[quote=Longshadow]Technically, yes it does. Just like the ignition switch on your car, wall switches, ... .
More that 1,000(
) and you'll probably replace the camera before the on-off switch goes bad.
When was the last time you had an on-off switch go bad on anything?
Pro Z9 user here.
First off, I started digital, a long , long time ago, with the D100, and I have never needed a sensor cleaning, which is testament to my careful handling of my expensive equipment
I do have a bad habit of shutting the camera off, a few dozen times during a shoot.
Early digital bodies ate batteries for breakfast.
Because of that, I developed the habit of switching it off.
I have never needed to have a digital Nikon body serviced for any reason, which is an absolutely amazing fact.
I shoot hundreds of thousands of shots a year.
Since I am shooting live music, events and weddings, etc, I am not usually in a hostile environment, no sand, no salt, etc.
I do appreciate both the sensor cover and the feature in my last few Nikon bodies, that does an ultrasonic cleaning to the sensor, on startup and shutdown, to remove dirt.
I do have the Z9 power off sensor cover, set to activate when I turn the camera off or to change lenses.
Which I do, with the lens opening facing down.
