About This Tool
Calculate exact near focus limits, far focus limits, and total depth of field in centimeters across any focal length, aperture, and sensor format. Features a real-time side-profile ray diagram and background bokeh blur diameter calculation.
How to Use
- 1
Choose camera sensor size (Full Frame 35mm, APS-C, Micro Four Thirds, Medium Format, Super 35).
- 2
Enter lens focal length (mm), aperture f-stop, and subject focus distance (meters).
- 3
Enter background object distance to calculate out-of-focus bokeh blur disk diameter.
- 4
Examine the interactive optical ray diagram and hyperfocal distance mark for landscape sharpness.
Frequently Asked Questions
What is Hyperfocal Distance?
Hyperfocal distance is the focus distance that yields the maximum possible depth of field, rendering everything from half that distance all the way to infinity acceptably sharp.
What is Circle of Confusion (CoC)?
Circle of Confusion is the maximum diameter of a blurred point of light on the camera sensor that a human eye still perceives as a sharp point when viewing the final printed image.
