I did not notice it until today when I took a picture of the sky. I have outlined them in the example picture below. I have had the camera less than week and a half and only changed lens in the last few days. I keep the camera in a camera bag and I'm very careful when changing lens. After noticing this I have tried all three lens and it is there. So I know it's not in the lens, it has to be in the camera. What does it look like to you. I can't see it when I look through the viewfinder. I have looked at the mirror, it looks clean. ????

Looks like large dust to me. It doesn't matter how careful you are; dust will always find a way in. Buy the cleaning supplies and keep them on hand. Don't be afraid to clean it yourself. Dust gets in so often that you need to be able to take care of it rather than send it out for cleaning. You'd never have your camera if that were the case.
Edit: grammar

I heard advice on turning off camera before changing lens will help some dust to stick to it. I know it's impossible to keep it dust free, but is this true?

| It most certainly does look like sensor dust. I experienced the same thin very shortly after I purchased my 300D 1.5 years ago. I was able to eliminate it with air pressure from a squeeze bulb and have only had to do it once since then. |

remember to turn off the cam before changing lenses. more static electricity when there is current running through the cmos.
or maybe they are just UFOs ^_^

Scott, the easiest way to clean periodically is to buy a huricane blower--a squeeze blower, put the camera in cleaning mode, turn it upside down, and blow using the Huricane blower. So far, that's worked for me and I haven't had to use PEP pads (though I bought them).
To test, take a picture of the sky using F22. High apertures is where you'll see the dust on the sensor. You can do a test shot at the end of each day to see if you need to clean that night. |

| Thanks everyone. I will by a kit tomorrow from wolf camera. I have there one year warranty that covers everything even if I drop the camera in water. They will fix or replace it. It also covers cleaning of the sensor at the store level if they can. I will buy a kit [any recommendations?] but have them to clean it tomorrow. If they can't clean it at the store level I will request a new camera since it has been less than there 14 day return policy. Lucky I have a local store. |

| The most expensive, but easiest way, besides blowing with the hurricane, is the sensor brush. Rather than point you to the company, here's an article link |

| There is an interesting article in this week's TIME magazine. The Olympus Evolt E-300 SLR cam solves this problem by covering the imaging sensor with a transparent ultrasonic panel that shakes off dust and particles at 35,000 vibrations per second! |

If they can clean it, have them do so. If they cannot, don't exchange the camera. Most new cameras have some dust, and you 'll quite possibly wind up with just as much on the next cam.
Sensor cleaning is a part of DSLR life, and getting used to it is not that big a deal. I clean about twice a year, using the copperhill method, and it takes me all of 5 minutes. In between, I do not worry excessively about where/how I change lenses, because I don't mind occasionally cleaning.
In the days of film there was actually just as big an issue (maybe bigger) with dust; there were more opportunities for dust to enter into the imaging process.
