Abstract
The invention relates to an arrangement known generally as a PC-adapter or shift adapter. The objective is mounted on one component of the arrangement which can undergo a pivot movement relative to the image format thereby making possible the necessary movement of the objective relative to the image format. The pivot point is disposed as far as possible from the optical axis and outside of the beam pass-through opening of the arrangement.
