I’d noticed on some of the test shots I did on the 30D, that there were a couple of dark patches. Very faint, but there nontheless and if you know what you’re looking for it’s very distracting – a hallmark of dust on the CCD. This isn’t something you should have on a brand new camera.
Now I’ve had my suspicions that this camera I’d bought from Leeds Jessops had been pre-owned (the seal on the box seemed to be taped back up when I bought it but I paid it little mind – lots of companies do that to check contents before selling), but this seems to confirm it. I’ve barely had 1000 pics off it and all of them have the same dusty bit.
For those of you wondering how I checked – whack the aperture right up (f28 in this case), point it at a blue sky and take a pic. The uniform colour shows the problem areas.
I’m not even going to attempt to clean it – it’s off back tomorrow.
