Is this dust already on my 1 month old 40d surly not, never had the lens off the camera sinse i put it on 4 weeks ago and only taken a hand full of shots.
this was one reason i bought this make, i could have gone for the olympus but i know canon was better for other reasons, but this was the buy or not to buy reason for me.. any ideas

still trying to post the photo sorry

Yes its most likely dust on your sensor.

A simple clean will remove it all, it is likely that if you don't change lenses at all it was there when you bought the camera in the first place.

bain i'm sorry to say that but it's normal with canon. i bought Canon 40D three weeks ago and it looked exactly the same. i took it stright away back to shop and asked them to clean it. after cleaning i still have 3-4 visible dust fragments but they are easy to errase in photoshop. and remember that you'll see them only when using F11-32. if you are going to do macro photography you'll see it on every single photo. but if you do portraits, landscape, architecture, wildlife and so on you won't see them.

I have had my 40d for a few months now and frequently change the lens. I know that I should not be saying this but I have been lucky so far.

You may want to look at the "dust data" function that the 40d has in one of the menu settings. I have never used it but I assume that it there to help in cases like this.

Had my 40D for about 4 months, loads of lens changes and no dust.

Don't know of any of my mates Canons coming like that, but hey who knows.

Maybe a time to learn how to clean the sensor, and get over the fear.

Luckily I still have none in my 40D, no stuck or hot pixels either

It's difficult to tell at this magnification, but I don't think that most of the debris is dust - it looks like oil splatter with a 'doughnut' shape.

I had the same problem when I first got my 30D, and I put it down to over-zealous lubrication of the shutter mechanism at the factory.

It's easy to remove, but you'll have to use a wet cleaning method such as Copperhill. After a while the problem will go away, but it is a bit annoying!

thanks.
you know it really narks me when i turn on the camera I see shining stars, oh lovley shiny stars on my lcd Screen say "Cleaning sensor" WHOS THE MUG HERE , Item not sold as discibed i think, and why should i spend all day in photoshop getting rid of black specs on my photos, instead i should be enjoying the photos. i can understand if i had it year of what ever and continuosly changed lenses but i dont Camera going back asap.
this rant was for me guys, getting it of me chest

thanks for the replies

Dust is a fact of life unfortunately, you just have to get used to cleaning the sensor occasionally. Just like dusting the house
It's not surprising there is some there from new, as I don't think that you can assemble things in a totally dust free environment. To be honest the sensor cleaner does a damn good job, my 40D has been in some dreadfully dusty nasty places when taking cycling shots & I don'd need to clean it as often as the 20D, only twice so far.

The Canon auto sensor cleaning system (allegedly) doesn't work too well anyway, but no built-in cleaning system will remove oil spray (if that's what it is). As Whipspeed says, sensor dust is something you have to deal with from time to time on all DSLRs, and cleaning the sensor only takes a few minutes. If you return the camera and get a replacement, or even another model, you'll still have to clean the sensor after a while.

3 Canon D-SLRs here and not had to clean any of the sensors ever. The 10D must be a good 5 years old and still no issue there.

I accept that all D-SLRs will get dust on the sensor over time but I think it's a bit unfair to single out Canon for criticism.

[bain]

i dont think i was singling out the canon thats the camera i have!.
now i know i would have to clean the sensor at some time i did my research before i bought a camera but to have it only 4 weeks and already having to clean the sensor is beyond belief, it's basicly been in the box, ok took some shots but not a lot.

put it this way if i had bought a car with a unique petrol filtering system and after 50 miles the car started to splutter and cough becuase the filter wasn't working i would not except it as , "well you know this happens "excuse ,i have a canon cleaning system on the camera and EXPECT it to work, after all i am the consumer and sick of being put in the box of, the brits never complain "it's not british", and stiff upper lip ] and all that.
i saved and saved to buy this Camera, and i expect all the functions to work properly
thanks

i have to say it works wonders on my 400D and i notice a huge difference on the 30D which doesnt have the cleaning sensor.
