Nikon 7566 overview

  • 1Description

Taking its place at the top as one of their flagship series, the Nikon 8x42 EDG Binocular is outfitted with complementary optical technologies that work together to offer the performance required by tactical professionals and discerning hunters, birders, and outdoor enthusiasts.

Every part of the light path gets special attention to improve the view. This starts at the objective lenses through the use of anti-reflection fully multi-coated extra low-dispersion (ED) glass; moves to the prism system, which is phase-corrected and dielectric-coated; and finally comes to the eyepieces, which employ a field-flattener lens system. Together these systems maximize light transmission, eliminate internal interference, and correct spherical and chromatic aberrations to produce bright and clear high-contrast images with accurate color fidelity across the distortion-free field of view. A moderate magnification brings subjects in for observation while preserving a wide exit pupil. The 42mm objectives boost light-gathering ability without the bulk and weight of larger models, which improves the low-light performance for better and brighter views in challenging conditions such as during the early morning and late evening.

Built for comfort and durability, the body design is ergonomically shaped to fit well in the hand for a balanced feel. The chassis is made of a lightweight and durable magnesium alloy that is wrapped in a protective slip-resistant rubber armor. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and submersible to almost 20 feet, and resistant to internal fogging when moving through extreme temperatures or weather conditions. Nikon includes a set of removable angled eyecups that mold to the side of the user's eye socket. These keep stray peripheral light from interfering with the view and eliminate distractions during viewing.

Optical Performance
  • Moderate 8x power magnifies the view while preserving the exit pupil for better low-light use
  • 42mm objective lens diameter improves low-light performance without excessive bulk or weight
  • Roof prism light path helps to maintain a slim profile for easier and more comfortable handling
  • Extra low-dispersion glass reduces chromatic and spherical aberrations for increased contrast, improved color rendition, and sharpness without distortion across the entire field of view
  • Highly reflective dielectric prism coatings minimize internal light loss to maintain image brightness and improve contrast and clarity
  • Phase-corrected prisms eliminate internal interference in the light path to improve contrast and resolution
  • Anti-reflection, fully multi-coated optics produce bright, high-resolution images
  • Field-flattener lens system corrects lens-edge distortion for clearer views at the edge of the field of view
  • Apparent angle of view approaches wide angle to present an immersive observational experience
  • 403' field of view at 1000 yards
Use and Handling
  • Short closed-bridge design offers more room for the hands while providing a stable platform for the internal focusing mechanism
  • Large slip-resistant center focusing wheel is easy to manipulate in cold or wet weather, or while wearing gloves
  • Locking dioptric correction allows user to correct for optical prescription for sharper views
  • 56-72mm interpupillary adjustment range
  • Turn-and-slide twist-up/click-stop rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter
  • Long 19.3mm eye relief helps to reduce eye strain and improves viewing comfort
  • Comfortable 5.25mm exit pupil will completely cover most pupils as they open and dilate in low light
Construction Details
  • Magnesium alloy helps to reduce weight without sacrificing strength or stability
  • Textured rubber armor protects against bumps and impacts while providing a slip-resistant grip — especially in cold and wet weather

Nikon 7566 reviews

8x42 EDG Binocular is rated 4.5 out of 5 by 4.
Rated 5 out of 5 by from Superb in every way Anyone considering the EL Swarovision bins should test out the Nikon EDG. This is a spectacular product and clearly deserves to sit alongside the Swarovision as among the best binoculars available. The optics are just perfect with amazing sharpness, clarity, and contrast across the field. The lack of eye fatigue after several days of use is just amazing. I own the Swarovision. The Nikon keeps my eyes feeling a little bit fresher. No knock on the Swarovski EL SV which is truly spectacular in itself. These are bright binoculars, and again, I can't tell any significant difference in brightness compared to the Swarovision. It's not as bright as the SLC, but that's to be expected with the field flattener element. Weight is similar to the Swarovski. In the end, you have to prefer what you like holding in your hand. But potential buyers will hopefully get past the European snob appeal of the big three and strongly consider this outstanding binocular.

Rated 5 out of 5 by from Spectacular In over thirty years of using binoculars, including a number of high end ones, I can honestly say that these are the finest I've seen. Pick any feature- optical quality, ergonomics, focusing, weight, feel or quality of manufacture- this is as close to perfect a binocular as I can imagine. There's simply nothing Nikon didn't get exactly right.

Rated 4 out of 5 by from Beautiful Glass These are awesome binoculars. The light transmission is absolutely brilliant. I would be happy to give such a superior pair of optics 5 stars execpt for a simple and aggrevating problem. The front objective covers (rubber with nice attachment design) will NOT stay closed.It is jsut amazing how Nikon could produce the best optics and goof up a simple cap design.

Rated 4 out of 5 by from Optically awesome, but some frustrating quirks The Nikon EDG 8x42 (new model) binoculars are marvelous optically. Viewing birds or scenery through them is a pleasure. Perhaps the brightness is not quite as high as some other premium binoculars (most notably Zeiss), but this seems to be because Nikon wanted to create a comfortable image without glare or excessive contrast. The binoculars are also a pleasure to use in most respects, as the focusing is smooth, the surface has a pleasant, gripable finish, and the binoculars fit comfortably in my hands. The binoculars come supplied with a handsome leather case, plu two sets of rubber eyecups, one of which has a "winged" design to block out stray light. Given the very high price of these binoculars, one would expect their durability to be top notch. In most respects, these optics are solidly made. However, I have found two annoying quirks that caused me to take one star off in creating this review, and actually, part of me was tempted to knock off another (if half stars could be awarded I would rate the binocs 3.5 stars). First, the paint (?) on the surface of the focusing wheel is prone to chipping. This is annoying, as one would think that the outer surface of the binoculars would be designed to be resistant to surface damage stemming from normal use. What is worse, the standard, thin rubber eyecups are prone to falling off at inopportune moments. They are just kind of placed� over the tops of the eyepieces, not stuck on firmly. What's worse is that Nikon's policy related replacing small, lost parts is just plain stupid. I lost one of these rubber coverings during a trip, and upon my return I called Nikon to ask whether I could buy one (or several) of these thin rubber pieces. I was told I MUST send the binoculars in to Nikon "for repair." This cost a pretty penny in shipping fees, and left me without the binoculars for some weeks. During a subsequent trip yep, the rubber eyepiece covering came off again. This time, I was able to find the wayward part (on the floor of my car) and, wanting to avoid a third such episode, I glued it back onto the eyecup. Nikon apparently does not adhere the rubber to the eyepiece because the company figures you might wish to switch to the "winged" eyecups. Fine, but then at the very least Nikon should supply replacement cups conveniently at a low cost, or even free, as is the policy of other premium binocular manufacturers such as Leica, Zeiss, and Swarovski.� Frankly, if I had to choose again which of the elite model binoculars to purchase, I would NOT buy these. They are terrific in the field, but I never quite have gotten over the paranoia that another rubber piece will fall off or that the surface will chip further.
