About this tool

1
Select camera sensor
Choose your camera body or sensor size (full frame, APS-C, Micro Four Thirds, etc.) for correct crop factor.
2
Enter lens settings
Input the focal length and aperture (f-stop) of your lens.
3
Set subject distance
Enter the distance from your camera to the subject in meters or feet.
4
View depth of field
See the near focus limit, far focus limit, total DoF, and hyperfocal distance with a visual depth map.

For sharp landscapes, set focus to the hyperfocal distance - everything from half that distance to infinity will be acceptably sharp.
Wider apertures (lower f-number) create shallower depth of field - great for portraits with blurry backgrounds.
Sensor size matters: a full-frame camera has shallower DoF than APS-C at the same framing and aperture.
For macro photography, DoF becomes extremely shallow - consider focus stacking.
