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.
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
(With this formula, apparent field of view wider than 60° is called wide field of view.)
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)
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?
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.
|Metal-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.
|Reflectance 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.
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.
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.

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.Read more ›
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.
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!
