FocusFinder calculates the near and far end and the length of the sharp range, as well as the hyperfocal distance, and visualizes them for you.
Additionally, it calculates how blurry objects at certain distances will become, and shows you the size of the blur circles.
Input is quick and easy, with perfect controls for every value.
Use the sliders, tap the side-buttons for a quick +/- 1m, or use manual entry — it's up to you.
Our beautiful background images allow you to immediately get a feeling for the different distance ranges. This helps you develop an intuition for the depth of field right away.

FocusFinder includes a huge database of modern cameras, which we update constantly. If your camera is not yet included please drop us a hint, and we will add it within a business day.
Choose any cameras as favorites to switch quickly between them.
Presets allow you to save settings you use often. You can activate them with a single tap.
If you crop your images after taking them, other depth-of-field-calculators give non-sensical answers. FocusFinder includes three precision modes that allow you to tailor your results to your use case: standard, high-definition (for light crops) or pixel-perfect.
Depth of field is the distance around the distance your camera is focused where objects appear acceptably sharp in an image.
E.g., in the image above, the depth of field is around half a centimeter - the wasp is fully sharp, but everything behind or in front of it is blurred.
FocusFinder shows your depth of field with a delta in front of it.
These are the distances from your camera where the depth of field begins and ends. E.g., every objects that is at least the "near" distance away from the camera and at most the "far" distance away appears sharp.
In landscape shots ("landscape" as in "nature", not as in "landscape mode") you often see an infinite depth of field - everything after a certain distance will appear focused. You can achieve this by setting your camera's focus to the hyperfocal distance that's calculated by FocusFinder.
If you want to set an exact value for those values, you can use one of several methods:
First, you can drag your finger down while setting a value on the slider, like in the videos-app. This will increase the precision of the slider.
Second, you can use the buttons directly left or right of the slider to make quick +/- adjustments. This will smartly switch to the next unit, e.g. from 3.6 to 3.7m or from 400 to 410m.
The distance can also be set manually by tapping the keypad-button next to "distance", and then inputting your desired value.
You can use the distance slider to set the distance that your lens is focused to, in order to calculate the area of the image that will be in focus. If you usually set your lens to the hyperfocal distance, you can use FocusFinder's Hyperfocal Mode, which will disable the distance slider and use the calculated hyperfocal distance instead.
To add a preset, input the settings you would like to save and tap the plus button right next to the presets. Tapping on the preset will then set your controls to this values again.
To change or delete a preset you can long-press on the preset, and choose from changing or deleting it.
FocusFinder has a huge included database that is updated constantly. If your camera is not supported yet, please mail us here (or use the feedback form inside the app), and we will add it.

Yes. We have tested the calculations thoroughly. FocusFinder might, however, give slightly different results for some cameras compared to older approximative formulae. This is because FocusFinder calculates the maximum Circle Of Confusion for your camera's sensor, instead of using a generic estimate (like 0.03 for full-frame-cameras). This results in more accurate results for your camera. If you prefer a circle of confusion of 0.03, use the supplied "Generic Full-Frame"-camera from the database.
That being said, if you do discover inaccurate calculations, please tell us with the feedback form, and we will be glad to help you.
We value your privacy. We do not collect your data, with two simple exceptions:
