How to clean the image sensor (E-mount cameras)

    Remove dust and debris using a commercially available blower. Do not use commercially available cleaning solutions or cleaning papers. Doing so may damage, deform or scratch the image sensor.

    For details on cleaning, see the instructions below.

    What you need


    [1] Blower
    Use to remove dust and debris from the body and from inside the camera.

    [2] Brush
    Use to remove dust from the camera body and lens. We recommend that you use both large and small brushes for the lens.

    NOTE: We recommend a plain blower instead of a brush blower, etc.

    Plain blower (recommended)
    Squeeze the bulb with your fingers to force the air out. You can easily adjust the air pressure.


    Brush blower
    This can be used as both a blower and a brush. When using a brush blower with a removable brush, remove the brush when using it as a blower. This prevents dust on the brush being blown onto the camera.

    • Do not use a spray blower. Doing so may damage the image sensor, or cause a malfunction.
    • Do not touch the sensor's surface or blow on it too hard.
    • Sony is not liable for any incidental or consequential damage due to mishandling at non-Sony service locations or otherwise.

    How to clean

    1. Remove dust and debris from the camera body.
      Use a brush to sweep dust and debris from the entire camera. Use a large brush for the outside of the camera and a small brush for delicate parts. Do not press the brush hard against the camera; sweep gently.

    2. Remove dust and debris from delicate parts using a blower.

    3. Take the front lens cap off, and remove the dust on the lens surface using the blower.
      Replace the front lens cap to prevent dust from attaching to the lens.

    4. Press the lens release button, and detach the lens.

      *For the ILCE-QX1

      IMPORTANT: Be careful do not touch the sensor's surface.

    5. Use the blower while holding the camera facing slightly downward so that dust and debris easily fall off the sensor's surface.

      *For the ILCE-QX1
    6. Reattach the lens.

      *For the ILCE-QX1
      • When you attach the lens, confirm that the mirror has been completely pushed down.
      • Take the lens off and on in a dust-free location. Dust and debris may easily enter the camera and lens in a dusty location.
    7. After you are finished cleaning, check that dust has been removed.

      • Set the shooting mode to Aperture Priority (A), and the aperture value to F11.
      • Take a picture of a white wall, white paper, or the sky.
      • Make sure that no dust shows on the image.

    NOTE: Many camera shops also offer professional cleaning services for image sensors that may be able to be performed in a timely manner.

    If the issue is still unresolved, the product may require service.
