Work out exactly how much of your scene will be in sharp focus before you press the shutter. Enter your focal length, aperture, the distance to your subject, and pick a sensor size, and this calculator returns the near focus limit, the far focus limit, and the total depth of field. It also shows the hyperfocal distance for your settings, which is the closest focus point that keeps everything from half that distance to infinity acceptably sharp. Depth of field grows with a smaller aperture, a shorter focal length, and a greater subject distance, so the numbers here help you plan portraits with soft backgrounds or landscapes that stay crisp front to back. The math uses the standard circle of confusion for each sensor format. Everything runs in your browser, so nothing you enter is sent anywhere.
