Originally posted by Ira I'm not ready to get into this yet since the camera is so new, but how do you guys have dust removal set up?
Is there a disadvantage to having it activate every time the camera powers up (possible mechanical failure), and you manually trigger it if from time to time instead?
I don't know that there's any Advantage to having it run on every startup, which mine do. I don't know because if it's working, I never see the dust that it shook off. I do know that for dust it Doesn't remove, no amount of shaking ever gets rid of it. It then requires (in this order),
A Blower clean- Rocket Blower, etc
A Dry clean- Pentax's O-ICK1 is my fav, some use the Arctic Butterfly (spinning paintbrush)
A Wet clean- Eclips 2 and Sensor swabs or similar
In 5 Pentax DSLRs, I've done a wet clean once. It didn't work, which prompted my purchase of the AB. Just slid the dust around on the sensor (and is for sale right now in the marketplace). Interim, I bought the Pentax cleaning kit, and for an invasive (touch the sensor) cleaning method, I've found nothing better. Wet cleaning should be reserved for when there is an actual chemical smudge of some sort on the sensor. Be it a watermark, finger oil from accidentally touching it, or similar. I don't know how tough the sensor cover filter really is but what you obviously don't want to do, is scratch it. They won't replace it without replacing the entire sensor ($400+).
As far as disadvantage, everything mechanical will eventually fail. I (hope) don't really think there is any real harm in letting it run on startup.
