DSLR angle of view calculator

Calculate the angle of view for a DSLR camera based on lens focal length and sensor size

Input Parameters

Calculation Results

Calculation Formula

Angle of View (degrees) = 2 * arctan(sensor width / (2 * focal length))

Where:
- Focal Length: Distance from the lens to the image sensor
- Sensor Width: Width of the digital sensor
- Sensor Height: Height of the digital sensor

DSLR angle of view calculator Calculator Usage Guide

Learn how to use the DSLR angle of view calculator and its working principles

How to Use the Calculator

  1. Enter the focal length of your camera lens in millimeters (mm).
  2. Enter the width of your camera's sensor in millimeters (mm).
  3. Enter the height of your camera's sensor in millimeters (mm).
  4. Click the "Calculate" button to compute the horizontal and vertical angles of view.
  5. The results will be displayed in degrees.

Understanding the Results

The horizontal angle of view is the angle across the width of the image, while the vertical angle of view is the angle across the height of the image. These values help you understand how wide or tall the field of view is for your camera setup.

Example

For a DSLR with a 50mm lens and a full-frame sensor (sensor width: 36mm, sensor height: 24mm):

Focal Length: 50mm

Sensor Width: 36mm

Sensor Height: 24mm

Calculating these values will give you the horizontal and vertical angles of view, which can help you plan your shots and understand the coverage of your lens.

Common Use Cases

  • Planning landscape photography shots
  • Understanding the field of view for wildlife photography
  • Calculating the needed lens for specific subjects
  • Comparing different lenses for the same camera
