is an inexpensive and indispensable product that should be in every photographer's kit. Sensor dust is a big problem in the current crop of D-SLRs - especially showing up in macro photography, landscape photography and other photography using a tiny aperture opening or incorporating smooth, light colors such as a blue sky.
When cleaning my sensor, I prefer to use air rather than direct contact cleaning methods (which I occasionally resort to). The Giottos Rocket Air Blower uses a hand-squeeze for its very strong burst of air pressure. Air enters the blower from the bottom and exits from the top - preventing the dust you are blowing off from re-entering the blower chamber.
The Giottos Rocket Air Blower is very useful for blowing dust from a lens or filter. I recommend using a blower before using contact methods for cleaning a lens. The blower can remove particles that might scratch a lens or filter when wiping it with lens tissue or a lens cloth.
