Can you see dust on the sensor by looking at the sensor itself? It seems that I have lots of dust on mine but I couldn't see it by looking, nor is it in any way affected by blowing. I've read a lot about this but I can't tell if it's on the sensor or somewhere else (at first I had a problem with dust on the AF screen, before I knew where the sensor was). I'm not comfortable with the idea of cleaning it myself yet (I'm still too much in love with my camera to risk it ). I can't seem to see it in my pictures though, which is why I'm asking. Do you have to magnify them to more than 100%? It could be that my aperture is too wide most of the time to see it. Any ideas would be appreciated. It's not really a big thing because I did the dust delete data so maybe that's why I'm not seeing it on my pictures (DUH!!).
