One of the blowing
lens on the dust, it is best to blow the net, rather than wiping. Because many lens surface coating is very delicate, small dust particles will be scattered on the surface of the lens, if we directly wipe the lens paper on it, dust between the paper and the lens membrane surface acts as a sandpaper on the role of sand particles, it is very easy to damage the delicate membrane surface, and for the low-end consumer plastic lenses, the situation is even worse. So the right thing to do is to use a special air blowers, medical equipment stores are also available, the scientific name of the ear washing ball; or to the camera equipment city to buy, look a lot, but the camera equipment city has some plastic blowers, blowing is not very strong, rubber material is good, hold in the palm of your hand to the lens pinch and blow can be.
Two, wipe
Blowing clean dust and then do wipe. Generally for watermarks, stains, as much as possible to clean up in a timely manner, like saliva or acid-containing, alkaline rain stains on the membrane has a certain slight erosion, may damage the membrane surface over time. The way to clean up is to the lens ha a breath, with lens paper in the lens surface to clockwise or counterclockwise a direction to wipe, be sure not to wipe back and forth, wipe the point is: light into, slightly heavy wipe, and then light up for a process, and wipe over a process, be sure to change the part of the paper and then wipe. Suede is a very good lens wiping products, but artificial suede quality varies, do not use the good. Natural chamois leather if there are parts of the hardening, must not be used again, easy to scratch the lens. The current consumer DC lens are very small, with lens paper or chamois are not necessarily able to wipe clean, wipe the whole, recommended the use of special lens pen, one end of the brush, used to whisk away a little bit of dust; the other end of the self-moisturizing chamois head, the area is very small, but the use of the effect is good, it can be used to wipe away the stains on the small lens, and the big lens stains do not need to do a large area of the wipe, the only drawback is the price of the price is expensive, cheap The only drawback is that the price is expensive, the cheap one is about 50 yuan, and the good quality one is about 200 yuan.
Three, wash
If the lens stain surface is large, or traces of time left long, or sticky, simple wipe can not solve the problem, then we have to do a simple cleaning of the lens. Cleaning method is very simple, find a medical cotton swabs, that is, degreasing cotton balls, in the end of the stick must have a thicker cotton ball, in case the cotton ball is too thin, the stick scratches the surface of the lens. With a cotton ball dipped in a little pure water, and squeeze the water, that is, the wet state, in the stains in one direction for many times scrubbing, stain removal with an air blower to blow dry, and then use the lens paper to clean in the same way as 2. Do not use alcohol or other cleaning fluids if it can be wiped clean with water alone.
Four, protection
The above three methods are passive protection of the lens, and the most effective protection of the lens is to add a UV mirror for the DC, because a UV mirror is only a few dozen dollars, in the UV mirror and the surface of the lens surface of the table to form a relatively airtight environment, you can effectively isolate the dust. And the UV mirror cleaning can also use the above method, even if the damage is not necessary.
Five, dry
Whether it is the DC lens, or the body of the electronic components, to exclude the humid environment. So after shooting in the rain, or after wet cleaning of the lens, are recommended to wipe dry and placed in a drying box. In fact, the drying box we homemade, to the supermarket to buy a good seal, the size of the plastic storage box, collect a little desiccant (many electronic devices in the package, or part of the small food packages have) in the box can be.
