Example – Depth of Field and Focal Length

Depth of field is greatly influenced by the focal length, using a long lens, 300mm for example, means that F5.6 is like F4.0.

This photo shows this in action, the nice blurred background here is also aided by a good deal of depth in the subject as well, position yourself where you can get great depth in the photo. The depth will great enhance the depth if field.
