Just playing around with the new lens! Now that it's so clear I can see all the dust on my sensor. Tried to clean it with the cleaning system built into the camera but it's not working. Called a camera shop this morning and it will cost me $75, plus be without a camera for 2-3 days (ugh). But it has to be done! I don't know how to clean it and I don't want to mess it up. Bummer!
