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.

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.


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.

Product Description


Nikon's Action Extreme series offer lots of features that will be appreciated by those who enjoy the view provided by classically-styled porro prism units. Following the enormously popular Action series, Nikon has made significant improvements. The group still retains the high-refraction prisms with their wide viewing fields, and every model has a tripod adapter threading for easy extended glassing from a stationary position. The 16x50 Action model has a tripod adapter for easy extended glassing from a stationary position. It is ideally suited to tripod use for fully employing its awesome power, with performance in twilight which is commendable. An ideal binocular for big game hunters.

Amazon offered the lowest price and the service exceeded my expectation. Have used them with excellent results at night observing the moon and stars. Much, much better than the much less expensive 10X50 I have been using. Also did some bird watching and found the brightness and color accurracy also much better than the cheaper pair. Another pleasant surprise was the Nikon allowed viewing at a much closer distance really making their range for viewing much more practical. The weight is about the same as the cheaper pair and I can only wish they were half the weight but this weight seems to be about the norm for this size pair. Plan to take them with me on all hikes and trips. They seem to be very well constructed and the rubberized coating makes them easy to use and comfortable. Recommend them to anyone looking for a pair in this size range.

I was looking for bird and animal watching binoculars. And wanted something with significant magnification. 10x and 12x didn't seem like enough to me. 16x is perfect. a little jittery to hold but not a problem. certainly worth it for the increased magnification. i was impressed at how easy it was to sight, line up, and track objects. I thought it would be harder with 16x magnification. definitely recommend these binoculars. great feel, not too heavy, and visuals look excellent to me.

I am not an expert in optics (digital cameras, binoculars, etc) but I can make the difference between good quality and not so good quality. I believe that the Nikon Action 16x50 binoculars fit, by far, in the first category. I was still not sure if I made the right decision when I purchased these, since I red several cons along the multitude of pros. Some of them were shaky image (due to the high zoom), pretty heavy for long periods of watching. All I can say now is that they are true, but these things fade by far in comparison to what this baby has to offer. Namely stunning crystal clear and sharp image (even at the edges), extremely rugged and ergonomic construction, fogproof and waterproof.
All in all, I would give it 10 out of 10 in a heartbeat.

I didn't want a pair of low power binoculars as I plan to do a cruise out of Italy through the Eastern Met. If you have concerns about stability with the 16 power, I suggest a tripod because the unit comes with an adapter but, I bought one made by Nikon specifically for this model. The quality is excellent and the magnification is exactly what I wanted. I don't think you'll be disappointed with this product. I love it.

Bought these binoculars because I couldn't afford the Steiner product w/these specs. I have the Steiner compact binoculars that I bought from Amazon and was so impressed...love them. So I thought I would also buy the larger Steiner binoculars. However, after the sticker shock and then reading reviews on Amazon for the Nikons (and I also have two Nikon cameras that I love), so I thought, lets get these binoculars. I am so impressed and totally love them. Their clarity and ease of use surpassed my expectations. I find I can even use them with or without my glasses...no problem. I highly recommend these binoculars on all levels.

The Nikon Extreme (EX) 16x50 binoculars have a field of view that is a bit too narrow for many uses most binoculars are put to but if you need to pull in really distant views or like to view stellar objects in the nighttime sky they work well. The optics are top notch. I thought about purchasing this product for some tome but the price was a barrier. Then I found them on Amazon at what I considered a workable price. This purchase has proved to be a good one.

Best pair of Binocs I've used - great clarity in vision, also seems to have some increased illumination when viewing at night. Only downside is viewing stars and planets; no problem viewing but you'll need a tripod to stabilize - otherwise the objects are 'jumpy'.
