4. How to measure the quality of the lens?
The most intuitive way is to compare the resolution (that is, clarity) of the lenses. The better the lens, the higher the clarity, especially when comparing the resolving power of different quality scopes in long-distance or dim light conditions.
5. How to measure the quality of the scope?
In addition to the resolving power of the lens and the difference in color reproduction, the quality of the optical sight is also reflected in the surface processing technology; often the better the gun sight, the more attention is paid to the appearance technology, and sanding and other processes are often used, especially It is from the 3-9 red light lighting series. It is neither slippery nor sticky to the touch, and feels very good! In addition to the above, the most important thing is that the scope must be able to withstand the impact of the recoil of the weapon, and the change of the axis of the scope under the impact must be within the required range!
6. What is the appropriate magnification of the scope? Is there any fixed ratio between multiples and distance?
The larger the magnification, the smaller the field of view of the scope, which is not suitable for quickly capturing the target. If you use a large magnification at close range, it will be difficult to find the target at once. Generally speaking, when using a gun sight within a distance of 100 meters, 4 times is a common magnification, and if you use it, 3-6 times the range is enough. However, if it is used in medium and long distances, it can use a multiple of a large magnification, and it can even be 24 times depending on the situation. Theoretically, the higher the magnification, the stronger the accuracy, but the high magnification gun sights have complex technical requirements to achieve accuracy. The cost is also significantly increased! There is no special regulation that must say how far the x magnification must be applicable. It depends entirely on environmental factors (because the magnification The bigger it is, the less the illumination of the gun sight and the smaller the field of view. If the ambient light is not strong and the distance is far, but the gun sight with a particularly high magnification is still used, it will be difficult to observe!) It depends on personal habits !
