Your camera is not sealed because it is weather resistant.

Your camera is weather-resistant, not weather-sealed. Your camera is not waterproof, thus this implies. What a significant change. It is crucial to comprehend this since it may result in photographers not being able to distinguish between them. This is particularly true for beginning photographers who are unaware of the robustness of their camera equipment. Even years later, seeing a photographer take a camera and lens out of their pocket without any safety precautions traumatizes me. So let’s get started.

What exactly do these words mean?

The camera is totally weather-sealed against the elements. This is mostly incorrect.
The camera is resistant to the elements and the weather.
The camera is splashproof, dustproof, and capable of withstanding moisture.
You’ll note that we didn’t mention waterproof. Only when all the doors and seals are fully closed are very few cameras watertight.

It may get tricky from here. Manufacturers of cameras allude to their weather-sealed durability designs. They’ll make statements like “their cameras and lenses have weather seals,” etc. These are true, but it does not imply that they are entirely weatherproof; rather, they are just more weather-resistant to environmental risks.

Additionally, you should look for illustrations showing how weather resistance is accomplished. The following are the important areas to check on a lens:

Can dust or moisture enter from the front element? Do you need a UV filter?
Is there a rubber gasket on the mount? A manufacturer that claims the seal is enough to keep out the elements is not someone I would trust. Nikon is an exception, since it builds its lenses with a lip that covers the whole camera mount.
The buttons: Many lenses don’t have many buttons since having too many might make them less weather-resistant.
Similar to buttons are the switches.
Weather-resistant seals are required for the rings, including the control, focusing, and aperture rings.
Cameras nowadays vary greatly. On a camera’s schematics, check for the following weather-resistant seals:

Batteries door
The keyhole
The trendy shoe
The switches
The knobs
the scope of
The toggles
It’s LCDs
The ship’s doors
The tripod attachment
Area of the strap lugs
There are a few typical methods for doing this. Rubber gaskets and overlapping materials are used to accomplish it. A lens or camera that is resistant to the elements is produced when this is combined with the appropriate amount of pressure.

The situation gets more worse from here: even if the camera’s maker claims that it is weatherproof, your warranty probably won’t cover it. Why? I’m not sure. That, in my opinion, is stealing. And there is a significant issue with cameras and lenses in the whole picture business. Even though your camera doesn’t have a weather-resistant construction, some technicians and representatives will assure you that it will work just fine in the rain. This wording is careless. It incites a photographer to endanger their work with the threat of paying the price afterwards.

So why is any of this relevant? A weather-resistant design, however, is not limited to outside use. Additionally, it suggests that your product is stronger and will likely last longer. Your sensor won’t get as filthy as a result.
