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(r x tan ω) = 2 x tan(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. 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.

    • Overall excellent quality, BUT with some cut corners and deception from Nikon
Style: Nikon Action 7x35 EX Extreme ATB Binocular
Review Image by S. L. Van Scoyoc S. L. Van Scoyoc

I use my binoculars almost exclusively for hunting, scouting, and navigation aboard my yacht. I compared these Nikon 7X35s with: Tasco 7X35 wide angles from 1978; Pursuit 8X42 roof prisms from 2015; and Binolyt 7X50 marine binoculars from 2005. With 50mm optics the Binolyts, which exceed the Nikons in build and quality, are an unfair comparison and they are quite heavy to carry around the forest. The Pursuit binoculars are quite good for the money, but as roof prisms are not optically up to either the Nikon or the 45 year old Tascos. Nor are they particularly light, weighing in the same as the Nikon and only slightly less than the vintage Tascos. The most important thing of note is that while all three of my other binoculars share one thing in common -- excellent blackening within the tubes with everything treated to be anti-reflective. The Nikons, viewed head on, look like the front end of a '59 Cadillac. Shiny metal and no effort to treat tubes and mounts with anti-reflective coatings. It didn't take long on forums to find that other users are noticing glare under some circumstance -- typically on the beach and watching birds. I contacted Nikon about this who first told me they don't claim the interior to be blackened. When I sent photos of the box which clearly shows the claim they came back to me suggesting that I send them in under warranty for "service". The box states: "Internal blackening minimizes light loss inside binocular tubes." This is not true. The cutaway illustration on the box also shows the blackening on the interior. Many other references on the web offer this quality as a selling point. As the cost of shipping these to Nikon would simply add more cost to the Nikons and leave me with optics that have been disassembled, never a good idea on something only a couple of weeks old, I have declined and decided to keep them as "cheap" glasses. While the Nikons do have many fine qualities, it might be worthwhile considering Bushnell or another no-name brand as this is already the low end of the market, but which may be equal and less-espensive. In a direct comparison, as you can see by the photos, the Nikon and the Tascos are nearly the same size and shape. Lenses are the same size. They are comfortable in the hands and settle there like they are meant to be there. They are essentially identical in weight. The lens multi-coating, unless modern coatings are invisible, seems minimal but I'm sure it is just progress and that it does its job well. However, as Nikon does not openly state "fully multi-coated" which is the best, opting to say "multi-coated" which means only that some lenses are multi-coated. The good -- eye relief on the Nikons is generous so no need to remove glasses to use them. To that end, the eye cups twist down and are held securely by detents -- they are better than any I've seen on lower cost glasses. The Tasco has virtually no eye relief and, although usable wearing glasses (due to an already wide angle of view), the Nikon is better and very nice in this regard. The eye cups are unlikely to shift in use or during carry. Likewise, the diopter is well secured and unlikely to shift in use. The glasses are rubber coated and waterproof/fogproof, which is a huge advantage over the Tasco although in 45 years of use I never experienced problems using them outside and when not in use kept them in a ziploc bag with desiccant. Optically, they are on a par with the Tasco, which is to say they are quite good. The caveat here is that while the Tascos are sharp across the entire field-of-view, the Nikons are sharp only in the centre and there is noticeable blur in some of the peripheral areas. Not a problem but does interfere with how some of us scan an area panel by panel. Narrower angle of view, but still wider than most. The not-quite-as-good -- Focussing is stiff and slow due, no doubt, to the o-rings that make it waterproof. An acceptable compromise. It is precise without sloppiness. The Tasco is faster. The aforementioned lack of black-out inside the barrels is a concern. The caps for the lenses, particularly the objectives, are very poor and will be lost or lose their resilience in pretty short order. The strap is the typical cheapie but better than the narrow piece of plastic the Tasco came with. A decent camera strap will fit and should be ordered at the same time. Overall, they are good for the purpose. Porro-prisms in a 7X35 are quite compact and light while offering vastly superior viewing, including enhanced depth perception, to roof prisms in the under $500 category. For something that will be expected to go everywhere in the forest, ride in the back of a truck, and so on, these are very good and compared to many, superior. I will say that I'm certain these will become the one pair I use for nearly everything and, at my age, will be the last pair I need to buy. I recommend these for anyone who needs good optics, reasonable weight and size, and is spending money to acquire a reliable product and not to impress the rest of the world. These will do the job you need and with a little care may be the only pair you ever buy. Bear in mind, however, these are "cheap" binoculars where Nikon has cut corners to maximise profit rather than benefit the customer. Be sure to consider all options before paying extra for these. ... show more

    • Field of View
Style: Nikon Action 7x35 EX Extreme ATB Binocular
These binoculars are all about quality in the largest field of view. If you want to see a wide expanse of nature or the heavens downrange from your position, these are the way to go. I got them specifically to frame smaller constellations and asterisms, the detail of which can be further examined with a scope. They help tremendously to put the object in the scope into context. Ordinarily, observing half a degree of field tends to abstract objects almost entirely from their surrounding. Since it's not practical to really "zoom" in using a single optical instrument, using these in combination with something of higher power is ideal. Don't get me wrong, I do have a zoom on the scope... it zooms from 25x to 50x -- amazing but you have to understand that this is a field of view of 2.4 to 1.5 degrees -- essentially like looking through a pipe to a drinkstraw. These Nikons however, show over 9 degrees field of view -- something which is unsurpassed in the highest-end binocular out there. There are compromises necessitated by the optical principles used to make these function. They do not have a very flat field of view, meaning objects in the center of the field (circle) can be focused, but objects nearer the edge of the field are out of focus. This is because the focused field is curved not flat. This problem is also evident in most 10x50's for example. It's less of a problem in good quality 8x42's like Nikon's Monarch for example, and obviously the high end Swarovski, Leica, Zeiss etc. This problem matters more when you have a narrow field and highly magnified image where the subject tends to fill the field of view. It matters less when the subject is focused in the center of the field and the background surrounding it is slightly out of focus. Still, even if you pay the biggest bucks for bright, flat, and sharp images from the top of the line binoculars, you'll still only see about 8 degrees true field of view, whereas these give you over 9 degrees. Furthermore, they give an apparent field of view of over 59 degrees, rivaling the top-of-the-line binoculars. If you're looking for a handy, all-purpose binocular, the roof-prism 8x42's are proven to be far more popular for a number of good reasons (more compact, more magnification while not yet needing a tripod or IS like 10x does, more competition and choices etc.) But if you're looking for the best field of view with high quality optics, this is it, and fortunately it comes at a very reasonable cost. I don't know what other 7x35's are out there, but I can tell you this is far better than Celestron or Bushnell. ... show more

Style: Nikon Action 7x35 EX Extreme ATB Binocular
Read about this particular pair on a birding blog. Birds are most active in the early morning when there may not be much light. These binoculars are designed to maximize letting light in and have enabled me to see plumage much much better. These binoculars are much lighter than my previous pair, but in their class, they are not the lightest, so my hand does get a little sore after a couple of hours. My birding skills have increased a great deal: better at tracking, quicker at spotting. I love these binoculars. ... show more
