1. A camera for detecting an object in a detection zone, comprising:
an image sensor having a plurality of light reception elements for the generation of image data from received light from the detection zone;
reception optics having a focus adjustment unit for setting a focal position, wherein a change in the focal position of the reception optics results in a change of an angle of incidence of the received light on the image sensor, the reception optics further comprising a pivotable deflection mirror, wherein pivoting of the pivotable deflection mirror changes the focal position and correspondingly changes the angle of incidence of the received light, and wherein the pivotable deflection mirror is positioned between a lens of the reception optics and the image sensor; and
a control and evaluation unit that is configured to set the focal position for a sharp recording of the image data of the object,
wherein the control and evaluation unit is further configured to dynamically compensate for a change in sensitivity of capturing of the image data caused by the change of the angle of incidence of the received light resulting from the change in the focal position.
