Tips For Buying Nature-Viewing Binoculars
How to choose the best binoculars to observe nature in your garden and in the countryside.
Many people who want to buy binoculars to observe birds and nature are confused with the many different models read buyers guide and review on this website. There are certainly many fine binoculars on the market that are excellent for observing nature. But what does a good binoculars define to observe birds, animals, butterflies and even reptiles? First of all, there is no better binocular for any purpose. Each binocular model has its pros and cons. Even an impressive front line binocular from Leica or Swarovski has a disadvantage: the price. They are too expensive for some people.
But here are some tips on what to look for in your search for outstanding natural observatory binoculars:
Basic Specifications: First, a brief definition of the basic specification for any binocular, eg. 8 x 40 or 8 by 40, in order. The first number is the magnification of the binoculars. It will make an object appear many times bigger than the naked eye. Then a 8-liter binoculars enlarge a picture 8 times. The second number is the diameter of the largest or "objective" lens in millimeters. This is the lens that meets the image of the object you are viewing. Then a binoculars of 8 by 40 have an objective lens of 40 millimeters. The larger the size of this lens, the larger the binoculars. This can be a factor if you can not carry anything very heavily for hours outside.
Compact size relative to full size: Binoculars with lenses smaller than 30 mm are considered "compact", whereas those with larger lenses are described as "Full Size". In most cases, I recommend people who go with a full size binoculars to observe birds and nature. One reason is that they are much easier to see. One reason for this is that compact binoculars have initial pupils (the smallest lenses you actually look at), which sometimes make it hard to see the whole field of view. Another reason is that full size binoculars are lighter compared to a compact model with equivalent optical quality. This results in sharper and clearer images for the most part. Therefore, look for binoculars in the range of 35 mm to 45 mm. The only time compression may be desirable is when the journey requires transportation of the smallest possible binoculars. Larger lenses (50 mm or more) result in heavier and bulky binoculars that may be harder to transport. But if you do not mind the larger size, these larger lens binoculars can offer very good brightness and ease of use.
Power boost: It can often be a debate among birdwatchers. Most handheld binoculars are in the 7 to 12 power amplification range. The 7 and 8 effects are considered as a general purpose because they generally have a larger field of view, which is the maximum angle that can be used. See a specific model of binocular. This is usually expressed as a number of meters wide, which can be seen at a standard distance from the binoculars (usually 1000 meters). A good range for the field of view is 350 to 400 feet. The higher magnification binoculars (9 to 12) have a relatively lower field of view, a lower range of 300 feet. But if you use them mainly for bird-watching, it's usually not a big problem. Therefore, if you want to use binoculars for a wide range of applications (nature observation, sporting events, landscapes, etc.), a slight increase is fine. If you want to use them primarily to look at birds, a higher magnification binocular will allow you to see more details. In addition to the field of view, another disadvantage of using higher magnification binoculars is that the image will often shake a little more, especially if you have unstable hands.
Close Focus Distance: This is the shortest distance that a given binocular model can clearly focus on an object. In recent years, some optical companies like Eagle Optics have presented some models with very short focus distances, in the order of 5 feet. This may allow you to focus on nearby wildlife such as Butterflies or amphibians. If you want to do it with the binoculars, look for one with a brief focusing distance. Each binocular model is different so you just have to try them.
