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.

https://images-na.ssl-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.)

https://images-na.ssl-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.


https://images-na.ssl-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.
https://images-na.ssl-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 coatinghttps://images-na.ssl-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.

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.

Nikon Action 16x50 EX ATB Binocular review- April 2013. I'm not employed by Nikon nor have my pockets been lined by a company who promotes them. Like many of you out there I sometimes wonder how many reviews have been written by people who were paid to leave a positive word about a product but had never used it personally. I bought these binoculars with my hard earned cash because I wanted a good pair of glasses for watching aircraft on the field where I work at KCHS. I have to say, the reviews that state that they are shaky without something to steady them on are well founded, but that's only because these binoculars have the ability to reach out and bring things from afar to your eyes like no other pair. I don't have that problem really, I find them quite useful for free support without a hard stance or a place to rest my elbows while looking through the lenses. While holding them in a natural stance, the shake is minimal, and I'd rather have these than a lower power such as 10x50. I also read in some reviews that they are heavy, well they aren't heavy. If you are a 72 year old woman then you may find them heavy, but they aren't heavy at all for a man in his late 30's. My co-workers at the airfield have tried them out and they all love the view they see. Watching 737's and MD-88's touch down a mile away with these binoculars gives you the same view that you would see if you were standing 200 feet away from the runway - earplugs not required. Boeing is building the 787 at my location and I've even handed these binoculars to other commercial pilots on the ramp so they can watch the new 787 take off and land .. they love the view and always hand the binoculars back with a huge smile on their face and a gracious heartfelt thankyou.Read more ›

I bought these primarily for hunting and while I have not yet used them for that I have used them around the house watching squirrels and birds and checking them out on distant objects. And I took them on one camping trip. I have been using a old pair of 10 X 50 and wanted a more powerful binocular. I was able to look through a less expensive pair of 16 X 50 Action instead of the Action Extreme in a sporting goods store and determined that I can hold them steady enough to use them. Before buying 16 power binoculars you should know if you can hold them steady or not. Some can, some can't. I'm 63 and have no problem with it but not everyone can. I've found these binoculars to be sharp, bright and clear all the way to the edge of the field of view. They are large and somewhat heavy. The 50 mm lens insures that but that's what it takes to get a bright picture for this much magnification. And they aren't any heavier or bigger than my 10 X 50's. They came with a nice wide strap and the rubber coating has enough friction to keep them from swinging. They sort of "stick" to the front of my shirt. I used them on a camping trip to look at the almost full moon. It was impressive. I could clearly see mountains projecting from the edge as well as the craters of course. They're well made, solid construction. I am very happy with them.

1/26/12 An update since I have used them hunting. They are great for detailed viewing of the antlers for example when I need to decide if it's a legal buck in the Texas country where I hunt. They are clear and sharp and gather light well. Because of the power, it's takes longer to get on target sometimes though the more I used them the easier that got. I do lose depth perception through these very powerful binoculars.
