Photographers know that objects in an image at different distances are not in equally sharp focus. This is due to the optical parameters of the imaging system. Depth of Field Estimator helps you to interactively estimate this distance range for your purposes. MAIN FEATURES - Obtain the focus distribution for popular sensor formats interactively - Read quickly the hyperfocal distance for given optical parameters - Calculate circle of confusion based on final image dimensions or use a custom value - Estimate which parameters could be adjusted for your desired depth of field Feel free to contact me if you have any questions about the usage or want to give feedback. ## Key features - Interactive focus distribution estimation - Hyperfocal distance calculation - Circle of confusion calculation - Parameter adjustment for desired depth of field - Support for popular sensor formats ## Recent user reviews (10 of 39) All indexed reviews: https://appshunter.io/ios/app/depth-of-field-estimator/id1540947216/reviews.md ### 5/5 — Simple and Ad Free *2026-07-19, version 1.1.2* So good, I’m writing my first review ever. Good interface and ad free. ### 5/5 — Please Please can you restore ios12 compatibility? *2026-06-05, version 1.1.2* I have an older iPad I am trying to save from the landfill by literally dedicating it to this app. But now it requires 13 which I cannot upgrade to. Is there ANY way you could possibly restore 12 compatibility? I know, it is probably too much to ask. But thank you for such a great app all the same. It was very useful when I could use it. ### 5/5 — Easy to use, no gimmicks *2026-04-06, version 1.1.2* Tried most Of calculator apps. This one is the easiest to use and nicely visualized Dog on a colorful bar. ### 2/5 — good idea, but *2025-10-17, version 1.1.2* Your application shows that the DoF is greater on a full-frame sensor than on a crop sensor ### 5/5 — Works nicely! *2025-09-10, version 1.1.2* Simply & clear! ### 3/5 — Limited *2025-08-11, version 1.1.2* Can't handle lenses over 200 mm. That's a problem. Otherwise OK. ### 5/5 — Perfekt, dafür würde ich auch was geben… *2025-07-28, version 1.1.2* App macht genau, was ich mir gewünscht habe. Man kann die Sensorgröße wählen und alle Einstellungen einfach mit Schiebereglern justieren und sieht direkt mit einem farbigen Balken von Grün nach Rot, was passiert. Kostenlos, keine Werbung, herzlichen Dank für die Tolle App! Wo ist der Spendenbutton? ### 5/5 — Great app *2025-02-23, version 1.1.2* Really easy to use and understand. Great app where critical focus is required for front to back sharpness ### 3/5 — Neat! No Custom sensors tho *2025-02-09, version 1.1.2* Cool little app to quickly calculate DoF on the fly for splitting focus between actors. My biggest gripe with it is the lack of customizability regarding sensor sizes ### 5/5 — Simple and efficient DOF and hyperfocal calculator. *2025-01-04, version 1.1.2* The app is very easy to use. You can select the sensor size, focal length of the lens, aperture and distance of focus. You can then determine at which distance before and behind the subject things will be in focus. You also have the hyperfocal (if you set your focus manually on this distance everything will be sharp beyond that point - very useful in landscape and street photo). Definitely recommending this app. ## Frequently asked questions about Depth of Field Estimator ### What does the Depth of Field Estimator app do? This app helps photographers interactively estimate the range of distances that will be in sharp focus within an image. It takes into account the optical parameters of the camera system and sensor format to visualize the focus distribution. ### What are the main features of the Depth of Field Estimator? Key features include interactive estimation of focus distribution for various sensor formats, quick reading of hyperfocal distance, calculation of the circle of confusion, and the ability to estimate parameter adjustments for achieving a desired depth of field. ### Is the Depth of Field Estimator app free to use? Yes, the application is available for free. There are no in-app purchases or advertisements mentioned, indicating a completely free experience for users. ### Who would benefit from using this app? This app is designed for photographers, especially those who need precise control over their focus and depth of field.

(Many thanks for user request!) - Fixed an issue in the Circle of Confusion pane. It was possible that the text fields did not display a value even though the values were included in the calculation. If you like the app, I would be very happy about a rating or review. This will help to support the further development. Thanks a lot! ### 1.1.1 — 2021-03-30 Improvements: - Choose between three different calculation modes for circle of confusion (default, smart, and custom) - Parameters like sensor size and focal length are saved between app launches If you like the app, I would be very happy about a rating or review. This will help to support the further development. Thanks a lot! ### 1.1.0 — 2021-01-02 Improvements: - Adjustments to enable native Mac support (take a look at the Mac App Store) - Choose between distance values in metric or imperial units (set your preference in settings) If you like the app, I would be very happy about a rating or review. This will help to support the further development. Thanks a lot! ### 1.0.1 — 2020-12-02 Improvements: - Native iPad support added - Landscape orientation added - Additional values are now available for preselecting the focal length If you like the app, I would be very happy about a rating or review. This will help to support the further development. Thanks a lot! ### 1.0.0 — 2020-11-22 No release notes. ## Apps similar to Depth of Field Estimator | App | Rating | Price | Category | | --- | --- | --- | --- | | [Photo Friend exposure and DoF](https://appshunter.io/ios/app/photo-friend-exposure-and-dof/id1198327295) | 4.1 (9) | Free | Photo & Video | | [Mark II Artist's Viewfinder](https://appshunter.io/ios/app/mark-ii-artists-viewfinder/id711280537) | 4.8 (102) | $39.99 | Photo & Video | | [ManualExposure](https://appshunter.io/ios/app/manualexposure/id697932594) | 4.1 (12) | Free | Photo & Video | | [DOF Finder](https://appshunter.io/ios/app/dof-finder/id1441117517) | 4.0 (3) | Free | Photo & Video | | [Photographer's companion](https://appshunter.io/ios/app/photographers-companion/id1509043422) | 3.0 (2) | Free | Photo & Video | | [FF: Depth of Field Calculator](https://appshunter.io/ios/app/ff-depth-of-field-calculator/id954502014) | 4.0 (21) | $2.99 | Photo & Video | ## Related topics [depth of field](https://appshunter.io/ios/topics/depth-of-field) · [depth of field estimator](https://appshunter.io/ios/topics/depth-of-field-estimator) · [depth of field calculator](https://appshunter.io/ios/topics/depth-of-field-calculator) · [depth of field utility](https://appshunter.io/ios/topics/depth-of-field-utility) · [depth of field master](https://appshunter.io/ios/topics/depth-of-field-master) · [dof master](https://appshunter.io/ios/topics/dof-master) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
