Abstract
The invention is directed to a combination of a viewing and/or documenting apparatus and an endoscope connected forward thereof. The endoscope can be pulled out relative to the apparatus and can be deflected at an angle if desired. A coupling is provided between the focusing position of the main objective of the apparatus and the pull-out length of the endoscope in such a manner that the intermediate image supplied by the endoscope is always focused independently of the particular pull-out length.
