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

Product Information

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 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 350g (12.3oz), it must be said they are on the heavy end of the scale when compared to most other compacts, they do however still feel very light compared to most standard full sized 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. Other than to say that the objectives have a 25mm diameter and that the oculars are just over 12mm in diameter, I can't really expand as no information is given.

The focusing mechanism is geared so that it takes a full 2 and 1/4 turns to go from infinity to it's minimum focusing distance of 13.1ft (4m).What this means is that focusing from near to far (or vise versa) takes a little longer than ones that take less turns, but it does have the slight advantage of making fine tuning your focus just that bit easier and more accurate. I think Nikon have got this about right with these as it really helps you to get the correct focus when you have the magnification at the higher settings like it's maximum of 24x. 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, in low light conditions when the pupils in your eyes are more dilated, this drop off in perceived image brightness becomes far more evident as the small exit pupils make it impossible for the binocular to supply your eyes with enough light for you se perceive a bright image. This is completely understandable and to be expected and so having said this, on the whole and when comparing them at the equivalent magnification, these for me compare well to other 8x or 10x compacts at this level which is good.An important thing to consider when looking at the size of a compact binocular is how small they are when they are folded. When you are are looking through them, just how small they are is not that important, but size is far more important when you carrying them around with you. Different designs of compacts fold up in different ways and this can make a big difference is their size.

Weak points? Their very narrow field of view, even at 8x magnification is really noticeable and their rather distant minimum focusing distance are definite weak points. The amount of eye-relief will also be disappointing to those of you who want to use them with glasses on. The fact that they are neither water or fogproof is also a shame, especially for those that like to use their optics in all weather conditions. You must remember that as well as the Exit Pupil, the performance of a pair of optics in poor light also depends a lot on the quality of the glass and optical coatings and not just the exit pupil and twilight factor formula. Good coatings on the lenses and the prisms can double the amount of light that gets through the binocular, when compared to those that have none or poor quality coatings. Weight and especially size really matter in a good pair of compacts and obviously we are looking for a pair that is as small and lightweight as possible. This is because if the "compact" pair is too large to suit your specific requirements, you may as well just go and get yourself a similar quality mid or full sized pair of optics that by their very design will usually perform better, especially in low light conditions: To calculate a centimeter value to the corresponding value in inches, just multiply the quantity in centimeters by 0.393701 (the conversion factor). Centimeters to inches formulae At 24x Magnification:When you increased to their maximum level of 24x the Exit Pupil reduces to just over 1 (25/24) which means that not a lot of light that enters the binocular will reach your eyes.Image shake dramatically increases at the higher magnification, which makes it very hard to view fine details, which in many ways can negate any advantage you get from viewing an object at a high magnification. 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. This Nikon compact has, what I think are actually two hinges (it is hard to see as they are located under a cover), with both hinges located very close to each other, meaning that they almost work like single a central hinge design. Whatever the case, the two barrels can be brought closer together or pulled further apart to match the distance between your eyes ( Inter-Pupillary Adjustment) by opening or closing the hinges. This adjustment felt smooth and there was the right amount of friction to prevent them from opening or closing too easily, but not too much so as to make moving them difficult. The minimum distance between the centers of the two eye-piece lenses that can be achieved is 56mm when fully folded and the maximum is 72mm when full opened.
