About DoFzone: Depth of Field Calc
DoFzone is a depth-of-field calculator made by a photographer, for photographers and filmmakers. Choose your camera and lens, set the f-number and distance, and instantly see how much will be in focus — in front of and behind your subject, plus the hyperfocal distance. CALCULATOR - Depth of field, near/far limits and hyperfocal distance - Angle of view, 35mm equivalent, field of view and magnification - Background blur at infinity - Circle of confusion presets (Standard / Strict / High-res) DOF TABLE - See depth of field across f-numbers and distances at a glance - Tap any cell for details and apply it to the calculator FORMAT COMPARISON - Compare full frame, APS-C, Micro Four Thirds, medium format and large format - Find the focal length and f-number that give the same look on another format LENS & CAMERA DATABASE - Over 1,500 lenses and 460 cameras, including older models and cinema cameras - Minimum focus distances for almost every lens - Favorites and My Gear: keep the cameras and lenses you own (or used to own) one tap away - Add your own custom lenses LiDAR MEASURING (in-app purchase) - Tap any subject on the camera view to measure its distance - Adjust the f-number while measuring and check the depth of field on the spot - Set a target depth of field to see the f-number you need - Measure the length and depth of objects, and find the best focus point - Show your lens's angle of view as a frame or zoom - Preview background blur live from LiDAR depth - Capture with depth data and later redo the focus point, f-number, focal length, blur and measurements - Save captures to Photos with shooting information On iPhones without a LiDAR Scanner, distances are estimates based on plane detection. LiDAR Measuring is a one-time purchase. All other features are free.
