## What is Depth of Field?

Plan focus and framing from the active sensor area. Calculate near and far focus limits, total depth of field, hyperfocal distance, angular and physical field of view, and full-frame equivalent focal length. Sensor First includes compound metric and imperial units, an offline camera and lens catalog, format matching, side-by-side setup comparison, anamorphic and optical-adapter calculations, image-circle coverage, custom gear, saved setup snapshots, and PDF, CSV, or text exports. The complete depth-of-field calculator and five generic sensor formats are free. Sensor First Pro is a one-time $4.99 unlock for the advanced toolkit. No account, analytics, ads, or network connection are required for calculations.
