Hi, Scott and all.

A possible explanation would be the *effective* aperture on the lens. Dust
on sensor will show only at small apertures, and when doing extreme macro,
the *effective* aperture may be much smaller (higher f-number) than the
setting on the lens.
My 300D has also a dusty sensor :-( but is only an issue from f/16 and
beyond, which I rarely use.
Hope this helps,
