In a method for recording a sequence of images by means of a digital motion picture camera, an image sensor generates electrical signals in dependence of the exposure. At least two exposure changing devices are provided, which are configured to influence the exposure of the image sensor by a setting of a respective operation parameter. One of the exposure changing devices is provided as a variation device or can be selected as such, and a further exposure changing device is provided as a compensation device or can be selected as such. During a recording of a sequence of images, the following steps are performed: influencing the exposure of the image sensor by changing the setting value of the operation parameter of the variation device; receiving the changed setting value; determining a respective adjustment value of the operation parameter of the compensation device and outputting the respective adjustment value to the compensation device, wherein an influence on the exposure of the image sensor caused by a change in the setting value is at least substantially compensated by a change in the respective adjustment value; and operating the at least one compensation device in accordance with the outputted respective adjustment value.

A camera system includes a camera unit for capturing still or moving images of an object. The camera unit is adjustable in respect of at least one parameter relevant to the capture of the images based on a measurement signal. A measuring unit captures a distance between the object and the camera unit and includes a laser transceiver for emitting a laser signal and receiving a laser signal reflected by the object. An evaluation unit coupled to the laser transceiver provides the measurement signal. The measurement signal indicates the distance between the object and the camera unit. A lens system has at least two spaced apart lenses. The laser signal emitted by the laser transceiver passes through the lens system. At least one of the lenses is arranged in movable fashion such that the distance between the lenses is variably adjustable parallel to the laser signal transmission direction.
