Whilst not at the same level as which you get from a high or even mid-to-high level 42mm binocular for example, for a low costing 25mm compact binocular, I thought that the colors produced and the level of contrast you see in the image were pretty good. this is especially true at lower magnifications where I am happy to say they easily compare with the majority of other 8x or 10x compacts that I come across at this sort of price level. As the simple eyecups are not really adjustable, there is not a lot you can do other than for them completely down or use them at the maximum setting.

This is mostly down to the fact that I generally advise most people against getting a pair of "zoom binoculars" because whilst they may seem like a great idea, in reality it has been my experience that they often turn out to be disappointing and the downsides usually outweigh the advantage of being able to zoom into a view.
To minimize reflection on the lens surfaces and ensure clear, sharp images, anti-reflective coatings are often applied. These anti-reflection coatings are very important as part of the light that passes through any lens is reflected by the front (incident light) and rear (exiting light) surfaces. This reduces the amount of light passing through the lens and if this transmittance is very bad, the image you see will be darker than on binoculars that transmit more light. Also, the reflected light may cause ghosting and flaring, affecting image contrast. The lenses on these Nikon EagleView Zooms are multilayer-coated. What this means is that they have received multiple layers of anti-reflective coatings which helps to increase light transmission, for a brighter image and therefore better low light performance. This is good, but it would have been even better if they had been fully-multi coated, which would mean that they had multiple layers of anti-reflective coatings on all air to glass surfaces and not just some of them as these are.

Below is a table comparing this Nikon EagleView Zoom with a selection of other compact binoculars. The very top of the range Swarovski 8x20B compact binoculars as well as a few others like the Pentax 9x28 DCF, Minox 10x25 BV BRW's, Kowa 8x25 BD and the Steiner 8.5x26 Wildlife Pro. Also included within the box is some basic and generic instructions that covers the entire Discovery Gator series. Also included is the international warranty card that covers these binoculars for 2 years and entitles you to free repair or replacement in any country where a Levenhuk office is located.These EagleView Zooms come with a fairly disappointing 13mm of eye-relief, which may be something to keep in mind if you want to use your optics whilst wearing glasses. Ideally and to be sure that you have enough distance to play with to enable you to see the full field of view without any vignetting when using your glasses most experts recommend that you should look for binoculars that have an eye relief of about 16mm or more. In most cases an eye relief of 14 to 15mm is adequate for most people who wear eyeglasses to be comfortable, so 13mm is a little on the short side. Most non-eyeglass wearers will just use the eyecups in the fully extended position. An inch (symbol: in) is a unit of length. It is defined as 1⁄12 of a foot, also is 1⁄36 of a yard. Though traditional standards for the exact length of an inch have varied, it is equal to exactly 25.4 mm. The inch is a popularly used customary unit of length in the United States, Canada, and the United Kingdom. Centimeters to inches formula and conversion factor
Some cheap optics use coatings on the lenses to artificially tint the view, for example you find many cheap binoculars with ruby coated lenses which are used to filter red to compensate for their poor-quality optics that do not properly converge the color spectrum. Thankfully this is not the case with these and I thought that the colors that are produced by the EagleView look and feel natural, but with possibly a tiny bit less saturation than on my control binoculars. The minimum focus distance on these is advertised at 5 meters, which is not good. However, I measured it to just over 3 meters (10ft) on my set, which is a lot better, but still falls far short of the best and thus would not suggest these as the ideal choice if you were looking for a bino especially to view things like butterflies or other objects from closer distances. If this is the case this section on close focusing binoculars should help. I do still have some reservations as to combining a compact instrument with small 25mm lenses and a powerful 20x magnification as it really does reduce their optimal operating window and they are never going to be able to offer you the image quality or brightness of a high powered fixed magnification binocular with large lenses. Comparing the view through these and that of my control compact, at 8x magnification I would say that in terms of brightness, they were almost equal, which is pretty good and equal to many much more expensive binoculars in this class. As you adjust the zoom and increase the magnification, you can actually see the image produced getting darker and darker, which is to be expected (see exit pupil above). In poor lighting conditions like at sunset, this actually has quite a big impact on just how effective and useful these zoom binoculars are. It may be obvious, but it is for this reason and the fact that they have such a small field of view that you really should not consider these Nikons as an option for binoculars for astronomy.With these Nikon binoculars, the minimum distance that you can focus on an object is a 4 meters (13.1ft) away, which once again is not great and quite a bit further than the best. I consider anything under 6ft to be very good. So if you are looking for a compact binocular specifically for things like observing butterflies then I do not recommend getting these. Rather take a look at these close focusing binoculars.
At 12x Magnification:When you increase the magnification on these Eagleviews to 12x their Exit Pupil reduces to 2.08 (25/12) which means that less gets to your eyes.As you decrease the power, this widens to a maximum of 4.6° (80m @ 1000 meters / 240ft @ 1000 yards) at 8x power, which has to be said is pretty narrow if you compare them to an average 8x binocular. Made from a very fine woven nylon type of fabric, the included soft case is pretty basic, but functional: This is why I would suggest trying to mount your binocular onto a steady base like a tripod if you are going to use any magnification above 12x to 15x. Thus I feel it is a shame that these binoculars are not easily tripod mountable using a standard binocular tripod adapter and thus to do so you will have to think a little outside the box and come up with your own plan or at the very least try and rest your elbows on a steady surface like a table.
At the low 8x zoom setting, I did find that there was just enough eye-relief to use them whilst wearing glasses and get the full field of view.

However, having said that, if ultimate image quality and brightness at a high magnification is not that important to you and you are only looking to be able to identify something at long distance and you need a small lightweight device these most certainly could work for you. Most binoculars have a diopter so that you can calibrate them to allow for any differences in the vision of your left and right eyes.I also really think the Gator is a fun little compact binocular to play around with and thus another definite use could be as a set of binoculars for older children to use. Now usually I recommend get a low powered binocular for kids as it makes them much easier to use. But with a zoom binocular like these, they can start off at the low 8x setting and then zoom into objects which I know for certain most if not all kids will love! Ideal Uses: Like most compact binoculars, these are pretty good if you are looking for a take anywhere pair of binoculars, perfect for camping... although not if you are going to get them wet! I would take them hiking with me, if spotting birds and wildlife was not my main focus as they are let down by their poor field of view. I also see them sitting in the cubbyhole of my car, or in my golf or kit bag to be used at any time. I think where they may be ideal is at a sporting event, where you can use the zoom to take in some details on the field, although once again a wider field of view would have really been appreciated here.
