How to Pick Leica Binoculars
Binoculars are very useful for seeing at far distances. People use them for different purposes and hobbies, such as birdwatching, fishing, military use, and hunting. eBay has both Leica binoculars and monoculars.What do the numbers on binoculars mean?
The different numbers on the binoculars will usually be sets of numbers, like 8x40. The first number indicates the magnification strength or how many times closer the subject you are looking at will be closer to you. The second number is the size of the lens measured in millimeters. The size of the lens will show how much light the binoculars let in. The larger the lens, the more light will be allowed in through it, which will make the image brighter and more pronounced. Binoculars that have small lenses are usually preferred because of their compact size and portability.How do you choose the right Leica binoculars?
With binoculars, the higher the magnification, the steadier that your arms have to be. If you are considering a magnification above 12, you will need to also use a tripod or a stand to hold the binoculars. For good magnification with manual handling, a 7x to 12x magnification is fine. The lens size, which is measured in millimeters, has to be considered in terms of what lighting conditions you're going to use the binoculars in. The larger number will be more appropriate for low lighting conditions.What is the exit pupil of binoculars?
Exit pupil is the size of the light circle that appears when the binoculars are held at a short distance from the eyes. This value shows how well the binoculars perform in low light conditions. If the binoculars are held away from the eyes against the light, the bright circle will be seen in the center of the lens. Binoculars for a specific person should have the exit pupil the same size as their pupils. Because our pupils dilate during low light conditions, the binoculars should also be chosen with a greater exit pupil if they are going to be used with dim light.What is the lens coating of the binoculars?
The lens usually has a coating on it. This ensures that there is no glare coming from the light hitting the lens as it reflects on the water. There are four levels of coatings for the lens. The thicker the coating, the better protection the lens will have from the light. More coats will be appropriate for the lenses that are used in high lighting conditions such as people who use them outdoors. The different coating levels are:
- Coated - There is a single layer on one of the lenses.
- Fully coated - All the air-to-glass surfaces have a single layer of coating.
- Multi-coated - There are multiple layers on one or more of the lenses.
- Fully multi-coated - All air-to-glass lenses have multiple layers of coating.
