Know Everything About Weather Sealed Cameras

No matter whatever you do wind, rain, dust and dirt particles can cause serious damage to your photography equipment. Interestingly many DSLR cameras has an in build protection from such conditions and this is called as weather sealing.

Weather Sealing is protection of the internal parts of a camera from external influences such as moisture, dust, and humidity. It is formed from Gaskets and lining comprised of rubber and silicon provide most of the weather sealing to complement the design of the camera. Weather sealing on cameras is primary protection in build on cameras to protect these items from rain, dust and dirt etc upto a certain extent if not completely.

“Gaskets :- A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

But don’t be a fool man weather sealing is simply cannot be misunderstood with waterproof. Weather sealing is simply protection from these particles up to certain extent. However you have to take care of the equipment by yourself.

Weather sealing are simply not limited to the camera body but they are very much important on the camera lenses and other accessories also especially on the junction of the camera lens and body so that in rainy condition rain drops does not gets entered in the camera body which can harm the electronic equipment.

You must keep this in mind that weather sealed does not mean waterproof. Even a expensive waterproof mobile does not has waterproof guaranty in it as companies don’t offer it. So nothing can be completely water proof even those high end devices are water proof at certain depth and for particular time frame.

Even if the camera model is weather sealed if is advised always to cover the camera with a rain sleeve or cover for added protection especially if you are filming in rainy conditions or near a water fall or some water source. A added protection will always help you. It is advised to clean the lens by taking it out after few shots if you feel the lens is not focusing well enough.

Extra Info For Geeks :-

The protection is provided by both rubber sealing with silicon rings and gaskets as well as design considerations such as interlocking panels and pool resistant exterior pieces. Most obviously buttons such as the shutter release will be designed with either a rubber housing beneath them, or a gasket to prevent the entry of the elements. Sealing is not provided by a single piece of hardware. I have often seen values such as 60-70 silicon rings being used in a typical DSLR body for weather sealing, and 30-40 being used in a battery grip for example.

Weather sealing in all but the most high end professional serious cameras is a relatively new occurrence in the consumer market. One can now commonly find weather sealing even in cameras costing under $1,000 USD if you look for the right models.

Commonly weather sealing considerations are limited to moisture from weather such as rain, snow, humidity, and also dust and sand. I would argue that weather sealing does not end at that, but also includes anything that protects the camera from usage and keeps it working as designed. With this in mind I would also consider features such as magnesium-alloy chassis design, shock protection, shielding against electromagnetic interference, stronger shutter mechanisms, sensor dust resistance, carbon-fiber lip on lens ends, and even special fluorine coatings on the low-pass filters as all being components of weather sealing.

Where is it present :-

1) A camera is weather sealed if it has – you guessed it, weather seals. Most importantly on buttons and openings but also along the case. The level of weathersealing varies – and it is also weathersealed not waterproof which some people think it is.

2) A non-sealed lens can allow water to enter the camera via the lens but more importantly via the lens mount. I.e. a non-sealed lens breaks a camera’s weather sealing.

As to it being effective, well, you need to be the judge of that. People have used unsealed cameras in rain before without issues – others experienced a sealed camera failing in bad weather… Weather sealing means your camera is more likely to withstand humidity – it is not a guarantee that it will.

Which Olympus lenses are weather sealed?

  1. Olympus M.Zuiko Digital ED 8mm f/1.8 Fisheye PRO.
  2. Panasonic Leica DG Summilux 12mm f/1.4 ASPH.
  3. Olympus M.Zuiko Digital ED 25mm f/1.2 PRO.
  4. Olympus M.Zuiko Digital ED Macro 60mm f/2.8.
  5. Olympus M.Zuiko Digital ED 300mm f4.0 PRO.

Is Sony A7 weather sealed?

Yes it is water resistant. But it is till in dark because Sony did not explained it so it is little bit controversial.

I hope this article helped you, don’t forget to share.
