Must-read for professional killers

Industrial lens


Murder footage? Yes, you are not mistaken. I believe that many people will blush when they see the word "murder", "How can you still love if you can't love it?" But do you know that maybe an incorrect wipe may cause permanent wounds to the lens. Say I'm alarmist? Then listen to me carefully.


The camera lens is a very precise optical instrument, usually the lens of the lens is composed of glass. As we all know, glass is a relatively hard material, but at the same time we must know the reason of "water dripping through stone", no matter how hard glass can not stand repeated or vigorous cleaning.

▲ Try to find a professional to clean the lens if possible

When you see this, do n’t be lucky. The following four situations may cause irrecoverable damage to the lens. If you want to be a lens killer, you can learn the following four tricks. If you want to protect your lens, it is best to avoid the following four situations.


Wipe the lens often


Hitman type: Clean-type


Killer: wipe 7 days a week, 5 times a day.


Killer Psychology: My camera is not for taking pictures, but for distressing. The lens should be wiped if it is dirty, and a piece of dust cannot be accepted.

▲ Wipe frequently, take lens paper, glasses cloth, and suede with you


Note for photographers: Dirty lenses do affect the picture, but as long as the lens is dusty, is it unacceptable? actually not. A little dust on the lens does not affect the picture at all. So it's best not to have cleanliness, it is not necessary to wipe it with a little dirt or dust, otherwise it will be exhausting and ruin your lens. The lens surface has a more delicate coating. Although it won't be damaged by rubbing, it should develop good habits. If it is wiped frequently, the soft wipes will also damage the lens for a long time. Wipe the lens as much as possible and choose lens paper.

You can wipe it with a soft object


Killer Type: Heart Large


Killer: Get the camera and rub it hard.


Killer psychology: Whether it is fabric or lens paper, it is softer than glass anyway, so you can wipe it hard with a hard wipe.

▲ Don't try so hard, the lens is not a glass window


Note to photographers: Although the lens paper is relatively soft, rubbing the lens by folding and rubbing it can easily cause acute angles to hurt the lens. This problem is easily ignored by everyone. Don't rub it hard when you encounter stubborn stains. Even the softest lens paper can't bear the force of your fingers.

Feel free to use cleaning fluid


Killer Type: Trustworthy


Killer: Use cleaning fluid often and spray it directly onto the lens.


Killer psychology: Since the lens cleaning solution is specially designed to clean the lens, you can use it with confidence. Multi-purpose lens cleaning fluid is the safest.

▲ Poor lens dripping with cleaning fluid


Note to photographers: The cleaning solution is used to deal with some stubborn stains or mildew, so the frequency of use should be relatively low. If it is used repeatedly, especially some low-quality products, there is also the danger of removing the coating. And if it is not used properly, such as spraying or dripping the cleaning solution directly on the lens, it will seriously corrode the coating, and the more it gets wiped over time, the more it will spend.

Volatile alcohol can be used as cleaning liquid


Killer type: do not know how to pretend


Killer 锏: Anyone who can decontaminate can make a cleaning solution


Killer psychology: I am a master of chemistry, why should I use lens cleaning fluid like people who do not understand. Alcohol and other volatile or fat-soluble degreasing is the best.

工业镜头

▲ Alcohol is lens poison


Note to photographers: First of all, we must know that volatile liquids such as alcohol actually have a difference in purity. Take alcohol as an example, industrial alcohol generally has a relatively high content of methanol and other impurities, and even medical alcohol has a lot of purity impurities. After the alcohol evaporates, it will leave a white impurity residue, which makes cleaning more troublesome. Moreover, high concentrations of alcohol may directly corrode the coating.
