Julie, In actuality I left my thinking cap off. When I was experimenting with some other of my wife's jewelery and could not get the DOF I wanted (I had it set on f/25) and never changed it for the coin shot. The DOF for a Macro lens is extremely shallow so I just make sure and crank the f/stop usually near its limits. I could have gone to f/32.
