I've owned this camera for several years and the other day I swear when I went to change the lens there was a shutter over the sensor, instead of being out in the open, then the next time I could see the sensor again. It seems like if there's a way to force that shutter down that'd be a great idea since it would keep dust from getting on the sensor but I can't seem to find a way to do this. What am I missing?Also I apologise if this has been asked and answered but search didn't reveal anything.thank you

The shutter is many times more vulnerable than the sensor as the sensor itself is protected allready sitting behind a transparent filter (anti-alias or otherwise). Simply cleaning the sensor when poluted by dustparticles should be preferred over risking damage to the shutter (while swapping lenses). Once any damage to the shutter has occured, due to what reason whatsoever, repairment will set you back atleast a few hundred dollars/euro's.

I haven't seen any command in my 6500 menu to suggest that the shutter can be closed when off. This is a new feature with the A7 IV, so I'm guessing that Sony didn't have that before.I wonder why your shutter was closed.

Feature is in the new menus.If yours was closed, there might be a problem with the mechanism.
