X Series: Fogging on Lens Guard

X Series: Fogging on Lens Guard

Applicable Models: ONE X, X2, X3, X4, X4 Air, and X5

Scenario 1: Fogging on the outside of the Lens Guard (Applicable to X3 Standard/Premium Removable Lens Guard, and X5 / X4 Air / X4 Standard/Premium Lens Guard)

Description

A layer of fog or tiny water droplets forms on the outer surface of the Lens Guard.

Reason

When the camera is moved from a cold environment to a warm one, moisture in the air condenses on the outer surface of the Lens Guard. This is a normal physical phenomenon (similar to eyeglasses fogging up).

Solution

You can gently wipe the outer surface of the Lens Guard with a clean, dry soft cloth or tissue to remove the fog or water droplets. This will not affect the normal use of the camera.

Scenario 2: Fogging on the inside of the Lens Guard (Applicable to X3 Standard/Premium Removable Lens Guard, and X5 / X4 Air / X4 Standard/Premium Lens Guard)

Description

Fog or tiny water droplets appear on the inner surface of the Lens Guard and cannot be removed by wiping from the outside.

Reason

The Lens Guard has an unsealed design to allow internal moisture to escape, greatly reducing the risk of fogging when not exposed to water. However, moisture may enter and condense inside the Lens Guard in situations involving direct contact with water or snow:

• Water, rain, or snow exposure: When the camera is directly exposed to water, rain, or snow, or used in highly humid environments with significant temperature differences—such as shooting in the rain, skiing against snow walls, or falling and getting snow inside the Lens Guard—small amounts of moisture may enter the Lens Guard. As the lens generates heat during operation, the moisture inside evaporates and may condense into fog when touching the cooler inner surface of the Lens Guard.
• High humidity & low temperature: In environments with high air humidity and low temperatures, the temperature difference between the moisture inside the Lens Guard and the lens surface can cause fogging.
• High humidity & sudden temperature drop: When the camera is moved directly from a warm, highly humid environment to a cold environment (e.g., from a lab at 77°F (25°C) and 60% humidity to an environment at -4°F (-20°C)), the Lens Guard may fog up.

Solution

Please rest assured that fog inside the Lens Guard will not damage the camera body. To clear the fog, unscrew the Lens Guard, and gently wipe its inner surface and the connection area on the camera lens with a clean, dry, soft cloth or tissue. Reinstall it only after ensuring both areas are completely dry. If water or snow accumulates on the exterior of the Lens Guard, clean it promptly to prevent moisture from affecting your shots.
