Taking design inspiration from their OM-D DSLR cameras, the Olympus 8x42 Pro Binocular comes outfitted with a magnification–objective lens configuration favored by discerning amateurs and professionals all over the world.

Extra-low dispersion (ED) glass with phase-correcting and dielectric coatings on the BAK4 prisms, along with anti-reflection fully multi-coated optics, produce bright and clear high-contrast images with accurate colors and enhanced clarity without distortion, ghosting, or fringing. The wide apparent angle of view presents an immersive observational experience with the ability to take in large areas without having to move. A short 5' close-focus distance lets you make detailed observations of small subjects like hummingbirds, butterflies, dragonflies, or other insects at short ranges when they are at feeders or flowers.

Designed to stand up to constant use in harsh outdoor conditions, the optical tubes are nitrogen filled and O-ring sealed to make them waterproof and fogproof when moving through extreme temperature and environmental variations. Oil- and water-resistant exterior lens coatings cause rain and dew to bead off, while making oil, sap, and other dirt and debris easy to remove without smudges or streaks—ensuring clear views. Olympus includes tethered front and rear lens caps to add an additional layer of protection in the field, with the ability to quickly react to glassing opportunities without fear of losing the caps.

Optical Performance

8x power magnifies view without sacrificing field of view or exit pupil

42mm objective lenses improve light-gathering ability versus smaller objectives while helping to maintain a compact form factor

Compact roof prism light path ensures a slim profile without sacrificing performance

BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion

Extra-low dispersion (ED) glass lens elements produce bright and clear images with accurate color rendition and improved contrast, without fringing

Multi-layer phase-correcting and dielectric mirror prism coatings eliminate internal interference, light loss, and diffraction to improve clarity, resolution, and contrast

Anti-reflection multi-coated optics maximize light transmission to ensure bright and clear images with accurate colors and improved contrast and clarity—without ghosting or flares

Oil- and water-repellent exterior lens coatings make it easy to clean dew, rain, fingerprints, sap, and other materials off the lenses, without streaks or smudges, to ensure clear views

Short 5-foot close-focus distance allows detailed viewing of small birds, butterflies, and insects at feeders and flowers

Wide 60° apparent angle of view presents a spacious field of view to more easily find and track subjects

Generous 394' field of view at 1000 yards

Use and Handling

Closed-bridge configuration offers a solid and stable platform for the focusing system

Large, slip-resistant center focusing wheel is easy to manipulate in cold or wet conditions or when wearing gloves

±2 right- and left-eye dioptric correction allows for precise focusing even for those who normally require corrective eyewear

Twist-up click-stop rubber eyecups for comfortable use with or without eyewear

Tripod mountable with optional adapters for hands-free use to reduce arm fatigue and vibrations

Long 18mm eye relief increases comfort and reduces eyestrain for easier viewing, especially during long glassing sessions

Wide 5.25mm exit pupil will cover pupils as they open and dilate in low light to keep the entire scene in view at all times
