Depth of View Calculator

Our depth of view calculator helps you find the sharp area in a photo. In photography, this is usually called depth of field (DoF).

Depth of field is the range that looks sharp in an image. It depends on your lens, aperture, focus distance, and circle of confusion. Our online depth of field calculator uses these values to find the near limit, far limit, hyperfocal distance, and total depth of field.

You can use it with many camera setups. This includes Canon, Nikon, Sony, Fujifilm, and other camera systems.

Depth of View Formula

The calculator first finds the hyperfocal distance.

Hyperfocal distance formula:

H = (f² / (N × c)) + f

Here, H is hyperfocal distance, f is focal length, N is the f-number, and c is the circle of confusion.

Next, the calculator finds the near depth of field limit.

Near limit formula:

Dn = s(H − f) / (H + s − 2f)

Here, Dn is the near limit and s is the focus distance.

The far limit formula is:

Df = s(H − f) / (H − s)

If the focus distance is equal to or greater than the hyperfocal distance, the far limit is infinite.

Df = ∞ when s ≥ H

Finally, the total depth of field is:

DoF = Df − Dn

These formulas give the core depth of view calculation used by our calculator.

Circle of Confusion

The circle of confusion, or CoC, is a key part of a depth of field calculation. Our calculator includes preset CoC values for common sensor types.

For example, the preset value for full-frame or 35mm is 0.030 mm. The Canon APS-C preset is 0.019 mm. The Nikon, Sony, and Fujifilm APS-C preset is 0.020 mm.

You can also enter a custom CoC value.

How to Use Online Depth of View Calculator

Using our depth of field calculator online is simple.

1. Enter your lens focal length in millimeters.
2. Enter your aperture or f-number, such as f/2.8, f/5.6, or f/8.
3. Enter your focus distance and select the unit. You can use mm, cm, meters, inches, or feet.
4. Select your circle of confusion preset or enter a custom value.
5. Click the calculate button. The calculator shows the hyperfocal distance, near limit, far limit, and total depth of field.

Example Depth of View Calculation

Suppose you use a 50 mm lens at f/8. You focus at 3 meters and use a full-frame CoC of 0.030 mm.

First, convert 3 meters to 3,000 mm.

Hyperfocal distance:

H = (50² / (8 × 0.030)) + 50

H = 10,466.67 mm

So, the hyperfocal distance is about 10.47 meters.

Near limit:

Dn = 3,000(10,466.67 − 50) / (10,466.67 + 3,000 − 100)

Dn ≈ 2,340.43 mm

So, the near limit is about 2.34 meters.

Far limit:

Df = 3,000(10,466.67 − 50) / (10,466.67 − 3,000)

Df ≈ 4,177.42 mm

So, the far limit is about 4.18 meters.

Total depth of field:

DoF = 4,177.42 − 2,340.43

DoF ≈ 1,836.99 mm

So, the total depth of field is about 1.84 meters.

Final Verdict

Our depth of view calculator makes camera DoF calculation fast and easy. You only need the focal length, f-number, focus distance, and circle of confusion.

It works as a useful depth of field calculator online for checking how much of a scene may look sharp. It can help with portraits, landscapes, street photos, and general camera planning.

FAQs

What is a depth of view calculator?

A depth of view calculator is commonly used to mean a depth of field calculator. It estimates the range of distances that appears acceptably sharp in a photo.

What affects depth of field?

Focal length, aperture, focus distance, and circle of confusion all affect the calculated depth of field.

Is depth of field the same as depth of view?

In photography, depth of field is the standard term. “Depth of view” is often used when people mean the same camera concept.

Can I use this calculator for Canon and Nikon cameras?

Yes. You can select the suitable circle of confusion preset for your camera sensor and enter your lens settings.

What happens at the hyperfocal distance?

When you focus at the hyperfocal distance, the calculated far depth of field extends to infinity.
