Hi list, I own a 30D and have a strange problem.
It seems there is dust on my sensor (or lens but I doubt that since I have the problem with different lenses) but only when I'm using long exposure. When t<1s theres no problem but if t>1s the image is "dirty".
Also when I'm using studioflash (Elinchrom) the dirt (it looks like a worm) is visible but using my EX380 there is no problem.
I wonder how this is possible. Tnx for your help in advance.
