Nikon Introduces PROSTAFF 3S Binoculars

March 4, 2016

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of the PROSTAFF 3S binoculars, featuring 8x42 and 10x42 models.

These products are the latest additions to Nikon's PROSTAFF series which consists of waterproof, roof (Dach) binocular models.

The new PROSTAFF 3S binoculars feature a 42mm-diameter objective lens — yet they are noticeably lightweight, with compact bodies, assuring superb portability. In addition, the large field of view allows the user to capture the subject easily, making these models particularly appealing to novices.

Other features include prisms with high-reflectivity silver-alloy mirror coating and multilayer-coated lenses that both realise bright and clear viewing. The long eye relief design ensures a clear field of view without vignetting, even for eyeglass wearers. Also, turn-and-slide rubber eyecups with multi-click are provided to make it easy to position the user's eyes at the appropriate eyepoint.

Nikon's new PROSTAFF 3S binoculars are waterproof (up to 1m/3.3 ft. for 10 minutes) and fog-free with O-ring seals and nitrogen gas, making them the ideal binoculars to use for those who like hiking, birdwatching, attending sports events and other outdoor activities.
