Is it safe and a good idea to clean DSLR lens using computer dust removal, which has powerful air pressure ?

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 9 '11 at 13:42
Here's a question that does a pretty good job handling the "how should I" part: – D. Lambert Aug 9 '11 at 14:31
