Choosing binoculars should be determined on the basis of its destination.Tourist optics is very different from hunting, and military and naval binoculars with high magnification and night vision are included in the category Spetspribor.The quality and the price, respectively, they differ significantly.The main criteria for any of the binoculars are its size and magnification.
Features tourist optics
to hike does not necessarily buy binoculars with a very strong approach.The best option would be 7-10-fold increase.All that is above these figures, it is very difficult for a long time to hold in their hands, so the need to have a tripod.
compact binoculars with a large increase in the 10-fold size is quite suitable for tourism conditions.This can be rubberized model that is much cheaper than waterproof optics.It is important that the device does not take up much space and well "hold" in his hand.If travel is dedicated to the observation of nature, it is preferable to have an easy model with 6-8-fold approach.This is sufficient that the object of observation is clearly visible, but could not get wind of the observer.This category includes companies Celestron binoculars from as low as 3900 p.Levenhuk and with the cost of 5390 p.and higher.
conventional optics is the numbering of the two numbers, for example, 7h35 and 10h50, in which the first digit indicates the ability to approximate the number of times the objects, and the second - the size of the lens in millimeters.
optics for hunting
for different types of hunting, you can choose binoculars with high magnification or an average.The higher the multiplicity, the less charts, so to observe the big game, which can lure to the place, suitable binoculars from 10-15-fold increase.It can be mounted on a tripod and point in the right direction.
If you want a great review to cover part of the forest or the river, it will be the best assistant optics with 4-7-fold approach with a diameter of 25-40 mm lens.An important quality of the optics for hunting - it is impact-resistant and rubberized housing, as well as its weight.It is unlikely that the device will be a help hard by prolonged stalking.A good model is the Nikon Aculon T11 8-24x25 Zoom value 11590 p.
Special hunting optics
For hunters modern industry produces models that were previously available only to the military.This electronic binoculars with high magnification.At their base is a laser rangefinder, which is unique in that it gives to the liquid crystal display information on the exact distance to the subject.This greatly simplifies the possibility of a more accurate aim.They are also an obvious advantage - it shows high-quality images even in very poor visibility or at night.These binoculars with high magnification - reviews and advice on forums dedicated to hunting equipment, confirm this - especially suitable for beginners hunters whose eye has not "zeroed".
Such devices make the error of just one meter, that inexperienced "ranger" greatly simplifies the chance to aim at quality and professional - save at this time.
Marine binoculars
binoculars with high magnification is a good helper for sailors and fishermen.In the open sea is considered to be a major review of the maximum horizon, so there is a choice to be in the middle tier: 7 10-fold approach is enough to get a clear picture of the review.If you need binoculars for the yacht, you can choose a larger increase with the installation of optics on a tripod.
binoculars with high magnification "Nikon" 8h36 or Compass 7x50 CF WP (price 22790 p.) Is quite suitable for sea travel and fishing.All the optics of such a plan is made in waterproof case to protect it from splashes.Prices of marine binoculars are somewhat higher than in the hunting, but the image quality is better.Great demand tactical marine optics.
Tactical binoculars
Binoculars with a large increase in the sea can also be tactical, as they are equipped with distance-measuring grid with a compass that allows you to set a clear picture even with strong pitching.Such optics are not drowning in water, as her body filled with nitrogen.Special lenses with high aperture ratio provide good visibility in clear weather, when there is a glare on the water, and during fog or poor lighting.
Binoculars with a large increase in the sea rather big in size because of their multiplicity, whereas tactical parameters 7x50 binoculars have, making them comfortable and compact.
Many marine binoculars are equipped with auto-focus, which adjusts both eyepieces at the same time, making them much more expensive, but better quality.It is sufficient to make the setting once to all the objects were clearly visible when transferring attention from one to another.
Astronomical binoculars
monitoring of space objects is firmly established in the category of hobbies, so the demand for binoculars with high magnification began to grow.This category does require 10-14-fold approach.The main thing is that the diameter of the exit pupil was 3 to 4 mm.This corresponds to the standard optics performance 10h35, 10x40, 12x40, 12h50, 14h50.
devices from 12h50 to 30h90 considered specialized, have a narrow review, but give a clear vision of the parts in space, for example, Celestron Cometron 12x70 worth 7490 p.Astronomical optics has moved beyond the telescope, so today no surprise concept of "binoculars for astronomical observations," even though the prices are quite high.Binoculars with a large increase in large, so a tripod is necessary.
Optics produced in the USSR
During the Soviet era standards for military optics were considered the highest in the world.Optical-mechanical plant for its production, such as Zagorski (B8h30 USSR ZOMZ price of 12 000 rub.), Salavat (B10h50 SOMZ 13 500 rub.), Kazan ("Photon" -7BKFTS 7h35 KOMZ of 11 000 p.) famousits products, some of which were exported to foreign countries.
All binoculars with high magnification (USSR produced a lot of them) are still in demand, as the price they are lower than modern optics, but it can meet even the highest demands.They differ in purpose: for example, the military field and marine binoculars have a net and resolution up to 20x60 mm.
Optics for hunters and tourists easier, but is consistent with its use.Thus, light and small size binoculars series "Photon" were popular not only among fans of hiking, fishing or hunting, but also for the Coast Guard.Resolution 7h35 mm multi-coated lenses and a robust housing allows their use in extreme conditions, in bad weather and at dusk.
optics with very high magnification
binoculars with a magnification of 100 times have range of applications in astronomical observations, or for animals and birds.Its characteristics are close to the telescopes, so require installation on a tripod.
Binoculars Russian production
Russian optomechanical manufacturing producing binoculars for military purposes as well as for mass use.Zagorsk plant, for example, are made not only electronic and usually approximates the optics, but also a polarizing film and color filters, which are used for all types of spectrum.Among the large variety of the plant, you can pick out the optics with a range of 15-fold approach.Scope of application - it is astronomical observation, tourism activities, sea travel, watching animals and birds.
Binoculars with a large increase in Russian production, which are used at night, produced at the plant "Jupiter".These devices are suitable for use in the dark for observing distant, and for close objects.Specialized equipment produced in Russia, for example, binoculars "Farvizhn" BCS M 20x50 with stabilization are 99 900 p., While conventional optics can be purchased from 1500 p.
most important technical characteristics of binoculars
approximating to choose the right optics, should focus on the basic parameters that affect the quality, price and its scope.
- considered the most important indication of multiplicity.The best and most popular are binoculars with a magnification of 6-10 fold.Anything above already requires extra effort and skills to use, or installation on a tripod.Increased facilities from 6 to 10 times - it is quite enough for the application of such optics in hiking, hunting and fishing, by observing the animals.Binoculars with a large increase is not always the best choice if you want an easy assistant in the campaign.
- Next in importance is the diameter of the lens: the higher it is, the clearer and clearer the picture.This is because a larger lens collects more light, making distant objects bright and dim.For binoculars considered sufficient ground surveillance records from 30 to 50 mm.If a more powerful optics, e.g., astronomical observations, it can reach a diameter of 50 to 80 mm and even above.Optimal ground binoculars has parameters 7h35, 7h42, 8x40, and at 10h50 indicators for long-term monitoring has required a tripod.
Based on these data, you can choose the optics in their preferences, but there are indicators that affect its quality and price.
Focus centered
More expensive binoculars have an autofocus, a special mesh or a laser rangefinder.Electronic rangefinder optics is the most expensive segment of the market.These are precision instruments with a quick adjustment at the same time the two eyepieces.
Manual focusing is made by myself, and if equipped with binoculars has a diopter adjustment, it can be made even for those with nearsightedness and farsightedness.The new generation of fixed focus optics provide for those cases where there is no time to engage the setting.Such devices are used firefighters, rescue workers, hunters, pursuing prey.
angle of view and exit pupil diameter
These settings also affect the price of binoculars and field of application.
- Angle refers to the distance that covers the human eye through binoculars.The higher the multiplicity, the less one sees the review.Optics with a very high approach, with indicators such as 30 and above, requires a certain orientation of the object.While shorter-range gives a broad overview, which allows you to use them on the water, and in the field, or the mountains.This type of binoculars called widespread.To determine this index manufacturers specify the width of the field of vision, in meters, e.g., 110/1000 m, which means a review of 110 m at a distance of 1,000 meters of the object.
- best indicator of the diameter of the exit pupil is considered to be an indicator close to the size of the pupil of the human, that is, the day is 2-3 mm, and in the dark 6-8 mm.Therefore, the data are considered to be generally accepted standard of 5-7 mm.To determine the diameter of the exit pupil, the size of the lens must be divided into its fold.For example, a pair of binoculars with an index 7h35 has an exit pupil of 5 mm (35: 7 = 5).At higher light performance is not fully accepted by the human eye, and accordingly, the visibility will be worse.
Binoculars are also distributed by the fact of what made lenses.They may be lens and prism.The former refers theatrical optics, to the second - all field devices.
prism optics is divided into two systems:
- Porro, in honor of the optics of France, in which the lens and the lens distributed by successive steps, which expands the perspective of view and gives a clear picture.
- Roof System - a prism with two faces, arranged at an angle to each other.Such optics more compact and lightweight, but expensive due to the complexity of the grinding and polishing of prisms.
Therefore, before you commit to a choice of binoculars, you should select a few starting points for orientation in a large assortment of goods:
- purpose binoculars;
- focused review or widespread;
- multiplicity approach;
- kind of focus;
- country of origin and brand name;
- approximate price.
giving an answer on these points, it is easier to make a purchase that will not bring disappointment and frustration.
