## What is DOF Pro?

Calculate depth of field for your camera, then save the setup for your next shoot. DOF Pro combines near and far focus limits, hyperfocal distance, custom sensors and saved configurations in one app.

ADJUST YOUR SHOT
Change subject distance, aperture and focal length with three horizontal sliders. See total depth of field and how much falls in front of and behind your subject.

USE YOUR OWN SENSOR
Choose an included camera profile or create a named camera from its active sensor width and height in millimetres. Useful for custom camera setups, drone sensors and known recording crops.

CONTROL THE SHARPNESS CRITERION
DOF Pro calculates a default circle of confusion for custom sensors. Set an optional CoC override for a built-in or custom camera, and restore its default when needed.

SAVE AND REUSE SETUPS
Save camera configurations and load them again later. Saved configurations and custom sensor settings stay on your device. Presets use the camera's current CoC setting.

WORK IN YOUR PREFERRED UNITS
Use metres or feet and inches. Camera profiles and macro, telephoto and extended distance ranges are included in the paid app.

No ads. No in-app purchases. No subscription. No sign-in required. Calculations work offline with the available camera catalog; catalog updates need an internet connection.

## Key features

- Depth of field calculation via sliders
- Save and load custom settings
- Extensive camera and lens database
- Metric and imperial unit support
- Customizable distance and aperture ranges
- Support for various film and cinema formats

### 4/5 — Best I have seen

*2022-07-31*

Was looking for DoF app and this is the best I have seen. Can you please add Nikon Z6ii/Z7ii/Z9?

### 4/5 — Nice app but needs an update

*2021-06-18*

Easy to use and well laid out. A couple of suggestions… 

Camera database needs an update - no Fuji GFX100S

It doesn’t seem possible to select a 110mm lens (Fuji GF110mm f2.0).

### 3/5 — So promising, but so annoying

*2020-01-31*

This app looks so promising: I really like the minimalist, elegant, UI. All the other DoF apps that I’ve seen apparently have UI’s designed a decade ago. Just horrible. This is a comparably elegant UI.

All that having been said, while the iPhone app seems to work OK, the iPad rendition is seriously flawed:

Bottom line, it’s super annoying that this pro version doesn’t support landscape mode on iPad. So, I’m sitting here with my iPad in landscape mode because it’s attached to my keyboard cover. But this app only works in portrait mode, so the screen is rotated 90 degrees. Lol.

It’s super annoying that this app expects me to have to disconnect the keyboard cover in order to use it. What’s worse is that the non-pro version of this supports landscape mode, but not this “pro” version. But the non-pro version of this app has a bug where you can’t see the f-stop, distance, and focal length values if your device is in dark mode, rendering it practically useless, if you use dark mode.

And if we could fix these issues, it would be really nice if it could show fractions (or decimal points) of inches. When working with shallow depths of field of nearby subjects, showing just to the nearest inch isn’t really enough. I’m trying to figure out the DoF differences in 85mm 1.4 vs 1.8, and to the nearest inch just doesn’t cut it.

So, thanks for a nice looking app, but these are fairly fundamental flaws/limitations. It would be great if you could take a look at it.

### 1/5 — Can’t change the camera and sensor

*2019-02-20, version 1.0*

Just a blank page when I set the camera & sensor even can’t see anything when I search. How can I do it?

**Developer response:** Hi, could you write to us the exact sequence where you encounter the problems from the feedback section in the settings panel of the app. We’ll sort it out for you. Thanks.
