Abstract

The disclosure relates to a method for setting and visualizing parameters of an objective lens of a camera, in particular for focusing on a moving object, and to a system for per-forming the method. The camera is, for example, embodied as a film camera, in particular as a film camera used in cinematography. The method includes the following steps: calcu-lating a relative position and an alignment of a depth of field of the objective lens in the 3D space, observing the 3D space and/or the object with an AR display and observation de-vice, displaying the relative position and the alignment of the depth of field of the objective lens as an image in the AR display and observation device and/or displaying a focal plane as an image in the AR display and observation device, and setting the objective lens to ob-tain a desired depth of field of the objective lens.
