Nikon 8x42 ProStaff 7S Binocular (Black)

Nikon's black 8x42 ProStaff 7S Binocular is part of the flagship line of their ProStaff series and comes outfitted with an array of optical and design features to give users the ability to discern details of distant subjects—in even the most challenging light and harshest weather.

It features phase-corrected roof prisms that have been further treated with highly reflective mirror coatings, and anti-reflection fully multi-coated optical surfaces that work together to maximize light transmission, while limiting internal diffraction and interference, to produce bright and clear high-contrast images with accurate color rendition across the entire visual spectrum. The 42mm objectives boost its light-gathering ability to improve views in challenging light such as at dawn and dusk, or in foggy and cloudy weather, without the bulk and weight of larger-objective models. Its comfortable exit pupil, long eye relief, and spacious field of view help to minimize the movement of the horizon line on rough or rolling seas to limit disorientation when using it on a boat. This allows users to enjoy an immersive observational experience from early morning to late evening.

Complementing the optical performance are construction details that make the binocular durable and comfortable to use. It has a lightweight and corrosion-resistant reinforced polycarbonate resin chassis and is protected by black rubberized armor that is accented with textured palm pads to give it a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and submersible, as well as resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A tethered one-piece ocular rainguard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them. The objective lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor.

Optical Performance
Moderate 8x power magnifies without sacrificing the exit pupil for enhanced low-light viewing
42mm objective lenses improve light-gathering ability without adding excessive bulk or weight
Roof prism light path ensures optical tubes remain thin for a compact form factor
Phase-corrected prism coatings reduce internal interference to improve light transmission, contrast, and resolution
Highly reflective mirror coatings on prism surfaces reduce internal light loss and diffraction for brighter and sharper views
Anti-reflection fully multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
356' field of view at 1000 yards
Use and Handling
Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
Large slip center focus wheel allows for precise focus control, even while wearing gloves
Right eye dioptric adjustment collar helps to compensate for individual eye prescription
56-72mm interpupillary adjustment range
Twist-up/click-stop rubber eyecups for use with or without eyewear
Exceptional 19.5mm eye relief helps to reduce eyestrain and improves viewing comfort
Comfortable 5.3mm exit pupil will cover most pupils as they open and dilate in low light to keep the full scene in view
Construction Details
Environmentally friendly Eco-Glass is made without lead and arsenic
Lightweight and durable fiberglass-reinforced polycarbonate chassis
Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
Textured black rubber armoring protects against bumps and impacts while providing a slip-resistant grip, especially in cold and wet weather
Textured, ergonomically placed palm pads improve grip stability and comfort
Nitrogen filled and O-ring sealed to be waterproof and submersible to 3.3' (1m) for up to 10 minutes and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when binocular is hanging from the neck
Objective lens caps can be clipped to neck strap to avoid losing them during observation sessions
