The Nikon EDG 8x42 model binoculars also include additional features such as specific Nikon lens technology, turn and slide rubber eye-cups, a "roof" type glass prism, a dual focus adjuster knob for both eyepieces, and a body made up of environmentally safe materials. Nikon claims the EDG series binoculars are designed with a durable body design to last in a plethora of conditions. The 8x42 is also equipped with a high eye-point view design to allow users with prescription glasses the opportunity to use the binoculars clearly as well.
The Nikon EDG series of binoculars were designed to provide quality equal to that of it's European competitors Swarovski, Zeiss, and Leica.
What separates the EDG 8x42 model from the other series EDG models is the ratcheting eye-cup adjustments, under-body thumb contours for easier grip, a "no fault" warranty repair or replacement policy, and the O ring sealed body that is filled with dry nitrogen to help eliminate fog and keep the model waterproof.
