Ah.. So you have dust bunnies on sensor again. I’ve had this problem to, I just found a spot yesterday and blew it off using the Gitto Rocket, out of all the cleaning tools I use the rocket the most, carry on trips too. Don’t leave home with out it.

I have all the expensive cleaning stuff, sensor brushes, and sensor swabs and will some day swab my sensor. Right now I just blow of the dust bunnies off with the rocket.
I have sent my camera back to the manufacture for cleaning once and have had camera sensors
cleaned by the as part of a general maintenance, they clean the sensor on all camera repairs. The cost was from was about $60.00 I think. The results were mixed about 50% of the time it would be better and the other about the same as before. The only reason I would send it in would be if it was so serious a problem I couldn’t remove it.
Some times I don’t find the dust till after I shot the image. Then I use the healing brush in Photoshop CS2 to remove any that I find. It works great!
Here’s a Great link.
