Calculate hyperfocal distance using focal length, aperture, and image sensor size.

Hyperfocal Distance Calculator

Purpose

The Hyperfocal Distance Calculator helps you determine the closest distance at which a camera lens can be focused while keeping objects at infinity acceptably sharp.

Use Cases

• Photography enthusiasts who want to ensure sharp focus in their landscape photos.
• Professionals looking to optimize their camera settings for maximum depth of field.

How to Use

1. Enter the Focal Length of your lens (in mm).
2. Input the Aperture value (e.g., f/8.0).
3. Select your Image Sensor size from the dropdown menu (default unit is inch).

Input Values

1. Focal Length: The focal length of your lens in millimeters.
2. Aperture: The aperture value of your lens (e.g., f/8.0).
3. Image Sensor: The size of the image sensor in your camera.

Output Values

1. Hyperfocal Distance: The calculated hyperfocal distance in meters.

Any other Instruction

• Ensure to input the correct values for accurate results.
• The default unit for Image Sensor is inch, but you can choose other units if needed.

Calculation Steps

1. Calculate the circle of confusion based on the selected image sensor size.
2. Convert the focal length to millimeters.
3. Use the formula to calculate the hyperfocal distance.

Technical Parameters

• focal_length, aperture, image_sensor

Return Values

• Hyperfocal Distance

Example Expressions

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

hyperfocal_distance('50 mm', 8.0, '35 mm')
hyperfocal_distance('85 mm', 5.6, 'APS-C')
