‘You press the button, we do the rest’
Some comic did a funny bit about how people act when you hand them your camera to take a picture. “What do I do? What do I press?”
IT’S THE SILVER BUTTON ON THE TOP RIGHT!!! Same place it’s been for 130 years!!!!
Not so fast, doofus.
130 years ago there was no autofocus, and correct automatic f-stop with partial depression of the dumb-button-which-has-been-there-for-150-years!
