GMGold Black Wooden Picture Frame, Wood, Lot de 1 NOIR, 10x15 cm

Product Information

But other than these minor points, I would say that as you would expect of any Nikon product, they look pretty well made and considering that they have a plastic shell, they still feel fairly solid and robust and in terms of build quality are as good as any compact porro prisms found in this price range. 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. 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. You must be available to accept delivery on the date you have requested, failure to do so will result in paying for a re delivery charge.

Another downside to them not being fully covered in rubber is that there is more chance of them making a louder sound if something like your watch or more commonly a ring on your finger strikes against them. Rubber armour dampens down the sound and helps to ensure that you don't frighten away easily spooked animals like birds or deer. Whilst there is no mention as the actual material used in the construction of the chassis, I think it is safe to assume that a polycarbonate plastic is used when you considering their price and just how lightweight they are. Whilst this may not be quite as luxurious or as strong as more expensive materials like magnesium or aluminium, these Discover binoculars don't feel particularly flimsy in any way.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. 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. 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.

Located near the right eyepiece where you usually find the diopter adjuster is a slider which is used to alter the magnification. I found the placement to be excellent as it was very easy to change the magnification setting using my right thumb without having to move the binocular from my eyes or make a large change to my natural grip on the binoculars. This IPD (Inter-Pupillary Distance) range is very good and therefore they should be able to accommodate a wider range of faces than many, including those with closer set eyes like children and thus in this area and the fact that they are small and lightweight, it makes them a good choice of binocular for kids. The centimeter (symbol: cm) is a unit of length in the metric system. It is also the base unit in the centimeter-gram-second system of units. The centimeter practical unit of length for many everyday measurements. A centimeter is equal to 0.01 (or 1E-2) meter. Definition of inch At 8x Magnification: All binoculars with an 8x magnification and 25mm objective lenses have an Exit Pupil of 3.13 (25/8) and a Twilight Factor of 14.1, which if you compare them to a full size 8x42 binocular, which has an exit pupil of 5.25 and a twilight factor of 18.3, it shows that the increased objective lens diameter of the 8x42 binoculars will gather more light and make it possible for the binoculars to transmit more light to your eyes. This is the main compromise to using a compact over a larger pair of optics, but having said that in reasonably good lighting conditions like during the day, where your eye pupil size is only about 2 to 3mm, this will not be much of a factor, it is just at twilight and under poor light where you can really notice the difference. You must also remember that having a good pair of compacts even in poor light is still much better than having no binoculars at all!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. When set to a magnification level of 8x, their field of view is 80m at 100m / 240ft at 1000 yards (4.6°) - which, for a what at this setting effectively an 8x25 binocular is not very good. To put this into context, the Steiner 8.5x26 Wildlife Pro has a FOV of 333ft at 1000 yards and the Kowa 8x25 BD has a FOV of 331ft at 1000 yards and even the Minox 10x25 BV BRW which has a magnification of 10x has a FOV of 290ft at 1000 yards.
