Cameras with automatic sensor cleaning

Sensor cleaning

— the presence in the chamber of the system of automatic cleaning of the matrix.

This function is relevant only for models with interchangeable lenses (see "Direction"). In the process of changing lenses, various contaminants, in particular dust, get inside the body; such contamination can lead to the appearance of artifacts in the images. To avoid this, cleaning systems are provided. They usually work on the principle of ultrasound: high-frequency vibration "resets" debris from the surface of the sensor.

Note that no cleaning system is perfect — in particular, such systems are “too tough” for condensate, salt deposits and other similar contaminants. So the matrix may still need manual cleaning (ideally, in a service centre). Nevertheless, this function allows you to effectively deal with at least dust, which greatly simplifies the life of the user.
