What should I do if the SLR lens gets dusty? Is there any way to remove it?

Here you are. Let's see if you can use

as one of the most precise components in the whole camera. There is a direct connection between the daily maintenance of the lens and the output of high-quality photos, especially the lens of SLR cameras. Let's introduce the tools and uses of lens cleaning to you first.

First of all, lens paper, which is one of the most traditional lens cleaning tools, has the advantages of very fine fiber, soft paper and low cost, so it really won the favor of most photographers in the early days. At present, there are 1 copies in a book, and the price is around 2 yuan. I don't use lens paper very much now. On the one hand, the price is cheaper, and the quality of paper is getting worse. On the other hand, the softness of paper can never be compared with that of cloth. However, when you encounter stubborn stains, you can use disposable lens paper, fold it into a triangle, and wipe the lens surface with a little distilled water in one corner.

followed by suede, which is one of the traditional lens cleaning tools and has been completely eliminated. The reason is that although the price is cheap, it is still not clean after rubbing and rubbing, and it is very depressing.

consumer digital cameras often use lens cloth to wipe the lens. At present, the most popular is the 3M magic cloth. It is made of imported superfine fiber raw materials, which has strong decontamination rate and does not damage the surface. Due to the special technology, the dust accumulation and dust hiding are 4-5 times higher than other lens fabrics! The price is not expensive, around 15 yuan.

Most users of lens pens are high-end users. Of course, there are also mini lens pens designed for small-caliber lenses, but the price of more than 5 yuan is prohibitive. The working principle of lens pen is to use the grinding effect of toner to clean. Because the hardness of toner is far lower than that of lens coating, it will not harm the lens, and it is the best lens cleaning tool at present. Its other end is a brush. Lenspen brand has the highest share of lens pens in the market, and its price is around 7 yuan. At the same price, MINIPRO and DIGIKLEAR are both first-class products.

The most important tool for cleaning the lens is air blowing, which is also the first process of cleaning the lens and the most frequently used tool. For judging the quality of an air blowing, we mainly consider the air storage capacity, material and air flow principle. The most traditional medical ear washing ball, that is, the leather tiger is the cheapest air blow at present. Its price is only 5 yuan, but it feels very bad, and the air inlet and air outlet are universal, which is easy to cause circular pollution. The price of mid-range air blowing is around 2-3 yuan, and the price of high-end Swiss AF air blowing is around 6 yuan. They all adopt independent air inlet and outlet designs, and the main difference is the feel and workmanship.

the last thing to mention is lens water. Perhaps everyone has a cleaning kit given by the dealer when buying a camera, including the so-called lens water. Here, the author reminds everyone that the composition of this lens water is unknown, and the price of the whole set is around 2 yuan. What fools people is probably tap water! There is no need to use lens water for the lenses of consumer digital cameras. For some SLR lenses, it is not recommended to use them unless absolutely necessary. Even if you want to buy it, it is recommended to buy imported lens water. The more famous is the German-made HAMA lens water, which is in a 15 ml small bottle at the price of 7 yuan. Kodak lens water, the main components are water and carboammonia, and the price of a small bottle is around 8 yuan; ZEISS's lens water is the most famous in China. For the convenience of use, ZEISS's wet lens cloth is also sold, and the price is also less than 1 yuan.

Daily lens maintenance doesn't mean cleaning the lens every day. The tiny dust and water stains on the lens surface have little effect on imaging. You should never expect to wipe the lens out of the factory. For the lens of consumer digital camera with small aperture ratio, it is enough to blow off the dust on the lens surface with air. If you encounter a large area of stains that cannot be blown off, you can gently wipe it with a lens cloth (blow first and then wipe it, the order cannot be wrong, and the steps cannot be less). If it is a SLR lens, it is better to wipe it with a lens pen, usually from the middle of the lens to the periphery, in a spiral circle. One thing to be reminded here is that the lens pen is specially designed for optical lenses. It cannot be used on wet surfaces, especially when dipped in water, otherwise it will fade.

if lens water is needed to clean the lens, cotton should be prepared in advance. First, make 3-5 smaller cotton balls and press them into cakes, the size of which is one-third of the mirror surface, and then prepare 3-5 large cotton balls and press them into cakes, the size of which is two-thirds of the mirror surface. Dip a small amount of lens water into a small cotton ball, and then wipe the lens surface spirally from the center. Then, wipe it with a large cotton ball in the same way while the lens water is still wet.
