How to clean a dirty SLR lens?

Fingerprints and dust on the lens will reduce the performance of the camera. It is best to wear anti-ultraviolet glasses when buying, and there must be a certain method to wipe the lens, otherwise it is easy to scratch the lens.

Method 1:

When cleaning lenses, we choose the following tools: professional mirror cleaning cloth/suede (never glasses cloth), professional lens paper, soft brush, balloon blowing, mirror cleaning water, etc. (These can be bought in professional equipment stores.)

If there is dust, blow it off with a balloon first. If you can't blow it off, you can sweep it with a brush. Remember not to touch the soft brush with your hand, because there is oil in your hand. Then, the mirror cleaning liquid drops are wiped on the mirror cleaning cloth from the inside out. Pay attention to several times, and don't push too hard at a time. Then use a balloon to blow off the remaining dust.

Method 2:

For example, in the case of insufficient equipment, we only have mirror cloth or mirror paper.

Then the way to blow the lens is to hold your hand in front of the lens at an angle of 30~45 degrees, and blow into your hand with your mouth. The air will reflect on the lens and blow away the dust. This has the advantage of preventing saliva from blowing on the lens.

Method of cleaning lens: Breathe into the lens (equivalent to the role of mirror cleaning liquid) to prevent dust from scratching the lens, then wipe the lens with mirror cleaning cloth or mirror cleaning paper, and spin out the wiping method from the inside out.

The combination of the above two simple methods can clean the lens in an emergency, and the first method must be followed at ordinary times.

2. Some preventive measures

After use on the beach or near chemicals, thoroughly clean the lens and fuselage.

If the camera breaks down, don't disassemble it by yourself under any circumstances, but send it to the maintenance department for repair.

Do not use solvent benzene, pesticides and other volatile substances on the camera to avoid camera deformation or even dissolution.

Don't put the digital camera in a closed car in the sun. High temperature will not only deform the plastic shell, but also shorten the service life of digital cameras.

3. On the LCD screen

The most common thing is that there will be fingerprints of fingers or some oil and dust, which looks disgraceful. Generally, it can be wiped with a detailed glasses cloth. Remember to wipe gently and be careful not to use strong glass cleaner, because some digital cameras have an anti-glare film on the LCD surface. Once the film is damaged, it can't be repaired, which is not covered by the warranty. In addition, you can also buy and use a screen protector. Just take it back and cut it into a suitable size and stick it on the LCD screen to prevent the LCD screen from being scratched.

But now most digital cameras have improved the LCD, and the outer layer is a layer of glass, so you don't have to pay too much attention to adding screen protection stickers on the LCD, so it looks clearer. Don't let these stickers stop obstacles and make shooting interesting.
