How to clean the lens and image sensor

    This article provides guidance on cleaning the camera lens and body by yourself.

    Before you start

    Prepare the following items to properly clean the camera lens and image sensor:


    • Blower: Use it to clean any dust and dirt on and in the camera.
      • Plain blower (preferred)

      • Brush blower

    • Brush: Used it to wipe the dust away from the camera body or lens. Use a small or large brush depending on the situation.
    • Cleaning cloth: Use it to wipe the camera or lens. We recommend using a synthetic fiber cleaning cloth that you can wash and reuse.


    • Don't use an air duster or compressed air as it may damage the image sensor or cause a malfunction.
    • Don't touch the surface of the image sensor or blow on it too hard.
    • Your product warranty doesn't cover any incidental or consequential damage due to mishandling at unauthorized service locations.

    How to clean your camera

    IMPORTANT: Make sure to remove the lens in a dust-free location to avoid additional dust from entering the camera.

    1. Use the brush to sweep away any loose dust or dirt from the camera surface. Use a large brush for the camera exterior and a small brush to reach corners and delicate parts. Sweep gently and don't press the brush hard against the camera.


    2. Use a blower to remove dust and debris from delicate parts.


    3. Remove the lens cap and remove any dust from the lens surface.


    4. If the lens surface is particularly dirty, you may use a soft cloth dampened with a lens cleaner solution. Lightly wipe with a circular motion from the center of the lens.


      IMPORTANT: Don't apply the lens cleaner solution to the lens directly or use organic solvents such as thinner or benzine to clean the lens.

    5. Attached the front lens cap to prevent dust from adhering to the lens.
    6. Press the lens release button to detach the lens from the camera. For detailed instructions, refer to the product manual.

      IMPORTANT: Be careful not to touch the image sensor.

    7. Tilt the camera slightly downward so that the dust falls away from the sensor.

    8. Re-attach the lens.

      Note: For an A-mount camera, make sure the mirror is completely locked down before you reattach the lens.

    9. Check that the sensor is dust-free.
      1. Set the shooting mode to Aperture Priority (A) and set the aperture value to F11.
      2. Take a picture of a white wall, a white sheet of paper, or the sky.
      3. Make sure the no dust spots show up on the image.
