Nikon Introduces MONARCH 5 Binoculars

March 25, 2013

MONARCH 5 10x42

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of its new MONARCH 5 series, three completely redesigned 42mm-diameter binocular models to add to the long-respected MONARCH family of sports optics.

Nikon's highly praised MONARCH 42mm binoculars provide high optical performance in a stylish, easy-to-grip body design. Employing ED lenses and a dielectric high-reflective multilayer prism coating, the MONARCH 5 will be released soon.

Thanks to their high-quality optics, lightweight-yet-robust body, the current MONARCH models have earned an excellent reputation among the outdoor professionals who rely on them. Inheriting the characteristics of its renowned predecessors, the MONARCH 5 series takes advantage of Nikon's long history of optical technology, all while offering enhanced performance in a new, sophisticated design.

The MONARCH 5 series employs ED glass to minimise chromatic aberrations, while a dielectric high-reflective multilayer prism coating delivers brighter images and more natural colours, making these binoculars ideal for outdoor activities where reliable performance is crucial, such as birdwatching and hunting.
