I have found “Lenspen” very effective for removing dust and even finger prints. It is a two ended pen with a microfine buffer on one end and a retractable lens brush on the other. It is available for various types of cameras, telescopes, etc. The specific “DSLR Kit” with three pens is about $12.95. Prices for individual pens start at about $8. They are available at B&H Photo, Amazon and even WalMart.
