New online tool: Depth of Field Calculator

This tool will calculate the depth of field for a given sensor or film type, aperture, focal length, and subject distance (the distance from the camera to the person or object you are focusing on). A lower number means that a large proportion of the background will remain in sharp focus and a higher number means that a smaller proportion (if any) will be in focus.

It also includes presets for popular video cameras. Selecting a preset will automatically change the sensor type to fit your camera.

We have two versions:
Depth of Field Calc (standard)
Depth of Field Calc (iPhone)

This tool was created as a result of feedback by users of our other other tools. We always appreciate feedback so we can create the best possible experience for you. Just use the feedback link at the bottom of every page to send your comments anonymously.
