How to Clean Sony a7iii Sensor & Rest of Others A Series Sony Camera

Recently one of my dearest friends was frustrated to share with me that, over the last six months, he needed a five-times cleaning of his Sony a7iii cam sensor without any proper reason!

Not only my friend, but many Sony users also may annoy to think that how could an image sensor get dirty so quickly! Wherefrom the dust and fiber can come, which later on accumulate on this sensor!

However, an opening or disclosing of the camera lens creates the chance of getting a contact of the external dust and fiber to the camera sensor.
