What Is Hyperfocal Distance?
The technical definition of hyperfocal distance is simple. It is the closest point where you can focus while keeping the distant background acceptably sharp.
In other words, hyperfocal distance helps you create the greatest possible depth of field in a landscape photograph.
When you focus at the hyperfocal distance, everything from about half that distance to infinity should appear acceptably sharp.
For example, imagine the hyperfocal distance is 10 feet. Focus on a point 10 feet from your camera. The scene should then appear sharp from about 5 feet to the distant background.
Three factors affect depth of field: aperture, focal length, and the distance between your camera and the subject. We covered these factors on the previous page. However, we can also review them together if you need help.
Now, let’s dive in so you can get outside and start capturing amazing landscape photographs.

How Do You Find the Hyperfocal Distance?
You need three pieces of information to calculate hyperfocal distance:
The focal length of your lens
The aperture, or f-stop
The circle of confusion for your camera
The formula looks like this:
Hyperfocal Distance = Focal Length × Focal Length ÷ Aperture × Circle of Confusion
You may be thinking, “I thought this was supposed to be easy. Now I have to do math in the field?”
No, thank you!
Fortunately, you do not have to calculate it yourself. Math is not my forte either.
You can find hyperfocal distance charts online. Simply print one and keep it in your camera bag. I have also included a chart on the last page.
In addition, several photography apps can calculate the distance for you. I use the PhotoPills app.
To use the app, enter:
Your camera body
The focal length of your lens
The aperture you plan to use
PhotoPills automatically selects the standard circle of confusion for your camera. It then calculates the hyperfocal distance for you.
See? I told you it would not be so bad.
