How to clean the SLR lens?

Lens is one of the important photographic equipment cherished by every photographer.

The most important and fragile part of the lens is the multi-group lens, in which the front group lens is the one we need to protect most, that is, the lens directly exposed to the environment in front of the lens that we can directly see.

Shooting in a humid and harsh environment.

In order to greatly improve the imaging quality of lenses used in modern lenses, coating technology is widely used. The high-tech coating on these lenses is nanometer thick, which can be said to be relatively expensive. If they are destroyed, the image quality will be degraded. Therefore, we should take the cleaning and maintenance of the lens seriously.

Before learning how to do routine maintenance of photographic lenses, it must be clear that every physical cleaning is the normal wear and tear of lenses, which will not affect the normal life of lenses, but the wrong cleaning method is the serious damage to lenses!

Therefore, we must master the correct cleaning methods and use the correct cleaning tools.

In daily maintenance, the first thing we should do is to try to avoid the lens from getting dirty.

It is necessary to equip the lens with protective glasses, which are much cheaper than the lens and relatively simple to use and maintain. But also play a good sealing and protection role for that front group of lense.

Try to choose protective glasses with good optical quality when buying, such as those with high-quality optical glass in big brands or high-transparency coating technology. Protective glasses can be used when shooting in harsh environment.

When using filter combinations, such as various gradient lenses or polarizers, we need to take off the protective lenses and put them back on after shooting. This can greatly reduce the probability of wiping the front group of the lens.

When using other filters, you can temporarily remove the protective glasses.

For the front group of the lens, you don't need to wipe it if it is a little dirty. If it is only a small dust or oil stain, and it is not dense, it does not need to be removed immediately. A little dirty spots will not affect the imaging, unless you want to shoot a backlight scene, the dirty spots will reflect light.

When it is really dirty and needs to be wiped, in fact, only three basic cleaning tools are needed:

The first is professional blowing.

The second one is a professional lens pen, with a toner head at one end and a soft brush at the other. It is a sharp tool to deal with oily dirt such as oil film and oil spot.

The third is professional lens cloth, which will not lose dander and can effectively avoid secondary pollution. When buying, buy big brands or professional brands, which are individually packaged.

If it is dust-free cleaning of vacuum-packed lens cloth, a new piece can avoid secondary pollution to the greatest extent, and it can also be used in different areas when it is used, and it can be discarded when it is completely dirty. If cleaning is necessary, it is recommended not to use it to clean the lens, but to clean the body or screen. When using lens cloth, it is best to use it with professional cleaner, and the effect is the best.

After the things are ready, you can start cleaning. Note that the above three tools pay attention to the order and method of use. If you are not careful, you may damage the lens! Remember!

The first step is to blow with air to blow off all the floating dust that can be blown off. Note: Before use, don't face the camera and blow it in the air several times to blow out the dust that may exist in the air to avoid secondary pollution.

Step 2, use the soft brush on the lens pen to wipe off the big particles of dust that can't be blown off. Pay attention to it once, then dry it with your hands and touch it again. Continuous contact with dust is absolutely forbidden!

Until all the dust that can't be blown out is blown clean, and then blown clean with air.

Step 3: Press the toner head of the lens pen flat on the dirty place, wipe off the oil film of the oil spot by drawing a circle, and blow off the remaining floating powder with air after all the oil stains are removed.

Step 4, wipe with lens cloth, preferably not dry, and use special cleaning solution.

Take a small amount of special cleaning liquid.

The method is to touch a small area of lens cloth with your finger (pay attention to avoid the place where you wiped it last time), dip a small amount of special cleaning liquid, and wipe it in one direction to clean the lens.

Hold it with one finger and wipe it in one direction.

At this point, a lens is easy and simple to clean.

Cleaning and maintenance is as simple as that.
