Nikon Introduces MONARCH 7 8×30/10×30 Binoculars
Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of its MONARCH 7 binoculars 8×30 and 10×30. These new models complement the existing MONARCH 7 8×42 and 10×42 binoculars.
Integrating two values that Nikon has consistently pursued, namely, technical perfection and practical utility, the MONARCH 7 8×42 and 10×42 made their sensational debut last year. The new MONARCH 7 8×30 and 10×30 models now join this series, upholding that same level of incomparable optical performance. Brighter images and natural colours are realised by Nikon’s optical technologies such as ED glass (extra-low dispersion glass), dielectric high-reflective multilayer prism coating and phase-correction-coated roof prisms.
Built small and compact, these amazing binoculars are suited for those who seek high-performance products, and also for birdwatching enthusiasts who demand high performance in a compact body.
