Hyperfocal Calculator

Use the "Hyperfocal Calculator" mode to compute an F-number required for a desired hyperfocal distance, or compute a hyperfocal distance from a desired F-number.

Computing an F-number required for a desired hyperfocal distance

1.Switch your Promote Control to the "Hyperfocal Calculator" mode.

2.Set the desired hyperfocal distance.

3.Choose your lens focal length from the list. If your lens' focal length is not in the list, choose the closest higher focal length from the list.

4.Choose your camera sensor crop factor from the list:

• 2x - for Four Thirds standard cameras.
• 1.6x - for Canon DX cameras.
• 1.5x - for Nikon DX cameras.
• 1.3x - for Canon 1D series cameras.
• 1x (FF) - for full frame (35mm) cameras.
• 645 - for 6x4.5cm medium format film cameras.
• 6x6 - for 6x6cm medium format film cameras.
• 6x7 - for 6x7cm medium format film cameras.

The required F-number is updated to reflect your settings. If specified settings require an F-number beyond F/32, "32+" will be displayed for the F-number.

Computing a hyperfocal distance from a given F-number

1. Choose your lens focal length from the list. If your lens' focal length is not in the list, choose the closest higher focal length from the list.

2. Choose your camera sensor crop factor as described above.

3. Choose a desired F-number from the list. If the desired F-number is not in the list, choose the closest lower number from the list.

4. The resulting hyperfocal distance is updated to reflect your settings.
You can choose the distance unit to be meters, feet, or yards using the "Distance units" Setup setting. See Setup Menu section for more information.
