Nikon Introduces 56mm models of MONARCH 5 Binoculars

July 9, 2013

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of three new 56mm-diameter models of its popular MONARCH 5 series binoculars. This follows the launch in May 2013 of models with a 42mm-diameter objective.
The new binoculars come in three configurations: 8x56, 16x56 and 20x56. They all achieve bright images even in dark conditions and even at the low magnification of 8x. The 16x and 20x models also provide a wide field of view so the user can easily spot a subject from a long distance.
ED (Extra-low Dispersion) glass is used in all models to minimise chromatic aberrations. Brighter images and more natural colours are ensured by the employment of a dielectric high-reflective multilayer prism coating. These and other features make the new models ideal for professionals engaged in nature observation and protection. Birdwatchers will love them, too.

MONARCH 5 16x56

MONARCH 5 20x56

Key Features

  • Extra-low dispersion (ED) glass for chromatic aberration compensation and clearer viewing
  • Dielectric high-reflective multilayer prism coating ensures superior transmittance uniformity across the visible range resulting in bright images and more natural colours
  • All lenses and prisms are multilayer-coated for bright images
  • Phase-correction-coated roof prisms for high resolution
  • Long eye relief design ensures a clear field of view, even for eyeglass wearers
  • Close focusing distance: 7.0m (8x56), 5.0m (16x56/20x56)
  • Eco-glass optics that are free of lead and arsenic are used for all lenses and prisms
  • Waterproof (up to 1m/3.3 ft. for 10 minutes) and fog-free with nitrogen gas
  • Turn-and-slide rubber eyecups with multi-click facilitate easy positioning of eyes at the correct eyepoint
  • Rubber armouring for shock resistance and a firm, comfortable grip
