Brennweite + Schärfentiefe Rechner
Mit diesem Tool können Sie die benötigte Brennweite berechnen, um das Bild eines Objekts aus einer bestimmten Entfernung passend auf dem jeweiligen Sensor zu erzeugen.
Depth of field calculatorsThis page is useful to calculate the depth of field when using a given lens or to choose the required aperture in order to achieve a given depth of field.
The circle of confusion c is the diameter of a circle on the image plane that can be considered a single point when the image is observed (the size of the film/imager is different that the size of the print/screen. For 35 mm photography c is usually 0.025 mm, but this value depends of course on the size of the final prints.
The hyperfocal distance H is the minimum distance from the front principal plane that will appear sharp when the lens is focuses at infinity (xo = infinity).

Calculator for finding the required aperture
The maximum possible depth of field is obtained when the lens is focused one focal length f farther than the hyperfocal distance H: everything between Dn and infinity will be sharp. The value "Infinity" can be entered for Df, but since it's case sensitive it has to be typed as shown.
