The best way to go to manual mode? Put the nifty fifty on your camera, and without taking a picture, play with the dof button and see how different apertures affect depth of field. When you understand the relationship of exposure, aperture, and depth of field, you will understand the value of going manual. It's also necessary to have a lens with a wide aperture to get good dof. A zoom that only has goes to f3.5 won't give you much dof. A 50mm with f1.8 will.
Whoa SteveR! Step on the brakes! A smaller aperture (larger number) f-8, f-11 gives greater DOF. A larger aperture (smaller number) f-1.8, f-3.5 gives less DOF.
