I'm a bit anal when it comes to having clean sensor and glass. But I'm also aware that overdoing anything is never a good thing.
My question is: if I have not changed the lens, that should mean that no new dust from outside the camera should come into the camera and therefore the sensor should not need dust blowing (provided it was dusted before the lens change).
Am I right or should I still try to blow the sensor after every shoot (regardless of any lens change during the shoot).
Sorry if the description is confusing
