Tip: You do not need to keep constantly turning your camera off and on.
When it times out, it uses the same minimal amount of current as when you switch it “off”, which is not off either.
So unless you are putting it way for the day or are putting it into the bag, just leave it on and wake it up with a light touch of the shutter button when you want to use it again.
Great tip Michael.
Kudos on the Beatles reference, as well!
