I don't have the luxury of just bringing my cmaera to a photography store and was just wondering just how hard cleaning a sensor is. I haven't taken off my lens since i bought it, which has been about 9 months. Even though i haven't been switching back and forth from lens to lens i can still see some dust on my sensor in some of my pics. When i get a new lens(which will be very soon), i plan on attempting to clean the sensor. On top of knowing how to clean the sensor i was just wondering what is a good cleaning kit to buy for cleaning it.
