I sit high, I look far away! Five versatile binoculars

Celestron UpClose 8x40 Auto Focus

The engineers of the American optical company Celestron built their brainchild without using a focus system in its design. This function is given directly to the human eye and is carried out due to accommodation - the adaptation of vision to the objects under consideration at different distances.

The world through the eyepieces of the binoculars looks clear and sharp without the influence of parasitic effects (such as chromatic aberration) on the image. Inverting prisms of the Perro type have a large diameter, which provides a large field of view of the binoculars - at a distance of 1 km, it captures in its lenses the area, the largest distance between two points of which is 139 m.

The binoculars are made in a minimalist style. To get started, just bring it to your eyes and adjust the eyepieces for yourself, spreading them to the required distance. For those who have poor eyesight, diopter correction is provided in the range of ± 5 D. The body of the optical device is distinguished by excellent ergonomics, secure grip in the hands and the presence of a tripod mount. In addition, it is dust and moisture resistant.

The lenses of the binoculars do not have any antireflection coating, therefore, despite the large diameter of the exit pupil, the image in low light conditions does not shine with high detail. When using binoculars of this type, it should also be taken into account that the eyes are subject to increased stress. In order to minimize it, it is not recommended to use the device for long-term observations. But for a short look at active sporting events or at wild animals and birds, binoculars are the best fit, which is facilitated by excellent sharpness throughout the field of view.

Celestron UpClose 8x40 AutoFocus, among other things, is appreciated among tourists. Especially those who are prone to outdoor activities. It will help you quickly assess the situation around, quickly find a place to sleep or see which way this or that path will lead.

BRESSER Hunter 7x50

The products of the optical company BRESSER once again confirm the vaunted German quality - binoculars with the Hunter 7x50 model index are excellent proof of this.

The diameter of the front lenses of the binoculars is 50 mm, which, together with a blue anti-reflective coating, gives a clear and crisp image under a wide variety of viewing conditions - whether it is a sunny day or twilight dawn. Porro type prisms are made of high quality VK-7 glass and enclosed in a robust case that protects the optical elements from splashes. However this does not mean that binoculars can be used in heavy rain.

At a distance of 1 km to the object of observation, the field of view of the binoculars is 112 m. At the same time, it provides accurate visibility of details and high image contrast. The 7x magnification virtually eliminates the possibility of shaking in the image, but if you use the optical device for a long time, you may experience hand fatigue. This shortcoming can be easily corrected by mounting the binoculars on a tripod.

It is not for nothing that binoculars bear the prefix “Hunter” in their name - they are suitable for observing prey and the situation around. In addition, fishermen and tourists pay attention to it. Excellent image quality and fast optics are its strong points, which are complemented by an attractive price.

Reference. The aperture of binoculars is determined by the diameter of its front lens. This value always appears in the name of the model along with the magnification factor. The larger the diameter of the lens, the more light it can absorb, making the binoculars more effective when used in low light conditions.

Nikon Aculon A211 8-18x42

The eminent Japanese manufacturer of photographic equipment Nikon feels very well in the field of optical devices. Therefore, it is not surprising that his binoculars are highly valued among amateurs and professionals alike.

As the name implies, the universal model Nikon Aculon A211 8-18x42 boasts an adjustable magnification factor (from 8x to 18x). Changing the diameter of the exit pupil is carried out using a lever mechanism located on the upper face of the housing. When zooming, this indicator can vary from 5.25 mm to 2.3 mm. Accordingly, with an increase in the magnification of the approximation, the angle of the field of view and the aperture ratio will decrease.

At minimum magnification, the binoculars provide a field of view of 80 m (at a distance of 1 km to the object of observation). Due to the high twilight factor, which is 18.3, as well as the presence of elements with a multilayer antireflection coating in the design of the binoculars, the optical device forms a clear and detailed image in low light conditions. However the large diameter of the lenses affects the overall weight and dimensions of the binoculars - it weighs 825 g and takes up quite a bit of space.

Most often, tourists, hunters and nature lovers pay attention to binoculars. They can observe objects of interest from a distance of 13 m without worrying much about possible mechanical damage - the body of the optical device is shockproof. It also features a 1/4" tripod mount and a diopter adjustment on the right eyepiece for those with imperfect vision.

Olympus 10-30x25 Zoom PC I

Long-range binoculars with variable magnification from the eminent Japanese brand Olympus allow you to see objects of interest up to 30x.

The optical scheme of the binoculars has 9 elements in 6 groups, which are enclosed in a compact and stylish plastic case with rubberized inserts for a more confident grip. The design of the binoculars uses lenses with a special multi-layer coating that prevents the penetration of ultraviolet radiation. This makes it possible to use an optical device on a bright sunny day without fear of harming your eyes. In poor lighting conditions, you should not count on excellent detailing - the relative brightness parameter of binoculars does not shine with outstanding results.

The device is able to focus on the object under consideration from a distance of 5 m. The maximum value of the field of view at a distance of 1 km ranges from 56 to 33 m (depending on the selected magnification factor). It should also be taken into account that due to the presence of moving elements in the optical scheme, the field of view of the device is somewhat reduced in comparison with binoculars with a fixed zoom.

At the lowest magnification, there are absolutely no questions to the picture in the eyepieces of binoculars. But at a 25-30-fold approximation, the image begins to darken, which is due to the low aperture ratio of the optics. In addition, trembling appears and in order to stabilize the picture, you have to look for a fulcrum, because. There is no tripod socket in the design of the binoculars.

The number of advantages outweighs the bowl with an insignificant number of minuses in its favor. Real owners of binoculars praise it for its high zoom ratio, the ability to observe dynamic and static scenes with glasses, and also for its high quality workmanship.

Canon 8x25 IS

The pride of the binoculars from Canon is the optical image stabilization system, which effectively compensates for hand shake during observation of the objects in question.

The stabilizer is a special prism that, when vibration is detected, deflects the light beam in the right direction in a fraction of a second, thus providing a clear picture. Physically, it is located directly between the lens group and the Porro prism, and the stub activation button is located on the top of the binocular body. The stabilizer is powered by one CR123A battery, the charge of which lasts for 5-6 hours of use (depending on the ambient temperature).

The optical design of the device includes lenses for leveling the image field. These elements are designed to combat distortion and curvature of the field, which at a distance of 1 km to the object of observation has a diameter of about 115 m. In simple words, the lenses allow you to see the surrounding space in its natural form.

To minimize the appearance of glare and stray light, the optical elements of the binoculars are coated with a special coating called Super Spectra. Its parallel function is to increase the contrast of the image and provide natural colour reproduction, with which binoculars have no problems at all.

Among models with a stabilizer on board, the Canon 8x25 IS is the lightest and most affordable representative. With it, you can completely forget about a tripod, admiring a clear picture in far-off eyepieces from a minimum focus distance of 3.5 m. The only thing that needs to be done for effective operation of the device is the timely replacement of batteries.
