Nikon Prostaff 5 10x50

• 10x50 configuration: The combination of 10x magnification and a 50 mm objective lens gives this binocular the reach needed for scanning open ground while keeping a bright, steady image for dawn, dusk and overcast conditions.
• Long eye relief: With 19.60 mm of eye relief, the view remains comfortable for extended observation and works especially well for eyeglass wearers who need to see the full field without strain.
• Roof prism design: The Schmidt/Pechan roof prism layout keeps the binocular slimmer and easier to carry than a bulkier porro design, which matters on long walks, hunts and travel days.
• Fully multicoated optics: Fully multicoated lenses help preserve brightness, contrast and color fidelity, making detail easier to pick out in shaded woodland, at longer distance and in changing light.
• Waterproof and fogproof construction: A nitrogen-filled, sealed housing resists internal fogging and handles wet weather, so the binocular stays usable when temperature shifts or rain move in.

About the Nikon Prostaff 5 Series

The Nikon Prostaff 5 series sits in Nikon’s outdoor-focused lineup as a practical roof prism range built for general field use. Nikon announced the series in 2014, and the family has included 8x42, 10x42, 10x50 and 12x50 models, giving users a choice between wider handheld viewing and more reach or low-light capability. Across the range, the emphasis is on straightforward handling, dependable weather protection and optical performance suited to hunting, birdwatching, hiking and other everyday observation.

A defining trait of the series is its balance between portability and durability. Fiberglass-reinforced polycarbonate resin keeps weight under control while maintaining a solid feel, and the binoculars are built to be waterproof and fog-free with nitrogen gas. Nikon also gave the series long eye relief, which improves comfort during extended glassing sessions and makes the binoculars easier to use with glasses. Roof prisms, central focusing, multilayer-coated optics and rubber armoring complete a design that favors practical field use over unnecessary complexity.

About the Nikon Prostaff 5 10x50

The Nikon Prostaff 5 10x50 is the larger, brighter configuration in the series for users who want more low-light performance than a 42 mm binocular can usually provide. Its 10x magnification offers enough reach for scanning field edges, hillsides, coastlines and distant tree lines, while the 50 mm objective lenses gather more light for early morning and late evening observation. That makes this model a sensible fit for hunting, wildlife watching and general outdoor use where detail at distance matters but conditions are not always bright.

The optical layout uses Schmidt/Pechan roof prisms, which keep the body relatively trim for a 10x50 binocular and easier to pack than a wider traditional design. A 5.00 mm exit pupil helps maintain a bright, relaxed image in subdued light, and the fully multicoated optics support better contrast and more natural color, which is useful when separating animals from shadowed backgrounds or reading terrain detail. The 98.18 m/1000m field of view is controlled enough for distance work while still wide enough to follow movement without feeling tunnel-like.

In day-to-day handling, this model is built for comfort over long sessions. 19.60 mm eye relief gives eyeglass wearers a more complete view, the central focusing system allows quick adjustment as distances change, and the right-eyepiece diopter helps fine-tune the image to the user’s eyesight. Nikon also gives the binocular a waterproof, fogproof, nitrogen-filled construction, so it remains dependable when moving between temperatures or using it in damp weather.

About Nikon

Nikon was established in Tokyo on July 25, 1917 as Nippon Kogaku K.K., and it remains headquartered in Tokyo, Japan. The company introduced its MIKRON compact binoculars in 1921, showing that sport optics have been part of Nikon’s history for more than a century. In 1988, the company changed its name to Nikon Corporation.

Today, Nikon works across imaging products, precision equipment, healthcare, industry, components and digital manufacturing, while its sport optics division covers binoculars, fieldscopes and laser rangefinders. Within binoculars, Nikon’s families include MONARCH, PROSTAFF, EDG, ACULON and High Grade, with each line aimed at a different level of use and refinement. A consistent theme in Nikon sport optics is the use of multilayer-coated lenses to improve light transmission, which is directly relevant to binoculars such as the Prostaff 5.
