User reviews

Nikon Z8

Could you please add the Nikon Z8 to your camera list.

Before you buy make sure the company is still in business

I like the depth of field calculator and would give it five stars. However, the app developer’s site couldn’t be found when I was trying to ask about paying for but not receiving an add on program.

Lightning fast customer service!

After getting the DoF app, I found out that it did not list my primary cameras - Hasselblad H5D-50, Hasselblad H6D-100 and Canon R5!
Expecting the typical no-reply to a customer service inquiry, I was shocked and delighted to get an email WITHIN DAYS from Jim Chapple saying the cameras had been added. Wow! πŸ˜€
Thank you for top-notch customer service. And by the way, the app is fantastic, too!
Knowing your DoF on portrait work, especially with medium format and telephoto lenses, is of paramount importance in creating sharper images.

Clear, fast and accurate

Many apps, some costing substantially more, perform this function, however this app is berg fast and clear to use. It also displays the result in a manner that is clearly understandable.

Nice appβ€”simple, clean, effective

I thought about running DOF charts for my new Nikon Z6 using Excel. Then I found this app. For $.99, I saved several hours of work (and got an easier-to-use product). The app is simple, intuitive, yields clear results and is a very handy tool to have no further away than your phone when you’re setting up a shot. Nice job.

FAQ

What does the Depth of Field Calculator app do?

This app helps photographers understand and calculate the depth of field for their images. By inputting your subject distance, the focal length of your lens, and the f-stop setting, the app will show you the range of distances where your subject will be in acceptable focus. It also provides a visual diagram to illustrate this.

How do I use the app to calculate depth of field?

To use the app, you first select your camera model from the provided list. Then, you input the distance to your subject, the focal length you are using, and the desired f-stop. The app will then calculate and display the near and far limits of your depth of field.

Is this app free to use?

The app is free to download and use, but it offers in-app purchases. This suggests that while core functionality is available for free, some additional features or content might require a purchase.

What if my camera model isn't listed?

If your specific camera model is not found in the app's list, you can email the developer to request its addition. The developer is happy to include missing cameras in future releases. You can also manually input the Circle of Confusion value for your camera if you know it.

What are the benefits of using a depth of field calculator?

Using a depth of field calculator allows you to precisely control how much of your scene is in focus. This is crucial for creative photography, whether you want to isolate your subject with a blurred background or ensure everything from foreground to background is sharp. Understanding these settings helps you achieve your desired photographic outcome.
