Nikon PROSTAFF P3 8x42

The Nikon PROSTAFF P3 8x42 combine bright optical performance, straightforward operation and a durable yet relatively lightweight construction. Multilayer-coated lenses and a high-reflectivity silver-alloy mirror coating on the prism surfaces help deliver a bright, clear and contrast-rich view. The generous 20.2 mm eye relief is especially useful for eyeglass wearers. Turn-and-slide rubber eyecups with multiple click-stop positions make it easy to set the correct viewing position.

Main advantages

Steady 8x magnification

 

The 8x magnification provides useful reach while remaining easier to hold steady than higher-powered 10x binoculars. It is well suited to following birds, wildlife and moving subjects.

 

 

Bright 42 mm objective lenses

 

The 42 mm objectives and 5.3 mm exit pupil provide a bright view in daylight, cloudy weather and lower-light conditions. Relative brightness is rated at 28.1.

 

 

Wide field of view

 

The 7.2° real field of view covers 126 m at a distance of 1000 m, helping users locate subjects quickly and follow movement more easily.

 

 

Waterproof and fog-free construction

 

The binoculars are waterproof to a depth of 1 m for up to 10 minutes. O-ring seals and nitrogen filling help prevent internal fogging. They are not intended for underwater use.

 

 

Durable, comfortable body

 

Rubber armouring provides a secure grip and added protection against everyday knocks. The lightweight body is manufactured from fibreglass-reinforced polycarbonate resin.

 

 

Comfortable for eyeglass wearers

 

The long 20.2 mm eye relief helps eyeglass wearers see the full field of view. Adjustable eyecups allow the viewing position to be customised.

 

 

Comparison with alternatives

 

Compared with the Nikon PROSTAFF P3 10x42, the 8x42 is easier to hold steady and provides a slightly wider field of view. The 10x42 reveals more detail on distant subjects but is more sensitive to hand movement.

Compared with the Nikon PROSTAFF P3 8x30, the 8x42 gathers more light and is better suited to overcast weather and lower-light viewing. The 8x30 is smaller, lighter and offers a wider field of view.

Compared with the Nikon PROSTAFF P7 8x42, the P3 is the more affordable option. The P7 adds dielectric and phase-correction prism coatings as well as an oil- and water-repellent coating on the external lens surfaces.
