Domestic UV mirror:
I think the most common filter is the UV lens. Not so much that it can improve the photo effect, it is better to say that it is the best protective lens for digital camera lenses. During the trip, wind and rain are inevitable, and the seemingly humble dust may become the deadly killer of the delicate lens! This is the role of the UV lens. It not only prevents rain or other water droplets from invading the lens, but more importantly, it can effectively prevent the coating on the lens from being scratched by sand. Therefore, a good UV mirror is essential for traveling.(Note: UV lenses were previously used to absorb ultraviolet light, but this function has been weakened in digital cameras. Therefore, most people now equip digital cameras with UV lenses for the sake of lens protection.)
UV lens can filter out ultraviolet rays, which is not harmful to black and white and color negative images; it can also be often left on the lens as a protective lens.
For digital cameras, UV is mainly used to prevent fingers from touching the lens and dust from entering the lens. As for the function of filtering ultraviolet rays, it is second.
In addition, before using filters such as CPL, remove the UV as much as possible to reduce the chance of imaging circles and improve the image quality.
When facing the light source, especially the night scene, please remove the UV. Otherwise the glare will be more severe. .
UV lens is suitable for shooting in the seaside, mountain, snow field and open area, etc. It can reduce the blue tint caused by ultraviolet rays. At the same time, for digital cameras, it can also eliminate the interference of ultraviolet rays on the CCD, which helps to improve the clarity and color reproduction.
Filter protection:
The most ordinary photographic lens is also more expensive than the best filter, so it is worth the investment to install a protective lens in front of your favorite lens. While playing a protective role without losing the optical quality of the lens, the lens must be made of high-transparency optical glass without any chromatic aberration. The extremely strong MRC coating technology can effectively enhance the protective effect and is easy to clean. Fingerprints and oil stains are also It is easy to erase.
Please note: the area of ??the image sensor of a digital camera is small, and the depth of field is much larger than that of traditional film, so a lens with a short focal length is more sensitive to the impact of impurities on the front of the lens.
Any filter lens can only guarantee high image quality when it is clean. The robust, waterproof and antifouling MRC coating technology can reduce the possibility of the filter being scratched by hard objects. If the surface of the lens is contaminated with dust, water droplets or other contaminants, regardless of whether it has been removed, please remember the following methods of use:
1. Do not wipe dust or other contaminants on a completely dry surface, because the dust itself may contain sand with higher hardness, which may scratch the glass surface.
2. The correct step is to blow off the dust on the surface of the lens, then clean it again with a clean soft brush, and finally wipe it gently with a microfiber lens cleaning cloth.
3. A breath to the lens is a simple method used all over the world. It has a certain cleaning effect on oil stains and slight chemicals. Of course, it is possible to use a special lens water effect better.
