Cameras and lenses don’t have to be left everywhere, they need to be stored properly and correctly.
If it is not stored correctly, it may cause problems such as dust contamination and mold formation.
In this article, we will introduce how to store cameras and lenses.


● Precautions for storing cameras and lenses

One thing to keep in mind when storing cameras and lenses is dust and moisture.

If dust gets into the lens or camera sensor, it cannot be easily removed and may have an unwanted effect when shooting.

In addition, moisture can cause the lens to fog up and mold to grow.

If dust gets inside the camera or lens, or mold occurs, the only way to prevent mold is to disassemble and clean it, so it is important to prevent mold from forming.

In addition, cleaning the camera and lens (removing dust and mold) is not covered by the manufacturer’s warranty. If you ask for repairs, it will cost you a reasonable amount.

(The warranty is applied immediately after purchase, but not in the case of repairs.) )

Therefore, care must be taken to store it from dust and moisture.


● What is the best storage method?

The inside of cupboards, drawers, and desks are places where dust and mold are likely to form. The same is true even if you have it in your camera bag. In general, the humidity suitable for storing cameras and lenses is about 40-50%. If the humidity exceeds 60%, mold is likely to grow, and conversely, an environment with extremely low humidity is also undesirable.

Therefore, it is important to maintain the right humidity.

You should also pay attention to temperature differences, as sudden changes in temperature can cause condensation.

① Prepare a case to store your camera and lenses


First, prepare a case (storage container) to store your camera and lenses.

By placing it in the case, it prevents dust from entering, and by sealing it, it prevents moisture from entering.

Some common types of cases include:

~ Dry box (moisture-proof cabinet) ~


This is a dedicated moisture-proof storage room for storing cameras and optical equipment.

There are various types from small to large cabinet types.

It can maintain a constant humidity at all times, so you can store it with peace of mind. It is sealed and protects against moisture and dust.

~Simple dry box or sealed container~


 Simple dry box is easy and popular.

It is a sealed moisture-proof case provided by camera accessory manufacturers, etc., and it is possible to control humidity by putting a desiccant inside and placing a simple hygrometer.

It is easy to use because even beginners can easily store cameras and lenses. Recently, it is also possible to substitute airtight containers for food with rubber seals on the lid, which are available at 100 yen shops and home centers.

It is cost-effective and protects against moisture and dust, but requires regular humidity checks and desiccant replacement.




② Prepare the desiccant


Simple dry boxes and airtight containers for food should be filled with desiccant to reduce humidity.

You can also substitute a commercially available desiccant for dry boxes or silica gel for food.

Be sure to include a desiccant and a hygrometer to check the humidity.





③ Clean thoroughly before storage


Cameras and lenses that have been used may have dust on them.

Properly clean it before storing.

It doesn’t make sense to bring dirt in when storing cameras and lenses in an enclosed space.

④ Cleaning and cleaning of cameras and lenses


Use a blower provided by a camera accessory manufacturer to blow away dust and fine particles from the camera and lens.

Carefully wipe off dirt and oil on the surface with a cleaning cloth.

Sweat and oil on your hands can lead to mold growth, so wipe them off thoroughly.

It is a question of whether or not to remove the lens from the camera when storing it, but it is okay to store it with the lens attached.

Rather, by reducing the number of times the lens is attached and detached, the risk of dust contamination can be reduced.

However, if you are going to remove the lens, it is important to attach the cap to the camera’s lens mount and store it.


● Temporary storage of cameras and lenses

Care must be taken when temporarily replacing the lens. Even if you can’t see it, there is dirt, dust, and dust floating in the air.

Even at home, you can see that dust accumulates on shelves.

When replacing lenses, the risk of dust and debris entering increases.

Therefore, you need to be very careful about how you place your camera and lenses.

When you buy a camera or lens, it may come with a cap (lid).

Installing the cap as soon as possible reduces the risk of dust contamination.

When changing the lens, it may be temporarily placed on the desk, but care must be taken when doing so.

Make sure that the surface of the sensor or lens is not facing up, and that it is placed sideways to prevent dust from adhering to it.



 Even if the camera sensor is placed sideways, there is still a danger. Therefore, it is advisable to install the cap as soon as possible. 


 Even if the surface of the lens is placed sideways, there is still a risk. Therefore, it is desirable to install the cap as soon as possible.


 Attach caps to both ends of the lens and attach caps to the camera body.
