Nikon Introduces PROSTAFF 5 Binoculars

July 9, 2013

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of four new PROSTAFF 5 binoculars: the 8x42, 10x42, 10x50 and 12x50.
These new models — even more user-friendly than the existing PROSTAFF 7 range — are perfect for people who are using fully waterproof binoculars for the first time for nature observation and other outdoor activities.
All four offer a bright field of view. Nikon particularly designed the two 50mm models of the series for users who put priority on a brighter field of view as they often observe their subjects in darker conditions.

PROSTAFF 5 10x42
