To throw another little element into the mix, when the shutter actuates, the hinges of the titanium blades rub and gaunch as the blades pivot aside and the mirror hinges pivot, all of this micro mechanical activity creates metallic micro dust right in front of the sensor and the mirror flapping up and down wafts it all around!
The general consensus has always been to store the camera bodies lens face down so that any dust settling does so either on the back of the shutter, the back of the mirror or on the lens cap, if fitted otherwise on the back of the lens.
Applying a sticky substance to the inside of the body cap may help but it's only a small area inside the mirror chamber and is only open to the front side of the mirror most of the time.
Always try to change lenses with the front of the lens downwards, that way any swarf, dust and particles should obey the rules of gravity and fall out of the front of the body during the process.
(ORIGIN mid 16th cent.: either from Old English geswearf 'filings' or from Old Norse svarf 'file dust'.)
Totally agree. I has always carried and stored my cameras in holster style bags....lens downwards. And I rarely need to clean my sensors.
