Hi there

I have just received my refurbed Canon 300D and I think it needs to go back :(

I have taken a couple of photos just to test and there is a mark on all of them. The mark is a small grey blob at the 12 o'clock position.

The mark is in exactly the same place on all the photos - it appears when using flash or not.

I have checked the lens and the camera mirror (non technical term there!)and cannot see nothing obvious that would cause the mark.

Heres a link to a couple of the photos taken to show the mark clearly.

Can anyone hazard a guess as to what the problem is please.

A blob of something on the sensor - see the dust bunnies thread. If you can clean it off, not an issue.

Hi, it could be a spot of dust on the sensor.

Dust/mark on the sensor.

Nothing on the mirror will show up in a picture as that is purely to show the image through the viewfinder and it flips up out of the way when you take a shot.

There's an option in the menus somewhere to lock the mirror up in "cleaning mode" or similar, or you could take a long exposure (but that's a bit scarier :D), to get at the CCD for cleaning.

There's a few threads about dealing with cleaning CCDs :thumbs: (I'm not going to offer specific advice because I'm not totally clue up on what would be safe objects to hand to clean with to be honest - I've got Pec pads and Eclipse fluid here from Warehouse Express)

Thanks for the replies.

I am not sure I am happy poking around inside of a camera that I have only had a matter of 2 hours.

I think I will contact the seller and see what happens.

I am extremely cheesed off !!

To be honest even new cameras often come with dust in. This is unavoidable in a system where you can remove lenses.

Why not do a mirror lock up and take a quick peak? Its a big looking bunny, it may even by visible so you might be able to blow it off.

Although dry your lips first in case you inadvertently spit all over it :D

Bullet bitten !!

Reasonably large spec of dust removed extremely carefully with a corner of a plastic bag - can highly recommend using plastic bags from now on as the dust stuck to it no problems. :thumbs:

Big thanks to you all. :notworthy

plastic bag?! :eek:

Highly recommended !!

I did do it very carefully and never actually touched the sensor - honest
