Key DOF Concepts for Sony A7 IV Shooters
- Hyperfocal distance: Focus at this distance and everything from half that distance to infinity will be sharp — useful for landscapes and street photography.
- Wider aperture (lower f-number) = shallower DOF — portrait shooters often use f/1.4–f/2.8 to isolate subjects.
- Longer focal length = shallower DOF at the same subject distance and aperture.
- Closer subject = shallower DOF — at macro distances, DOF can be a fraction of a millimeter.
