If you can see it in your viewfinder the only places it can be are the lens/focussing screen forgot about that! or mirror, if it appears on the photos then that rules out the mirror (as it moves out of the way for taking the pic.), you do not see through the sensor in the viewfinder.
It would be a massive coincidence to have dust on the sensor in exactly the same place as the mirror/focussing screen/lens!!

That is very strange. I can obviously see it through the view finder. Changing lens and it is still there. All of my photos show this dark, but faint blob or spot and its position never changes.
Does this indicate a fault with the camera as it cannot be the lens?
I cannot think of a camera fault which could cause this??
Unlikely as it sounds, the suggestion that it's dust on both the sensor and the mirror/focussing screen is the only theory that seems to work...unless anybody has some other suggestions?
I know Joe. This is one mighty strange thing.
I have posted the image here.
Can anyone shed any light on this please/
Welcome to the club! Looks like you got dust!
If that is dust then how come I can see it through the view finder?
Certainly looks like dust - to be sure take two shots of (as it's dark now) a blank wall, one at f5.6 and one at f16. If the f16 mark is clearer and sharper, and the f5.6 one very smudged or even not visible, then it's sensor dust.
Why you can see it in the viewfinder I know not.
Cheers Chris I will try that tip and let you know of the result.
"If that is dust then how come I can see it through the view finder?"
Alright then, it's not dust! You did ask!
From the photo you posted it's not just the one spot either, there are several other less dark ones visible. Can you see all of them through the viewfinder? If so then it really does become weird. If not then I'd say it's dust on the sensor and you just happen to have a spec of dust on the focussing screen too.
I tried your tip and it does appear to be dust on the sensor.
At f5.6 the blurb looks soft.
At f8.0 the blurb looks sharper and smaller.
At f11 the blurb looks even sharper and even smaller.
Does this ring any bells?
Yep, Mike, that's sensor dust.
It shows up sharper at smaller apertures because it's actually on the surface of the anti-aliasing filter, a couple of millimetres above the sensor surface itself. hence, the more diffuse light of larger apertures can "wrap" around under the dust particle and diffuse the shadow. Smaller apertures have less diffuse light so the shadow is sharper and clearer.
I guess that is something I have to start getting used to
I can just clone out the blurbs in Photoshop when they appear. After all they can be removed carefully according to the manual.
But Mike how come you can see it in the viewfinder, the optical path is different unless you have a foreign object between the lens and the mirror. If you take the lens off can you see anything. If its big enough to be seen in the viewfinder you should be able to see it straight off.
While you have it open look at the screen can you see dust on it. your camera is new so if in doubt send it back.
How clean are the backs of your lenses. It is one area you need to take care. Did you not have a similar problem with the film camera you bout from warehouse express?
