Nikon 7540 overview

  • 1Description

An ideal companion during long days in the field, on a stand, or at the range, Nikon's black 8x42 Monarch 3 ATB Binocular is engineered for comfort and performance.

Featuring silver-alloy coated and phase-corrected roof prisms with anti-reflection fully multi-coated optics, the Monarch 3 produces bright and clear high-contrast images with accurate color rendition across the entire field of view. Its 8x magnification brings subjects up close, but without the noticeable hand shake often associated with higher power optics, while the 42mm objectives boost its light-gathering ability to improve views in challenging light such as during the pre-dawn and late evening hours or in foggy and cloudy weather. With the combination of prisms, optical coatings, and an exceptionally long eye relief, users can enjoy a comfortable and immersive observational experience in most lighting conditions.

Complementing the optical performance are construction details that make this binocular durable and comfortable to use. It has a lightweight, reinforced polycarbonate ATB chassis and is protected by rubberized armor that is accented with indented palm rests to give it a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A one-piece ocular rainguard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them, and the objective lens caps are also tethered to keep them safe from being lost on the forest floor.

Optical Performance
  • 8x power magnifies objects without sacrificing field of view or exit pupil
  • 42mm objective lenses improve light-gathering ability without adding excessive bulk or weight
  • Roof prism light path ensures optical tubes remain thin for a compact form factor
  • Phase-corrected prism coatings reduce internal interference to improve light transmission, contrast, and resolution
  • Anti-reflection fully multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
  • High-reflectivity silver-alloy prism coatings reduce internal diffraction to further improve light transmission and contrast
  • 330' field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
  • Large slip center focus wheel allows for precise focus control, even while wearing gloves
  • Right eye dioptric adjustment collar helps to compensate for individual eye prescription
  • 56-72mm interpupillary distance range allows easy use by a wide variety of people
  • Twist-up/click-stop rubber eyecups for use with or without eyewear
  • Exceptionally long 24.1mm eye relief helps to reduce eyestrain and improves viewing comfort
  • Wide 5.25mm exit pupil will completely cover most pupils as they open and dilate in low light to keep the full scene in view
Construction Details
  • Environmentally friendly Eco-Glass is made without lead or arsenic
  • Lightweight and durable fiberglass-reinforced polycarbonate chassis
  • Chassis material is temperature resistant, preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus
  • Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
  • Indents on the sides of the optical tubes are ergonomically placed where the hands naturally fall for a more comfortable feel in the hand and a more secure grip
  • Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
  • Tethered fold-down objective lens caps prevents losing them during observation sessions
  • Weight: 25 ounces

Nikon 7540 reviews

8x42 Monarch 3 ATB Binocular (Black) is rated 4.7 out of 5 by 45.
Rated 5 out of 5 by from Lives up to its reviews I've had a pair of Nikon birding binoculars for almost twenty years. They've served me well, but optics have improved and the price has gone down for good binoculars, so I started researching before I bought a new pair. I was surprised at the unanimity: every article, magazine, review, and website seemed to recommend the Monarch 3's for anyone not ready to pay thousands for German binoculars. Now that I've had mine for a while, I can only agree. Super-sharp image, especially in low light; quick focusing; rugged construction. Outside Magazine, the Cornell Laboratory of Ornithology, and many, many other testers can't be wrong!

Rated 4 out of 5 by from Great Binos - Look No Further Been looking for a good pair of binoculars for birding, outdoors & hiking that feel comfortable with glasses. They're waterproof, not very heavy, very clear bright quality lens.The one confusing thing about them is that they come with a diopter adjustment ring on the right eyepiece but it does not turn.I would have given them 5 stars, except the eye piece lens cap fits loose and doesn't stay on very well. This is minor since I don't have it hanging from my strap and only put it on when I store the binoculars.Overall I have been very pleased with them. Experienced birders highly recommend these as the best binos equivalent to much more expensive ones.

Rated 4 out of 5 by from Good Value Optic I am no expert on binoculars; however, these seem well made and the image is sharp. Finally, I have a pair that allows me to see the whole image with my glasses. My other pairs created a peep hole effect with glasses or a slight loss of clarity without glasses. The rotate and click stop eye cups are very nice, but I wish there were one or two more click adjustments. I do find the center focus adjustment a bit too easy to turn while the right eye focus is much firmer. Also, the large objective covers tend to pop off too easily, but at least they stay attached to the binoculars. The rear covers also stay attached to the neck strap and have a different type of fitting than the front. Overall, just what I wanted at a price I could justify.

Rated 4 out of 5 by from Good Value These are great binoculars for birding. Another reviewer claimed that these were the #1 rated birding binoculars, but that is incorrect. That would be the Monarch 5. The Monarch 5 has the following advantages: slightly smaller, lighter, better prism coating (brighter), and closer minimum focus distance.The advantages of the Monarch 3 are lower price and longer eye relief. However, the longer eye relief is not necessary for any normal eyeglasses. I have to turn the eyecups out to the first click in order to use them with my glasses. Still, the lower price outweighed the advantages of the Monarch 5 for me.

Rated 4 out of 5 by from Very good birding binocular I was looking for a good pair of binoculars for birding that had long eye relief because I wear glasses and the Monarch 3 8x42 is exceptional. Because the eye relief is so long, this is the first pair I've owned that I didn't have to put the cups down all the way. I like that they are waterproof, they aren't to heavy, optically very clear and bright and come at a good price point. I would have given them 5 stars, except the eye piece lens cap fits loose and doesn't stay on very well. This does not bother me as I prefer not to have it hanging from my strap when in use and only put it on when I store the binoculars. Overall I have been very pleased with them.

Rated 5 out of 5 by from Great value for money, well made Nikon makes high-end roof-prism binoculars that cost $2,500 or more. Those are great for people who must use them day in and day out, in all kinds of weather and lighting, and demand nothing but the very highest optics. The 8x42 Monarch for a couple of hundred bucks gives you over 80% of the value for like 10% of the price. The construction is not as robust as the high end models. But if you are a casual user, and you take good care of them, and don't bang them up every day, and if you're not critically examining white picket fences in bright sunlight for possible purple or green fringing, you are likely to be quite pleased with these. The eye relief is generous, and should accommodate eyeglass wearers, but every binocular has some fit issues, depending on an individual's physiology. So you have to test it to see if it works for you.

Rated 5 out of 5 by from Second to none I booked a trip to Alaska and was in the market for a binocular to get up close with the local wildlife. I chose Nikon because their glass is second to none and I guarantee you that I was not disappointed. The optics are crystal clear, even in low light conditions. It is without reservation that I would highly recommend the 8x42 Monarch for anyone looking to get up close and personal with nature under a variety of conditions.

Rated 4 out of 5 by from Good Waterproof Binoculars This was the first pair of binoculars I've owned, and I didn't try many when I bought them, so I don't have much to compare them to. I got them because I wanted a good pair of waterproof binoculars in this price range, mostly for hiking and canoeing. Compared to my 8x21 Pentax, these are significantly heavier, larger, and more expensive, but also higher quality. They are waterproof too, unlike my Pentax. I'll probably save these for canoe trips and day hikes, and use my lighter Pentax on overnight hikes. My main complaint is the caps fall off far to easily.
