I bought an adapter that mounts between the lens and camera. It tilts up to 8 degrees then you can rotate it 360 degrees to tilt in any direction. It allows you to change the plane of focus. The lens will not focus to infinity with the adapter-only good for macro photography. Here's two shot with and without tilting at the same f stop. Tilting allowed me to get the whole watch in focus. But it doesn't work for 3 dimensional subjects. If the watch was really thick, the top or bottom would be out of focus after tilting.
