"Shutter When Pwr off" question a9 2

[allan473]

I just upgraded my a92 to firmware 2. Do I want to set "Shutter When Pwr off" to on or off to take advantage of the shutting the shutter wwhen the camera is unred off?

Do you want dust to settle on your shutter mechanism or on your sensor? To me the sensor seems much easier te clean. And the sensor cover glass can likely be replaced cheaper than the shutter assembly when damaged. Besides, dust which has settled on the shutter blades will be thrown around when the shutter actuates, possibly ending up on the sensor anyway.

I think this is a nonsense feature that was just added to prevent people from moving to Canon because those cameras have it. Some people have been calling for this feature to keep their sensors clean, not fully understanding the consequences of exposing the fragile shutter mechanism to possible harm.
