Try this: 1) Find a suitable scene that will show depth of field easily such as a long picket fence. 2) Stand at an angle to the fence. 3) Set the lens at its maximum opening (choose a standard or medium tele lens). 4) Focus on at a point on the fence about 10 feet away. 5) If you are at an angle to the fence you will notice that what you focused on, and very little else, is in focus. 6) Activate the preview feature and close the lens slowly observing the change in depth of field. As you close the lens, more of the fence will appear in focus. The field will darken as you close the lens, but, with a little practice, you will still be able to determine what is in focus and what is not.
