Yet you've reported quite a number of problems with your gear over the past year or so I think. I'm wondering if lens changes without first turning off the camera might have contributed to or caused some issues for you.

Perrone expressed an opinion of his. He never declared it as proven fact because it is not. Some people who note excessive dust on their camera sensors take upwards of a couple of minutes to change lenses, but later declare that they always change lenses quickly because that's their perception. Dust can get in during long lens changes. I've seen people purse their lips and blow dust from around a open lens mount on the camera and then afterwards state absolutely that they would never do such a thing because they simply did it without thinking about it much less remembering afterward that they'd done it.

Somebody might want to actually put a meter on the body mount lens contacts to confirm that. Declaring it as fact without some sort of actual proof might be a bit imprudent.

Wrong. Turn camera off. Remove lens. Turn camera on. Lock up mirror for cleaning. Remount lens when finished cleaning. Turn off camera.
