Nikon Introduces New EDG Fieldscope Series

March 5, 2009

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to introduce the EDG Fieldscope series, a new Nikon Sport Optics brand.

EDG is pronounced "edge" because the series provides edge-to-edge brilliance and overall leading-edge performance. The optical and mechanical results of the current fieldscope series, which has won plaudits from users around the world, have been enhanced for the new EDG series. The outstanding performance of EDG Fieldscopes, including natural color reproduction and crisp clarity, has been achieved through the use of Extra-low Dispersion (ED) glass. The straight-type models also feature dielectric high-reflective multilayer prism coating.

Both the main bodies and eyepieces of the EDG Fieldscopes are waterproofed with O-ring seals and nitrogen gas, allowing EDG Fieldscopes to be used in adverse weather conditions. Seven kinds of eyepiece are available, providing unparalleled performance in differing environments. The newly developed zoom eyepiece in particular offers superb optical performance with minimized distortion and long eye relief (18.4-16.5mm).
