The Premier Binocular – Sleek and Ergonomic. The Nikon Premier binocular line is engineered by those who know that hunting equipment is going to be pushed to the limits. It is designed for those who search for game for hours and those who demand to be able to judge an animal in fading light. Long considered one of the finest binocular designs in the optics world, the Premier utilizes a sturdy, die-cast magnesium-alloy body that cuts weight without giving up durability. Special fully multicoated optics has multiple layers of anti-reflective compounds on every glass surface for bright, vivid sight pictures. Phase-correction silver coated prisms enhance resolution for excellent detail and the ultimate in color contrast and clear, round images. The ergonomic Premier has durable and protective rubber-armored coating that provides a non-slip grip – wet or dry. The soft-touch turn-and-slide rubber eyecups with multi-click adjustments improve the overall versatility of the Premier binocular for users with and without eyeglasses. The Premier line continues to feature a precise, conveniently located central focusing control positioned for fast, easy focusing. For waterproof/fogproof performance under the most adverse weather conditions the Premier line is O-ring sealed and filled with dry nitrogen. With rugged rubber armor for added durability and a firm grip even in the worst conditions, Nikon guarantees this binocular to be 100% waterproof and fogproof, each is backed by Nikon’s 25 Year Limited Warranty and No-Fault Repair/Replacement Policy.

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.

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.)

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
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 8×42 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.

Prisms
Prisms are what let you see a correctly oriented image when you look through a pair of binoculars. There are two types of prisms in common use, Porro prisms and roof prisms.

Roof prisms are essentially in line inside the optical tubes, and make for a more compact set of binoculars. Roof prism binoculars have straight tubes (the front/objective lens is in line with the rear/ocular lens), and are therefore more compact, an important consideration for the sportsman. They usually have two pivot points between the tubes, and are more difficult to adjust to the spacing of your eyes. Roof prisms can give an optical image equal to the best Porro prisms, but for technical reasons they usually do not. To be really good, roof prism binoculars have to be in the high price class. Do not attempt to economize on roof prism binoculars.

Porro prism binoculars can be identified by their offset tubes; the objective lens is not in line with the ocular lens. The front lenses are usually closer together than the rear lenses, but the reverse can also be true, particularly in compact models. The Porro prism design is usually optically superior to the roof prism design, especially in medium priced class binoculars. Porro prism binoculars have a single pivot between the two halves of the binocular, and are therefore easy to adjust for the distance between your eyes.

Like roof prisms, not all Porro prisms are created equal. BAK-4 prisms are the best; they are made of superior optical glass that produces clearer images. These are what you want in your binoculars. BK-7 prisms are also used, usually in lower priced binoculars. These are satisfactory, but they are inferior to the BAK-4 prisms. Some manufacturers will not tell you what kind of prisms they use, usually because they are of inferior quality. BAK-4 prisms show a truer round, which translates to better light transmission and edge-to-edge sharpness

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.

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.

Phase-correction coating
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.
