What Are Water Resistant Digital Cameras?

The evolution and history of waterproof digital cameras The so-called waterproof digital cameras should first appear as Casio's "G.BROS. GV-10", which debuted in November 2001. It uses a sturdy design. At the time, it was recorded that the JIS protection level was 6, and it also prepared a level 7 waterproof with more impact resistance, and a level 6 dustproof performance. Its successor, the GV-20, also debuted in 2002. The GV-10 is a body design that can recognize the outdoors, but when the Olympus "-10 DIGITAL" was released in early 2003, the "world's first waterproof metal body" was widely advertised. It achieves the effect that it will not be uncoordinated when it is usually used. The Sony "Cyber-shotDSC-U60" debuted in June of the same year. This is a waterproof and dustproof camera that supports underwater photography up to 1.5m.

There are two types of waterproof cameras. One is waterproof. This camera is not afraid of rain. Some cameras can shoot in water depth of 1 meter, but the time limit is only 30 minutes. The other is to add a waterproof device. As long as it is equipped with a diving box specially designed for digital cameras, ordinary cameras can shoot in water depths of 30 to 40 meters.

The principle of the diving box is to use a transparent cover slightly larger than the volume of the camera, with a complete waterproof treatment of keys and gaps, and the thickness of the cover is sufficient to cope with the water pressure indicating the maximum depth of use. .

First, ordinary type. Suitable for ordinary tourists, lovers of underwater activities. The price of the waterproof cover ranges from 1700-1900 yuan.

Second, sub-professional level. Suitable for photography

Waterproof cameras also need to be carefully maintained in use, don't mistakenly think that it has a diamond body.

1. The safest for waterproof cameras is fresh water below 30 . Water with too high temperature (such as hot springs or waters exposed to direct sunlight for a long time) can easily cause the rubber seals to age and lose their waterproofing ability. The salt content makes it very easy to rust metal parts, make buttons difficult to operate, and even corrode circuits. Therefore, it is best to immerse the camera in fresh water for several hours after shooting in the sea or sea water.

2. Although most waterproof cameras have a dust-proof function, sand or dirt with large particles can be a fatal killer to the camera. Be sure to rinse it with water (wipe with a cloth before replacing the battery or memory card, etc.) It is easy to scratch the surface of the machine and it is difficult to clean it completely). Otherwise, once the sand and soil adhere to the sealed area, it will easily cause deformation of the rubber pad and water leakage.

3. The sealing cover at the battery and interface can be said to be the weakest part of the waterproof camera. Before each camera enters the water, you must carefully check the seal of the sealing cover to confirm that it is securely closed. When opening it, you must be extra careful. After soaking, first wipe off the water on the body with a soft cloth to avoid infiltration. After opening the cover, there is likely to be a small amount of water on the upper edge of the internal rubber gasket. Pay more attention to dry it in time.

4. If your waterproof camera does not have anti-vibration function, avoid bumping, because it is likely to cause the sealing interface to loosen at the moment of impact.
