I have never heard the SR function operating in my k5IIs. When the Olympus 5 axis SR is operating it can be pretty loud. In the EP5 it sounds like a small vacuum cleaner in operation. The first time I heard it, I thought it was some sort of malfunction.
Regarding my previous comment about manual cleaning of the sensor, I recall hearing/reading that you should not-as a user- take on the task of manual cleaning a sensor in a camera featuring SR/VC as the fragile components associated with the systems can be easily damaged. Conceptually, this makes a lot of sense to me. However, it does not seem to be a major bone of contention in general discussions about SR/VC on the web. I wonder if it is a significant consideration in maintenance of SR/VC cameras.
