FAQ's

Real field of view
Real field of view is the angle of the visible field, seen without moving the binoculars, measured from the central point of the objective lens. The larger the value is, the wider the viewfield available. For example, binoculars with a wider field of view are advantageous for locating fast-moving wild birds within the viewfield. This also applies for finding small nebulas or a cluster of stars in astronomical observations.

http://g-ecx.images-amazon.com/images/G/01/electronics/binoculars/nikon/RealField_of_View._V202987058_.jpg

Apparent field of view

Apparent field of view is the angle of the magnified field when you look through binoculars.
The larger the apparent field of view is, the wider the field of view you can see even at high magnifications.

With the conventional method used previously, the apparent field of view was calculated by multiplying the real field of view by the binocular magnification. (With this formula, apparent field of view wider than 65˚ is called wide field of view.)

After revision, Nikon's figures are now based on the ISO 14132-1:2002 standard, and obtained by the following formula:

tan ω' = τ x tan ω
Apparent field of view: 2ω'
Real field of view: 2ω
Magnification: τ
(With this formula, apparent field of view wider than 60° is called wide field of view.)

http://g-ecx.images-amazon.com/images/G/01/electronics/binoculars/nikon/ApparentField_of_View._V202987062_.jpg

For example, the apparent field of view of 8x binoculars with an 7.0°real field of view is as follows:
2ω' = 2 x tan-1 (r x tan ω)
= 2 x tan-1 (8 x tan 3.5)
= 52.1
°

Relative Brightness
Relative brightness value is obtained by squaring the diameter of the exit pupil. The greater the relative brightness is, the brighter the image will be. With 8x42 binoculars, the brightness is (42÷8)2= 28.1. This means that if the magnification is the same, the larger the effective diameter of the objective lens, the brighter the image will be.

Do binoculars with the same exit pupil offer the same brightness?

No. Brightness may vary even if the exit pupil is the same. This is because the amount of light reaching the viewer's eyes varies according to the number of lens elements and quality of lens/prism coatings. Superior optical design and highquality coating greatly contribute to the brightness of binoculars. Brightness values specified in product brochures, etc. are theoretical ones calculated in the design process. Please note these factors when comparing actual brightness values.

Prism Coatings
Multilayer coating is also applied to prisms to raise transmittance. A roof prism system has one surface that does not feature total internal reflection, so vapor deposition with metals, etc. must be used to raise the reflectivity of this surface. Also, phase-correction coating on roof surface ensures high-contrast images.
*Binoculars' brightness and contrast are affected by not only prism coatings, but also the number of objective lens and eyepiece lens, and types of coatings.


http://g-ecx.images-amazon.com/images/G/01/electronics/binoculars/nikon/Coatings._V202987056_.jpgMetal-vaporized, high-reflectivity prism coating
Using vacuum-vaporization technology, metallic material such as aluminum or silver is applied to the reverse side of a prism surface that is not totally reflective. This raises the reflectivity of the prism mirror surface.

Dielectric high-reflective multilayer prism coating
This coating features reflectance that exceeds 99%. By utilizing light interference, this coating assures high reflectivity across the full visible range, and ensures high color reproducibility.
http://g-ecx.images-amazon.com/images/G/01/electronics/binoculars/nikon/ReflectiveCharacteristics._V202987021_.jpgReflectance characteristics of prism coatings on mirror surface
The horizontal axis indicates the wavelength of light. The vertical axis indicates the reflectance of light.
Binoculars' brightness is determined not only by the reflective mirror, but also by the total optical system such as the number of lenses and quality of coatings.
Phase-correction coatinghttp://g-ecx.images-amazon.com/images/G/01/electronics/binoculars/nikon/PhaseCorrection._V202987059_.jpg
A roof (Dach) surface can cause phase shift of light that affects image resolution. This phenomenon is caused by phase differences arising from total light reflection on a roof (Dach) surface and it can occur with even a perfectly processed prism. Phase-correction coating is applied to the surface to minimize loss of resolution, ensuring high-contrast images.

Twilight Factor
The factor that has the greatest impact on resolution or image detail, will be dependent upon the amount of light available during the time of observation. During daylight hours, when your eye pupil size will be only about 2 to 3mm, magnification will be the principal factor in image resolution. At night, with the eye pupil dilated to 6 to 8mm, aperture size is the controlling factor. In twilight conditions both of these factors control resolution effectiveness and the twilight factor is the term that compares binocular performance under these conditions.

The twilight factor is calculated by taking the square root of the product of the magnification and the aperture. The higher the twilight factor, the better the resolution of the binocular when observing under dim light conditions. For example, a 10 X 40 (twilight factor 20) would effectively resolve better under these conditions than a 7 X 35 (twilight factor 15.4) even though the 10 X 40 has a smaller exit pupil. Remember, however, that the twilight factor does not take into account the transmittance or quality of the optical system.

Color Name: BlackSize Name: 8x42
I've written a review about the last iteration of these binoculars and I won't repeat it here. Briefly, these are the best binoculars you can get without spending big bucks, and I think they are the cheapest binoculars you should even consider buying (while there might be an exception to this, cheaper binoculars are bad enough to be worthless and a complete waste of money). These binoculars are three times as good as what you can get for $100 and 90% as good as what you can get for $2,000. They are better than most similarly priced binoculars, and better than many much more expensive binoculars.

Since this is one of the most common binoculars bought by beginners (for good reason), I thought it would be helpful to have a breakdown of the uses of the different magnifications as many buyers have probably not used binoculars extensively. I am mostly into birding and wildlife watching, so beware of that bias if your needs are different.

Don't know what size binoculars to get? Probably just get the biggest ones you can afford, I mean, more magnification is better because you see more, right? Not really. There are a number of trade-offs associated with high magnification. This will help you decide what size is best for you (hint, if you are reading this, 8x42 is almost certainly the best choice for you).

Binoculars have two numbers such as 8x42 or 10x50. The first number refers to magnification, typically 8 or 10, but others also exist (6, 7, 12...). The second number refers to the size of the objective lens (that is the big piece of glass farther from your eye) which in turn determines light gathering potential. These nikon monarchs are offered in 8x42, 10x42, and 12x42 sizes.

Color Name: BlackSize Name: 8x42
I purchased these based on the performance review from Cornell. I am thouroughly pleased and actually purchased a second pair for my wife.

The low light performance of these was more than adequate for our birding needs in early morning or late evening. The brightness is astonishing compared to a binocular of lesser quality. I will never go back to cheap binos. These have helped tremendously bringing our birding experience to the next level. They offer a superb level of contrast and sharpness required for bird identification. I can easily see markings on a sparrow at 50 feet or more in low light. The eye relief is great and having retractable eyecups, even works well with eyeglasses. These binos are meant to be used heavily, just about bulletproof in most conditions.

I would advise people to change out the neckstrap with a harness. My neck never hurts and they don't swing with a harness. The Leupold harness is fantastic. If you are a birder and want to make a good experience and great one, pull the trigger on these. I really think you will be pleased.

As for the 8 x 42 or 10 x 42 debate... If you need low light performance and are watching moving targets such as small birds or the like, I feel the 8 x 42's are the way to go. If you have bright conditions,very steady hands and a still target the 10 x 42 is worth looking at. Try out a pair of each magnification at your local sporting goods store if possible and you decide.

These binoculars are mostly just like the old Nikon Monarchs, with maybe just a little more light in low light conditions. An excellent pair of binoculars for the price, five years ago binoculars of this quality would have been more like $500-600. An especially cool feature of all the Nikon Monarchs is the close focus distance, which with my eyes is probably even a little under four feet. If you like looking at butterflies and dragonflies as well as birds, these binoculars are an excellent choice for their price tag.

Color Name: BlackSize Name: 10x42
I purchased my pair of Nikon Monarch's about 2 years ago. That model did not have the current Dielectric prism coating and it had a different look and feel then the new version. I had the same problem that MANY people have had with the eye cups. If you do not twist them down after use, and you drop or bump the cups on something, they will crack and eventually break off. After making do with just one cup (when is a good time to send in binoculars, birding is a hobby year-round for me) I had a mishap while kayaking that caused some condesation to enter the prism. I finally caved in and sent them back to Nikon for repair.

After a week Nikon sent me an invoice stating that it would be COMPLETELY covered in repair and shipping charges. After waiting another week I recieved what I believed to be my old, refurbished pair of binoculars. You could imagine my suprise when I opened the box to discover a brand new pair of the new model of Monarch's. Nikon replaced my binoculars free of charges including shipping!

I have noticed an increase in the quality of the image that they provide in low light conditions. For the price and quality (in both product and service), I whole heartedly recommend this product!

Color Name: BlackSize Name: 8x42
Buying these binoculars was quite possibly my best online purchase ever. I bought them about two years ago after a friend got me into birding. I did a lot of research before buying my bins, both online and more informally by talking with fellow birders and nature lovers. I settled on these because they were relatively inexpensive, durable, and lightweight, and because they came with the imprimatur of the Ornithology lab at Cornell--which considered them one of the best two or three pairs of entry-level binoculars. I have not been disappointed once. These binoculars produce a bright, crisp image; there's very little distortion, even at the edges. They work well in low-light situations, which is especially important to birders. They are rugged and waterproof. They come with a 25-year warranty, but I doubt I'll ever have to take advantage of it. And they have an amazingly short focal distance of about six feet. This is great for people who want to watch butterflies and other insects, but not so useful for birders in the wilderness. If you have feeders in your backyard and can get close to them without disturbing the birds, though, they will reveal the beauties of common birds like house sparrows and starlings in ways you've never experienced. I can sit in my chair on the porch and watch cardinals feeding on safflower seeds just six or seven feet away. Seeing the male select a seed and give it to his partner, up close in my binoculars, always reminds me how magical the natural world is. Even the small slice of it in my yard. I've recommended these binoculars to about a dozen friends (fellow birders, friends, family, etc.), and all have been satisfied. I recommend them to you, too.
