This is a simple, intuitive, and professional depth of field calculator designed for photographers. By selecting the sensor format, aperture, focal length, and focus distance, you can quickly calculate the near and far depth of field for your shot. Tap “Hyperfocal Distance” to automatically calculate the optimal focus distance under the current settings, helping you make faster and more accurate shooting decisions. If the default circle of confusion does not meet your needs—for example, when printing at larger sizes or viewing images on larger, higher-resolution displays—you can manually adjust the circle of confusion to obtain more precise depth of field results for specific conditions. The app supports both metric and imperial units, allowing you to switch freely based on your preferences and shooting environment.
