Olympus 8×42 Pro Binoculars

Description

Leveraging Zuiko camera-lens optical engineering, the Olympus 8×42 Pro Binoculars provides a broad 394-foot field of view at 1000 yards (7.5-degree actual). The 5.25mm exit pupil and 18mm eye relief ensure relaxed viewing. While center sharpness is exceptional, the wide 60-degree apparent field displays minor pin-cushion distortion toward the outer margins.

Professional ED glass elements combine with phase-corrected, dielectric-coated BaK-4 Schmidt-Pechan roof prisms and proprietary ZERO anti-reflection coatings. The polymer-reinforced chassis is clad in textured rubber armoring, measuring 5.2 by 5.5 by 2.1 inches and weighing 23.63 oz (670 g). Nitrogen purged and sealed against moisture, it features an internal center focus wheel reaching an ultra-close 4.9 feet (1.5 m), a -2 to +2 diopter ring, and twist-up eyecups.

Key Features of Olympus 8×42 Pro Binoculars

Engineered for exacting field ornithologists and naturalists who demand true color fidelity and class-leading close focus capability. The 4.9-foot close focus allows macro-like observation of insects, while the Zuiko optics deliver exceptional light transmission.

• 8x magnification through 42mm objective lenses with a 5.25mm exit pupil
• Phase-corrected BaK-4 Schmidt-Pechan roof prisms with dielectric reflective coatings
• Professional-grade ED glass lenses with ZERO anti-reflective multi-coatings
• 394 ft field of view at 1000 yd (7.5-degree actual angle)
• 18mm eye relief with multi-stop twist-up rubber eyecups
• Ultra-short 4.9-foot (1.5 m) minimum close focus distance
• Nitrogen gas purged housing with oil- and water-repellent external lens coatings
• Lightweight 23.63 oz chassis with tethered flip-down objective covers

Zuiko ED Glass & ZERO Coating Technology

Olympus applies its ZERO (Zuiko Extra-low Reflection Optical) lens coatings alongside dielectric prism stacks, pushing light transmission past 90 percent with neutral color rendering. ED glass elements eliminate chromatic aberration along contrast edges, while the exterior oil- and water-repellent coatings allow rain droplets and dirt to wipe off without smearing.

Ergonomic Chassis & Macro-Focus Operation

At just 23.63 oz, the lightweight body minimizes neck strain during all-day birding surveys. The internal center focus wheel operates with exceptionally fast gearing, sweeping from macro distance out to infinity in little more than one turn, while the textured rubber armoring supplies a steady grip in damp conditions.

• Fast center focus dial transitions from 4.9 feet to infinity with minimal finger rotation
• O-ring sealed nitrogen purging protects internal elements from fogging during sudden squalls
• Multi-position twist-up eyecups maintain firm spacing without collapsing under viewing pressure
