Cleaning the image sensor

If dust or debris gets inside the camera and adheres to the surface of the image sensor (the part that converts the light to an electric signal), it may appear as dark spots on the image, depending on the shooting environment. If this happens, clean the image sensor quickly by following the steps below.

  1. Turn off the camera.
  2. Detach the lens.
  3. Use a commercially available blower to clean the image sensor surface and the surrounding area.
    • Hold the camera slightly face downward so that the dust falls out.

  4. Attach the lens.



  • Do not use a spray type blower as it may scatter water droplets inside the camera body.
  • Do not put the tip of a blower into the cavity beyond the lens mount area, so that the tip of the blower does not touch the image sensor.
  • When cleaning the image sensor with a blower, do not blow too hard. If you blow the sensor too hard, the inside of the product may be damaged.
  • If the dust remains even after you cleaned the product as described, consult the service facility.
