DOF Pro: Focus Calculator

Mihai Bold

About this app

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.

SEE WHAT STAYS SHARP
A live scene shows your settings at work. Flowers, a dog, a house and distant mountains sit at real distances, and each blurs according to your focus distance, aperture and lens. Open up the aperture and watch the background melt; zoom in and the scene tightens. You can turn the scene's animation off in Settings.

MADE FOR FOLDABLES AND TABLETS
Half-fold your phone like a laptop and the results stand up while the sliders lie flat under your thumbs. Open it like a book and results and controls each get their own half, clear of the fold. Stand it as a tent and the results face out at a glance. Layouts move smoothly as you fold, and tablets, unfolded screens and wide windows give every number room.

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.

What’s new

A whole new look, made for foldables and tablets.
• Foldables: in tabletop the results stand up while the sliders lie flat; open it like a book and each half gets its own column; stand it as a tent to read results at a glance.
• A live scene at dusk shows what stays sharp, custom sensors included.
• A big depth of field readout, focus limits at a glance and numbers that roll as you drag.
• Better tablet layouts and fixes throughout.
