A quick glance at the binoculars market will make us realize the great variety of different models we have at our disposal, which undoubtedly complicates the choice.
Therefore, we are going to explain below the variables that you should take into account when buying binoculars, so that you can be sure that you are making the right purchase:
- THE MAGNIFICENCE: this refers to the apparent magnification of an object seen through the binoculars, compared to observation without them. Thus with a magnification of 7, an object located at 700 m. appears to be at 100 m.
The ideal magnification is between 7 and 9, since less than 7 is insufficient magnification for outdoor use, while more than 10 increases the movements too much, causing a certain instability in the image so that this type of binoculars are not suitable for use at sea (although they are widely used on land) - OPTICAL DIAMETER: this is the diameter of the objective lens expressed in millimeters, so that the larger the diameter, the brighter the image will appear.
(Para a comfortable use on board a boat), the diameter considered optimal is 50 mm - FIELD OF VISION: defines the width of the observed area at a distance of 1000 m (indicated in meters or degrees).
The higher the magnification, the smaller the field of view - PUPILLAR DIAMETER: corresponds to the small ring that we will observe inside the eyepiece of the binocular. If the pupil diameter is large, it will positively influence the brightness of the image.
Para for use at sea, it is best to choose a binocular with a pupil diameter of 7mm, which is the maximum diameter of the pupil of the eye in night vision, so that there will be no loss of brightness in bad conditions - LENS TREATMENT: untreated lenses lose about 30% of the light received, which undoubtedly affects the brightness and sharpness of the contours of the objects observed.
Lens coatings reduce the loss of brightness while improving colors and filtering out part of the light U.V.
MULTI: special additional coating on certain lenses. Additional advantage: less distortion of colors and/or filtering of U.V. - PRISMS: two types:
- BAK-7: borosilicate prism
- BAK-4: baryum prism. Higher quality glass than BAK-7. They have a wider repair index and allow more light to pass through with less distortion of brightness
Before buying binoculars, we must be aware of the use we are going to give them as well as the budget we will have available in the choice when determining the technical characteristics we will choose.
A. TYPES OF PRISMATICS
Depending on the internal structure of each binocular (objective lenses, eyepieces and prism system).
- Depending on the prism system, there are two types:
- Porro: with better depth perception and the most economical option.
- Roof: with a smaller and lighter body.
- According to the quality of the prisms:
- Organic: they are usually made of plastic and are of poor quality.
- Mineral: or glass, they are the best option and can be BAK-7, cheaper and lower quality borosilicate glass or BAK-4 of higher quality and with sharper images with barium glass.
- Depending on the lens treatment:
- Coated: Partial coating
- Fully Coated: Complete coating
- Multicoated: Multiple layers of coating
- Fully Multicoated: Several layers of full coating
- Magnification and aperture:
The magnification is determined by the first technical number of the binocular optics, and the aperture by the second number (e.g. 8x40). In general, amateur binoculars should have between 7 and 10x magnification. Likewise, the larger the aperture, the higher the resolution, so we will have to move in a range between 30mm and 50mm. - Brightness:
It should be between 3.5 and 6 to be considered normal or very good. - Field of view:
It is the width in meters of the area visible through the binoculars at a distance of 1000 meters. Always depending on the fact that the higher the magnification of the binoculars, the smaller the field of view. - Focusing:
It is usually done through a wheel or by means of a cam. The minimum focusing distance is very important because sometimes we also need to observe objects at a very short distance. It should therefore be at least 8 meters. - Eye Relief:
This refers to the distance that must be between the eyes and the binocular so that the pupil equals the exit vision. The greater the distance, the more comfortable it will be. - Mount:
It will mark the resistance of your binoculars to adverse weather conditions. Water resistant or waterproof (submersible) and highly resistant to shocks are desirable features in the mount.
It is very important before making the purchase decision, to know what we want to use our binoculars for, as it will depend on the characteristics that we will require for some occasions or others.
- Initiation or General Use: it is best to opt for bright 8x40 binoculars, with a wide field of view and comfortable size and weight.
- Ornithology: the 8x40 is still a very good option but if we want to see birds at long distances we will opt for higher magnifications over 10x.
- Night use: with a minimum of 50x magnification.
- Mountain: we want a light and compact binoculars in 8x30 or 7x30 models,
