WebThe primary variables that affect depth of field are the focal length of the lens, the aperture setting, the subject or focus distance, and a subjective factor called the circle of confusion, abbreviated as the CoC. The circle of confusion describes the image resolution needed. There are additional considerations for close up (macro) photography.
