Key points of lens maintenance of digital camera

The lens of the camera is the most in need of maintenance. How can I maintain a good lens? The following are the main points of digital camera lens maintenance that I have compiled. Welcome to read!

1, moistureproof is the most important

If the humidity is too high, the lens is easy to mold, while the climate in the south is hot, and the lens is easy to mold. It is no exaggeration to say that there are "ten heads and nine models"; The air in the north is dry and relatively better.

Many people think that it is enough to put the lens in a drying oven and use desiccant to remove water. Actually, this is not the best way. The best way is not to wrap the lens too tightly. The best way to prevent the lens from moldy is to put it in a ventilated environment, let the lens be fully ventilated and dry, and then put it in a drying oven for preservation.

2, pay attention to waterproof

Water entering the lens is as harmful as water vapor entering the lens, so it must be cleaned in time. After a long time, it will certainly become moldy and cause short circuit of electronic parts. Especially when it rains, pay more attention to waterproof. Nowadays, digital lenses are equipped with circuits, and the anti-shake function, ultrasonic focusing and automatic iris control can only be realized by circuits. You can't take risks, or the lens may be scrapped.

3. Prevent vibration

Preventing vibration is a key problem. There are many trajectories in the lens, and vibration can easily lead to screw loosening. As long as it protrudes a little, it will affect the rotation of the lens and it is impossible to focus with the lens. Although some lens screws have been fixed with glue, they will still loosen under long-term vibration. Many people go out to make movies, and the shots are all in camera bags. Because the car bumps for a long time, the screws protrude, the lens can't rotate, and the focus can't be carried out.

Step 4 clean the lens surface

Blow off the dust with a balloon first, and carefully remove what can't be blown off with lens paper. Be careful not to use force. Take a little absorbent cotton, dip it in lens water to make it wet, and carefully stick off the dust and stains still on the lens. First, prepare a number of smaller cotton balls (or wet lens paper) and press them into cakes, the size of which is one third of the mirror surface. Prepare several large cotton balls and press them into cakes. The size should be two-thirds to three-quarters of the mirror. Try not to expose cotton fibers on the working face. Dip a small cotton ball into the lens water and do it well. Wipe the mirror spirally from the center, and don't look back. Then, when the lens water is still wet, gently wipe the mirror with a big cotton ball in the same way. If the first time you are not satisfied, you can do it again, but don't use the used cotton ball again. What if there is no lens water? It doesn't matter, you can use the lens face breathing instead. But be careful: don't pout when breathing. You should open your mouth wide and breathe gently so that you won't throw up. All we have to do is create a mist on the lens surface.

It is worth reminding you: Never let the lens water contact the lens surface, use lens paper, otherwise it may damage the coating of the lens or the lens water seeps into the lens along the edge of the lens, resulting in fogging or even degumming of the lens.
