Exclusive Nikon optical
technologies
The EDG brand was born of Nikon’s
commitment to provide a premium
lineup of the finest instruments in the
field of sport optics.
Thanks to Nikon’s many leading-edge
lens technologies — including our ED
glass, dielectric high-reflective
multilayer prism coating and advanced
multilayer coating — these exceptional
products are able to deliver a
spectacular field of view.
With EDG, you’ll experience a world of
wonders beyond your wildest dreams.
•
Nikon’s legendary ED (Extra-low Dispersion) glass lenses
Nikon’s legendary ED (Extra-low Dispersion) glass lenses effectively compensate for
chromatic aberrations to provide images of superior contrast and outstanding
resolution.
•
Field flattener lens system
Nikon’s field flattener lens system technology minimises curvature of field —
aberrations that occur when focusing on the centre of the field of view causing the
periphery to go out of focus and vice versa — and delivers sharper, clearer images
all the way to the lens periphery.
•
Dielectric high-reflective multilayer prism coating
Dielectric high-reflective multilayer coating is applied to a roof prism unit that does
not feature total internal reflection. This boosts light reflectivity of more than 99%
(designed value) for the full visible range, giving you clearer whites and a sharper,
brighter, more natural vision across the entire field of view.
•
Phase correction coating
Phase shift of light is caused by phase differences arising from total light reflection
on a roof (Dach) surface. Phase-correction coating is applied to the surface to
minimise loss of resolution, ensuring high-contrast images.
•
Brighter images, even at twilight
Advanced multilayer coating is applied to all lenses and prisms to increase light
transmission and to reduce flare and ghosting for super-bright, razor-sharp images,
even at dawn and dusk.
•
Eco-glass optics, environmentally safe materials
All lenses and prisms are free of lead and arsenic.

Dual focus knob with dioptre
adjustment
Larger focus knob for easy operation.
Pull out to adjust dioptre (left), push in
to focus (right).
•
Turn-and-slide rubber eyecups facilitate easy positioning of eyes
at the correct eyepoint
For non-eyeglass wearers, use the eyecups in the extended position. For eyeglass
wearers, use them fully retracted. Eyecups can be adjusted to any of four click stops,
offering fine adjustment that meets your needs.
•
High-eyepoint design for a clear field of view, even for eyeglass
wearers
•
Horn-shaped detachable eyecups
Ergonomically designed horn-shaped eyecups block
peripheral light to give you a clearer field of view.
•
Comfortable, ergonomically designed strap
Designed for comfort, even during long days of use.
The strap length is easily adjusted without having to
remove it from your neck.
•
Short bridge style for easy grip
•
Durable design
Sturdy, lightweight die-cast magnesium alloy body.
•
Waterproof (up to 5m/16.4 ft. for 10 minutes)
Waterproof/fogproof construction features a nitrogen-filled body with O-ring seals.
