Nikon proprietary multicoatings, dielectric prism coatings, and phase-correcting coatings give you images that are bright and sharp, with high contrast and a well-balanced and realistic color rendition. And barrel distortion and astigmatism are virtually nonexistent. Whether you’re birding in shadowed woodlands or viewing across open meadows and shorelines, in bright sunlight or under foggy or overcast skies, the Nikon 7 x 42mm EDG will show you all the color and detail in nature that there is to see.

This Nikon 7 x 42mm EDG has a large 6mm exit pupil for bright images in the low light of shadowed woodland glens and evening twilight or under overcast skies. It has a very wide 8° field of view, a close focus under 10’, and an excellent depth of field that make it a delight for close-in birding in addition to being a superb low light binocular. With its fast focusing (less than one and a quarter turns) and wide field, you won’t miss finding that fast-moving life bird with this Nikon.

Features of this binocular . . .

• EDG roof prism optics: State-of-the-art roof prism design using EDG (Extra-low Dispersion Glass). The use of ED glass, the same as that used in multi-thousand dollar Nikon camera lenses, eliminates visible chromatic aberration in this Nikon 7x42mm EDG binocular. Chromatic aberration is an optical defect that shows as the spurious color fringes seen around objects at the edge of the field in lesser binoculars, for example when looking at a crow or starling perched on a telephone wire against a bright cloudless sky. With ED glass, the colors you see are true and pure. There is no color fringing or wash of false color, around eye rings for example, to interfere with an accurate ID with this Nikon EDG binocular.
• Full multicoatings: Every glass surface in this Nikon EDG binocular is fully multicoated with multiple layers of proprietary Nikon antireflection materials for maximum light transmission. Each vacuum-deposited anti-reflection layer is a mere 0.000125 millimeter thick, about 1/500th the thickness of a human hair.
• Dielectric coated roof prisms: The mirrored surfaces of this Nikon EDG binocular’s image-erecting roof prisms are coated with dozens of layers of microscopically-thin vacuum-deposited dielectric materials for superb reflectivity – higher even than silver, the former reflectivity leader. The result is very high light transmission for an extremely bright image, with neutral and realistic color rendition. Plus, there is no possibility of the coatings tarnishing, as can happen with silver prism coatings.
• Phase-correcting prism coatings: Special phase-correcting optical coatings applied to the prisms eliminate the image-degrading effect of light phase cancellation within the prisms, which is common in conventional roof prism binoculars without such coatings. The Nikon EDG phase-coatings provide very high contrast and resolution, which is particularly visible when looking sunwards, where more color and detail is clearly visible in the shadowed areas of backlit or silhouetted birds.
• Open bridge design: The body’s open bridge “quadrangle" design lets your fingers wrap almost completely around the binocular barrels for a natural grip and balance that allows comfortable all-day birding.
• Concealed diopter correction: The Nikon’s large ribbed center focus knob pops up to give you instant access to the continuously-variable diopter correction ring beneath it. Once you adjust the diopter ring to compensate for any differences between the vision in your individual eyes, the focus knob snaps back down into place to lock in your individual diopter correction.
• Armored body: The lightweight and rugged die-cast magnesium EDG body is clad in lightly-textured noise- and shock-absorbing soft-grip black rubber armor. Shallow thumb rests molded into the underside of the barrels allow a comfortable and slip-free grip. A wide and soft neoprene comfort neckstrap makes the light 28.6 ounce weight of the 7 x 42 EDG even easier to carry in the field for hours at a time without neck strain.
• Waterproof and fogproof: This Nikon EDG binocular is nitrogen-filled and O-ring sealed to be internally fogproof in all temperature extremes and waterproof to a depth of 5 meters (16.5 feet) for up to 10 minutes. Inert nitrogen filling also prevents the internal formation of fungus in high humidity climates, such as rain forests. This EDG binocular is designed to operate reliably from the cold of Attu to the heat of Death Valley, from the dry air of the Serengeti Plains to the intense humidity of the rain forests of Costa Rica.
• Long eye relief: The eye relief is specified at a trifle over 22 mm. While this is technically correct, being measured from the last lens surface to where the image is formed, the actual usable eye relief typically measures a few millimeters less. This is due to the eyepieces being recessed into the binocular body to protect them from being scratched by eyeglass lenses during use. A shorter usable eye relief than the technically correct value specified is typical of virtually all binoculars. Vignetting should be virtually non-existent for most eyeglass wearers in any case.
• Twist-up eyecups: The soft rubber-rimmed eyecups retract into the binocular body for eyeglass and sunglass use, rather than rolling down. It takes only a matter of seconds to adjust the eyecup height from unaided eye to eyeglass use. There are four discrete steps built into the twist-up mechanism, so that you can set the eye relief to match your preference.
• Extra light-shielding eyecups: In addition to the standard flat rim eyecups for eyeglass and general use, this Nikon EDG binocular comes with a second set of rubber eyecups. These can be slipped on in place of the standard eyecups in a matter of seconds. They cannot be used with eyeglasses, as each has a non-folding bat wing extension that extends from the side of the eyecup rim back past your eye sockets to rest against the side of your face. These extensions shield your eyes from peripheral light to give you higher contrast views in extremely bright and highly reflective environments – deserts, sunny beaches, open water, snow fields, etc.
• Fast focusing: Less than one and a quarter turns of the comfortably-large ribbed rubber central focus knob moves this Nikon EDG binocular from its closest focus out to the horizon and beyond. While the specified close focus distance is 9.8’, we typically measure it as low as 7’. We can’t guarantee that you will be able to focus that close, so we’ll content ourselves with using Nikon’s 9.8’ close focus figure.
• Neck strap: Your Nikon EDG comes with a wide and comfortable stretchy neoprene neck strap.
• Rainguard: The supplied eyepiece rainguard is made of hinged plastic. A lock knob in the center of the rainguard lets you lock it open at the best angle to fit quickly on your binocular without fumbling when it starts to rain. This is handy if you are the only one to use your binocular, in that the interpupillary distance will always the same. If you share your binocular with others, however, you would probably want to leave the rainguard hinge unlocked so you can quickly accommodate different interpupillary spacing.
• Objective lens covers: Slip-on rubber objective lens covers are standard equipment. The circular center of each lens cover is hinged to swing down and out of the way to give you an unobstructed view when observing, so you can leave the lens covers on your binocular full time if so desired, simply flipping them up for protection and down for unobstructed viewing.
• Soft case: A lightly-padded soft nylon storage case is standard. The case is designed primarily to store the EDG when it is not in use, so no shoulder strap is provided. If you wish to use the case in the field, the binocular neck strap fits through the top flap of the case to act as the case strap.
• Warranty: This Nikon 7 x 42 EDG is protected by Nikon’s standard 25-year Limited Warranty against manufacturing flaws in material or workmanship. In addition, it is further protected by Nikon’s “No-Fault" repair or replacement policy. If this binocular ever requires repair or service not covered by the standard Nikon 25-year warranty, Nikon will repair or replace it (even if the damage or failure was your fault) for only $10, plus return shipping and handling. In essence, the Nikon No-Fault policy says that if you register your Nikon product with Nikon, no matter what happens to that product for the next 25 years you own it, you can send the pieces back to Nikon (including the piece with the serial number) and they will repair or replace it for only $10 plus a small shipping and handling charge.
