The Compact PROSTAFF 7S 8×30 Binocular
Nikons PROSTAFF 7S 8×30 is a sleek looking compact binocular that is built for a variety of outdoor activities and is a great accessory for nearly any outing. Thanks to fully multicoated Eco-glass lenses and Phase-Correction Coated Roof Prisms, the PROSTAFF 7S delivers sharper images that are full of brightness and optical clarity providing an eye catching view of the action around you.
Nikons Advanced Optical System
PROSTAFF 7S binoculars provide high-resolution images with extremely accurate color reproduction, thanks to Phase-Correction Coated Roof Prisms. Multilayer coatings, which provide an even higher light transmittance across the entire visible light spectrum, are applied to all of the lens and prism surfaces that transmit light. This minimizes the loss of light due to reflection, thereby ensuring a more natural, clearer view.
Ergonomic, Rubber Armored Body
A lightweight, ergonomic body design makes the PROSTAFF 7S enjoyable to hold for long periods of time. The central focus knob is intuitive to operate and is very user friendly. Built to handle any environment, the PROSTAFF 7S has a rubber-armored coating to withstand extreme use and provide a non-slip grip, even in the wettest conditions.
Turn-and-Slide Rubber Eyecups
Turn-and-slide rubber eyecups allow users to adjust the eye-relief for a custom fit – providing a full field of view and maximum comfort during extended periods of use.
Waterproof and Fogproof
PROSTAFF 7S binoculars are nitrogen filled and O-Ring sealed for complete waterproof and fogproof performance.

Features
Roof (Dach) Prism Type: Binoculars that emplay a roof (Dach) prism to rectify the image. “Dach” means roof in German. The optical path at the objective side and eyepiece side is virtually straight, making it possible for the binoculars to be compact and slim.
Central Focusing (CF): Binoculars that have a CF mechanism. Focus both left and right eyes at the same time by rotating a central focusing ring. Superior operability.
Full Multilayer Coating: Multilayer coating is applied to transmission surfaces of all lenses and prisms to enhance light transmittance. Provides a brighter and sharper field of view.
Long Eye Relief: High-eyepoint binoculars with eye relief of 15 mm or longer. Eyeglass wearers can also obtain the field of view without vignetting.
Rubber Coating: Body is coated with rubber. It fits securely in your hands for comfortable holding.
Waterproof: Waterproof structure is employed. Nitrogen gas-filled models are resistant to fog and mold.
Applications
Bird watching, nature watching: Binoculars with a wide field of view and 7x to 10x magnification are suited for general nature viewing. Observing whales or birds at a greater distance is more comfortable with 8x to 12x magnification models. For even closer views, Fieldscopes are recommended.
Outdoors, camping, hiking: Rugged outdoor activities demand portability and durability. Models that also feature rubber armoring and waterproofing are ideal when you’re up against the elements. For early morning and evening use, binoculars with a large objective diameter and Nikon’s multicoated lenses are recommended.
Spectator sports: Binoculars that feature a wide field of view and 7x to 10x magnification are handy for fast-moving sports. Zoom type binoculars are also convenient, as they enable quick and easy changes in magnification to suit the viewing situation.
Marine sports, fishing: Waterproofing and durability are essential for these activities. Enhanced brightness and a wide field of view are desirable too. Models that feature vibration reduction are favored for on-board use.
