The characteristics of hunting binoculars

In order not to get lost in the immense world of binoculars, it is good to have clear those key concepts, which allow you to juggle the long technical sheets that are submitted to us as they were the answer to all of our, when instead the risk is that they confuse ideas even more.

First of all the magnification, because beyond boasting of having more or less powerful binoculars, it must always be taken into account that bigger is the magnification, smaller is the field of view, that is the portion of the field framed.

We must start from the assumption that the binoculars on the market are designed for the most varied uses ranging from bird watching, to travel, to theater or sporting events; in practice, each use requires its own characteristics and therefore identifying the ideal parameters for a hunting use is important in order not to make easy mistakes.

The size of the objective lens diameter

So let’s start from that figure that we find on the 8×40, 7×50, etc. instrument.

What do they mean? The first number shows the magnification that the binoculars provide while the second number shows the diameter of the objective: larger is the objective, brighter the binoculars will be and the vision bright and detailed.

Therefore, increasing the magnification reduces the observation brightness. A 7×50 model will therefore be brighter than a 20×50 model even if the lens diameter is the same.

For hunting, it is better not to go below 8 magnification because you need to keep a certain distance from what you observe. To give a very understandable example: if I have binoculars that magnify 8 times, I will see the animal as I would see it with the naked eye being 8 times closer to it.

There is also another useful parameter that can be calculated to get an idea of the viewing expectations with the instrument to be purchased: binoculars with 10x magnification will make an object 100 meters away appear instead as if it were only 10 meters (100 : 10 = 10).

The high magnifications are suitable for stationary targets, possibly using tripods or supports. The 8-10 magnification is the ideal solution for wooded areas, when shooting at medium or low range and at moving targets.

Regarding the choice of the diameter of the objective lenses, normally the ideal diameter is 42 mm, but if you need to have contrasted images at dusk or in situations of uncertain brightness, it will be necessary to go up to 50-52 mm in diameter. , to ensure more light inside the lenses.

The lines of Konus hunting binoculars

Among Konus binoculars there are various lines designed for hunting and which meet the needs that this passion imposes.

Konusrex binoculars

Clearly there is also the budget to determine the choice, but if you want to opt for the top of the range, certainly the choice will fall among the models of the Konusrex line, which covers the four most requested sizes on the market: 8×42-10×42-10×50-10×52 .

To make Konusrex binoculars the flagships of the Konus range is the treatment of the lenses, so it is good to clarify the various existing treatments as we often see binoculars with red lenses, green lenses, blue lenses and we do not understand the difference when instead it is precisely on lenses and prisms that most of the qualitative differences “play”.

The surfaces of the lenses, both internally and externally, are coated with special optical treatments in order to facilitate the transmission of light for the benefit of image quality and brilliance.

Titanium and Konusarmy binoculars

We can find binoculars with the wording COATED which means that a single treatment has been carried out on a single surface of the lens, FULLY COATED means that a single treatment has been carried out on all the surfaces of the lens, MULTI-COATED indicates that a single treatment has been carried out multi-layer treatment on a single surface of the lens (as for the Titanium and Konusarmy lines) and finally FULLY MULTI COATED indicates that the multi-layer treatment has been done on all surfaces of the lens (as for Konusrex binoculars).

There are models with special treatments recognizable by a different color of the objective lenses: for example when we see binoculars with red lenses (“ruby coating” as in the entry level lines of the Konus assortment) or green (“dark green coating” as in most part of Konus binoculars) we understand that these binoculars also lend themselves to difficult observing conditions as this “layer” has been created to allow them to filter the light in order to obtain a clear vision.

Emperor binoculars

The added value of the Emperor line is given by the phase correction, that is the binoculars with roof prism construction inevitably give rise to an optical aberration to the detriment of the image resolution (which would be those of the compact and modern line).

This problem in the Emperor line is overcome thanks to a special coating of the surface of the prisms, which allows to obtain the maximum resolution and the best contrast.

In the Konusrex line, on the other hand, we see the silver treatment technique, which covers the internal prisms of the instrument with a very reflective system, that is a very thin layer of silver-colored material is applied to all the prisms with the result of obtaining an incredible optical performance with a light transmission value of as much as 98%.

These are the essential data but shortly we will deepen other aspects that will allow you to become familiar with other terms such as interpupillary distance or focus. Soon!
