Built for photographers, videographers and focus pullers who want a quick answer on set, in the studio, or out in the landscape.
Trusted by photographers since 2009
Simple DoF Calculator has a long history as a practical field tool, with independent mentions from photographers and photography communities.
Recommended by Square Foot Productions as a beginner-friendly photography tool for taking the guesswork out of depth of field and hyperfocal distance.
Square Foot ProductionsReal-time DoF calculations, built for the field
Set your camera, aperture, focal length and focus distance, then see the depth of field and hyperfocal distance update instantly.





How it works
Simple DoF Calculator turns optical setup choices into practical focus information before you press record or release the shutter.
Choose your camera
Select from supported digital, analog, photo and cinema camera formats so the calculation starts with the right circle of confusion.
Set focal length, aperture and focus distance
Enter focal length from 3 mm to 1200 mm, aperture from f/0.95 to f/64 and the focus distance for your actual shooting setup.
Read the focus result
See depth of field and hyperfocal distance update in real time as you adjust your setup.
Supported cameras and formats
Choose from DSLR, mirrorless, compact, digital back, analog photo and cinema formats so the depth of field calculation matches your actual camera.

Made for common shooting decisions
From shallow portraits to sharp landscapes
Use the app when the creative choice depends on focus: how much background blur a portrait will have, whether a landscape reaches infinity, or how tiny the depth of field becomes in macro work.
Guides for better focus decisions
Each guide explains a focus concept in plain language, then links it to the iPhone and iPad app when a practical calculation helps.

What is a depth of field calculator?
A depth of field calculator estimates the near focus limit, far focus limit and total range that will appear acceptably sharp for a camera, focal length, aperture and focus distance.
Learn moreWhat does Simple DoF Calculator calculate?
Simple DoF Calculator calculates depth of field, near focus limit, far focus limit, total depth of field and hyperfocal distance.
Learn moreIs Simple DoF Calculator available for iPhone and iPad?
Yes. Simple DoF Calculator is available on the App Store for iPhone and iPad.
Open the App Store listingWhat is hyperfocal distance?
Hyperfocal distance is the focus distance that gives the deepest usable sharpness for a selected camera format, focal length and aperture.
Learn moreCan I use it for video and cinematography?
Yes. Videographers, filmmakers and focus pullers can use the app to plan focus distance, depth of field and near and far focus limits before a take.
Learn moreDoes it support different camera formats?
Yes. The app includes many digital, analog photo and cinema camera formats, plus circle of confusion values for calculation preferences.
