. The nitrogen-sealed magnesium chassis, integrated locking diopter, and hydrophobic lens coatings provide dependable mechanical control and clear sightlines across wet, demanding terrain.

• Hydrophobic and oleophobic protective coatings applied to exposed objective and ocular surfaces

Aspherical ED Glass Elements & Enhanced Light Transmission

The optical train pairs extra-low dispersion ED glass elements with hybrid aspherical lens components to eliminate spherical aberrations and secondary spectrum chromatic fringing, delivering clean color purity across high-contrast edges. Advanced multi-layer antireflection coatings applied to every air-to-glass boundary maximize photon transmission, producing high image contrast and edge-to-edge sharpness in shaded woodland environments. Hydrophobic exterior coatings cause water droplets, condensation, and mud to roll off without leaving residue, ensuring clear vision during sudden mountain storms.

Submersible Magnesium Housing & Integrated Locking Diopter

The rigid magnesium alloy body provides durable protection for internal optical alignments while keeping carry weight to 731.4g for fatigue-free field transport. Textured dark green rubber armoring cushions against physical knocks and offers a firm, secure hold in wet conditions. The inner-focus central barrel operates with fluid mechanical resistance, incorporating an integrated locking diopter adjustment that prevents unintentional setting changes during active bush travel, while four-stage twist-up eyecups maintain stable eye relief for all observers.

• Inner-focus central barrel integrating a pull-out locking diopter mechanism with tactile detents
• Submersible nitrogen-purged magnesium alloy frame encased in non-slip green rubber armoring
• Four-position twist-up eyecups with distinct click-stops ensuring repeatable eye relief alignment
