Nobody seems to notice this mark but i see it on every picture.

Kind of your own watermark...
Seriously though, if this were in the same place on every shot, I would be upset. Does it show up only when using the Raynox adapters?

is this in the exact same position no matter what zoom setting is used .
Or does it cange size and position with the zoom change.
If it is always the same no matter what it is a sensor problem for sure.
Otherwise we shall need to see more pictures at other zoom settings.

If it is a sensor problem you will have to send it back to canon, complete with pictures.
It is probably the best option anyway.

the mark is in the same place each time i use the cameras own wide angle.it is not there when i zoom, so this makes me think it could be a hair in between the lens.not noticable at all when i use the raynox lenses.

I didn't notice it until I read your description. But now I know about it, I can't help being drawn to it.

Are there any marks on the lens at all? It could be some (very fine, very straight) dust on the inside...

not that i can see.it is not visable at all when i have a dull background but to me it sticks out like a sore thumb if i have a light background.

I have no problem at all in seeing it, but had you not given good directions, I could have just as easily never noticed it.

Once you have determined that it is a problem in the sensor, you should immediately send it away for repair.

Here is the best way to test the camera. Go into a very dark room and take a picture with manual settings, wide open aperture and about 2 seconds, while holding the lens cap over the end of the lens (or use anything that you can find that makes a good light-tight seal with the end of the lens - such as burying it under a pillow).

When you look at that image in an imaging program and when you post it here, we can all verify the problem.

Just to be on the safe side, take a similar picture of an all white wall, brightly lit, and and this time use Av mode, wide open lens and +1 1/3 Exposure Compensation.

cheers Bob, i'll try this as soon as i get a chance.i've just moved house so things are pretty hectic at the moment,but i will post the results asap.thanks again Simon.
