Calculate the field of view using sensor size and focal length. Get the result in degrees.

Calculate Field of View

Purpose

The purpose of this function is to calculate the Field of View (FOV) which is the maximum area of a scene that can be captured by a camera sensor. The FOV is determined by the sensor size and the focal length of the lens.

Use Cases

This function can be used by photographers, videographers, and anyone working with cameras to determine the angle of view that their camera setup will capture.

How to Use

1. Enter the sensor size and focal length values in the respective input fields.
2. Click on the calculate button to get the result.

Input Values

1. Sensor Size: The size of the camera sensor. Default unit is inch.
2. Focal Length: The focal length of the lens. Default unit is inch.

Output Values

1. Field of View (FOV): The calculated field of view in degrees.

Any other Instruction

Make sure to enter the correct values for sensor size and focal length to get an accurate result.

Steps of Calculation

1. Calculate the FOV using the formula: 2 * atan(sensor_size / (2 * focal_length))
2. Convert the result to degrees.

Technical Parameters

sensor_size, focal_length

Return Values

Field of View (FOV)

Example Expressions

You can use the following expressions to directly evaluate in a non-interactive manner using eva():

eva(field_of_view(sensor_size='36 mm', focal_length='50 mm'))
eva(field_of_view(sensor_size='24 mm', focal_length='35 mm'))
