Precautions

Lens Care

About Condensation (Fogging of the Lens)

• Condensation occurs when there are differences in temperature and humidity as described below. Condensation can cause the lens to become dirty and lead to mold and malfunctioning, so exercise caution in the following situations:
  • When the camera is brought indoors from outside during cold weather
  • When the camera is brought into an air-conditioned car
  • When cold air from an air conditioner is directly blown onto the lens
  • In humid places
• Put the camera into a plastic bag to allow it to acclimatize to the surrounding temperature in order to prevent condensation. If condensation occurs, turn the power off and leave it for about two hours. Once the camera acclimatizes to the surrounding temperature the condensation will go away naturally.
