How focus distance affects Depth Of Field

The main thing to understand about the focal distance is that as you focus closer to the camera, that is, if your subject is closer to the camera, the shallower, the narrorwer the depth of field will be. As you focus farther from the camera, moving your subject away from the camera, the larger, or greater the DOF will be. 

Another good thing to know, is that every lens has a point at which if you focus far enough away, the end of the dof drops off into infinity, we call this the hyperfocal distance. This means that if you have an app or book to show where the hyperfocal distance starts for your given lens and settings, you won't need to set your lens to infinity to get that landscape shot.
