Learn the why behind it. One-time unlock, no ads. DoF Calc is a focused, good-looking depth-of-field and hyperfocal calculator for photographers and learners. Enter your focal length, aperture, focus distance and sensor format, and instantly see the near limit, far limit, hyperfocal distance and total depth of field. THE DIFFERENCE: A LIVE CLARITY BAND Most calculators just print numbers. DoF Calc shows you a live clarity band styled like the depth-of-field scale engraved on a manual lens barrel. The green in-focus zone redraws in real time as you slide focal length, aperture or distance, with a focus marker, a hyperfocal H tick, and f-marks that spread apart as you stop down. It is the headline visual that makes depth of field click. LEARN AS YOU GO Built-in plain-language explainers cover depth of field, hyperfocal distance, circle of confusion and diffraction, surfaced right on the main screen. A calculator that teaches, not just computes. FREE - Full depth-of-field calculator: near, far, hyperfocal and total DoF - Live clarity band / lens depth-of-field-scale visualization - 16 sensor and format options: Full Frame, APS-C (1.5x and Canon 1.6x), Micro 4/3, 1-inch, Medium Format, seven phone, action and compact sensor sizes, plus 645, 6x7 and 4x5 large format - 80 real camera bodies across Canon, Nikon, Sony, Fuji (incl.

Set circle of confusion to 0.030 mm to align with common reference calculators. PRIVATE AND LOCAL Everything runs on your device. No account, no cloud, no tracking, no ads, no data collected.
