Thanks for the info on the
Demystifying Sensor Cleaning link. I did wonder about particles being blown out from the Hurricane blower and landing in the sensor area.
After reading the article, it sounds like the Delkin system is pretty good except I will substitute the waterbased cleaning solution with the E2/Methanol solution as suggested for the 5D.
I did find a local camera store that has all the items cheaper than going through the Manufacturers direct.
As for Olympus? Well........ nuff said.
Thanks All.
