Question about "sensor" dust Anonymous
Not troll, but just an obvious question to you maybe.

When you take out the lens, what you see (with the focus points markings) is the mirror, right? And then that flips out of the way when you press the shutter and then the sensor itself is revealed, right?

So my question is, if dust somehow manages to get in through the lens let's say, wouldn't it just settle on the mirror? Then why is it possible to see dust specks when you shoot small aperture photos? Shouldn't the mirror move up and that's where most of the dust is anyway? Like it shouldn't really get on the actual sensor.

The shutter flapping around kicks the dust around and onto the sensor.

dust is small and sneaky. trust no one

whenever the shutter is opening there's a chance of some of that dust to get in, and the shutter itself can produce "dust" from friction I believe.

You have to remember that the mirror is a moving part. Dust is free to go whereever it wants. When the mirror moves, it would create a gentle breeze that would move any dust located inside towards the sensor. Having dust on the mirror doesn't really matter because it doesn't show up on the photo.

Oh I see, so it settles on the mirror and the movement might make it float down on the sensor?

So when people clean their cameras, do they do it on the mirror or the actual sensor? Can you actually clean the sensor? Isn't it like super fragile?

Fragile yes. Having clear pictures is better than having dust on every single picture.

By using the "mirror lock up" function on the camera, you point the sensor down and blow air into it with a high-volume air bulb. After loosening up the dust particles, gravity should take them out of the camera body.

Electrostatic trumps gravity.

What if I use a stronger electromagnetic field?

They do those tools but be prepared to get buttraped on them. Plus they don't remove burned on dust particles. A wet wipe is the best method usually (So I read). I have about 5 or 6 dust particles on my sensor at the moment because my 450D is new so I won't need cleaning for a while yet unless I shoot everything at F36 :P

Lol, those are expensive, get an aspirator or something and save the ignorance tax.

Some people uses the electrostatic from the screen of a CRT TV to attract the dust particles of the sensor by locking up the mirror, placing the camera in front of the televisor and switch the tv on.
Not bad idea, but I don't know how that electrostatic shock can affect the sensor and internals of the camera.
Anyone wants to try it?
