your manual will talk about how to clean your image sensor, and i (and i expect a lot of other people will say the same) will tell you... if you don't think you can do it, DON'T DO IT. your sensor is the heart/soul of your camera and if you damage it, you're more or less screwed. the safe bet (although it'll cost you some) is to send it in. on the upside, you may be able to get them to recalibrate it while they're cleaning it.



true story... i had a friend who cleaned his sensor with an airbrush. he took the brush off but forgot about the little metal ring. the ring fell off right ONTO the sensor and it ruined not only the sensor, but the shutter. so he's screwed.



i don't have my manual on me, so i don't have a page number for you, but if you look in the index for image sensor or sensor, you should be able to find it. it's toward the back.



but having said all of this, once it's clean, the best way to prevent this from happening later on is to turn off the camera before you change lenses (so you don't accidentally open the shutter), inspect the rear of the lens before you put it on (and remove any dust you might find), and probably most important, try to avoid changing lenses out in the open air. there are arguments that say point the camera down when you do change lenses and some that say it doesn't really matter. i point mine down because to me, it's harder for dust to fly UP into the camera than it is for it to float down.



so BE VERY VERY ***VERY*** CAREFUL if you do it yourself. i can't stress this enough.
