It is based on this thread: Is the A7C sensor a dust magnet (compared to APS-C)?
I have had several Sony APS-C cameras without IBIS and now I've moved to A7C full frame. While I almost never had issues with dust on sensor on those APS-C models when changing lenses, the new A7C is like a dust magnet. I started to search more information about the issue and found that I am not alone.
The difference may caused by the lack of ultrasonic sensor vibration cleaning. Olympus cameras use this feature and reportedly the Sony (mirrorless) ones without IBIS as well, it is activated when the camera is powered off. But not the ones with the IBIS. The A7C cleaning mode just "shakes" the sensor by the IBIS motors and isn't that effective. The only Sony IBIS camera that is supposed to have the ultrasonic sensor vibration cleaning is A7S3, but the A7C is a newer model and doesn't have it again.
That would have explained the difference in sensor dust "magnetism" among different models and brands, but it seems as the issue may be more complex and deserves an article.
Thanks.
