Nikon PROSTAFF 7S 8 x 30 Binoculars

Optical Performance

Moderate 8x power magnifies objects while yielding a larger exit pupil and wider field of view compared with higher-power optics for a more comfortable viewing experience

30mm objective lenses improve light-gathering ability compared with smaller-objective models without adding excessive bulk or weight

Compact roof prism design ensures slim optical tubes to help maintain a slim form factor

Anti-reflection fully multi-coated optics maximize light transmission to produce bright and clear high-contrast images

Phase-corrected prisms eliminate internal interference in the light path to improve contrast and resolution

Highly reflective mirror prism coatings limit light loss to keep images bright and sharp

Generous 341' field of view at 1000 yards helps to minimize the appearance of visible hand shake that is common when holding high-power optics

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

15.4mm eye relief helps to reduce eyestrain and improves viewing comfort

3.8mm exit pupil

Construction Details

Environmentally friendly Eco-Glass is made without lead or 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

Light 14.5-ounce weight
