I've not seen this recommended for a number of reasons:

The high-pressure air can cause dust to move from a bad place to a worse place (as opposed to being removed altogether).
The condensation caused by the pressure drop & cooling of the compressed air causes stuff to get frosty. This should be temporary, but isn't likely to help in the short run.
You really don't want any of the liquid propellants used to create pressure in the can to stick to anything inside your camera.

Excellent. I'll go ahead and buy a lens cleaning pen. Can you please suggest one? – Pat1679 Aug 09 '11 at 13:42
