Originally posted by cristigj --Mitigating dust on sensor: Obviously, I am quite curious about the issue of the shutter being open all the time (except when the camera is powered off or while taking a picture). Has anyone had any ways or tips to keep that sensor clean? My wife had an idea and I am curious if anyone has tried this before. Using a regular balloon, create static charge on surface of balloon, hold camera upside down with shutter open (barrel facing down), activate the in-camera shaking mechanism. Not sure if polarity of static charge can be reliably determined to attract dust away from sensor and not repel dust towards it? Other than that -- I am supposing something like the Pentax cleaning kit or the magic wand thing?
Here there are two very important advices with the K-01: (1) lens swapping and (2) in-camera dust removal tools.
(1) With the K-01, your camera must be switched off before swapping lenses. In the negative, the sensor will become dusty very rapidly. This is specific to the K-01 and does not apply to the other K- dSLRs.
(2) In camera settings: using the menu, set your camera to Dust Removal at Startup (and possibly at Shut down) (Manual P. 237). It will help. You may also do a regular Sensor Cleaning every so often.
Hope that the comment will help.
