Tilting lens system for camera - has at least one lens in sequence of lenses which can be swung about point on lens axis

摘要

A camera is equipped with a tilting lens system in which at least one lens of the first lens group (A) of a sequence of lens groups (T) is mounted so that it can be swung about a point (P) which is situated on the main optical axis (X) of the lens system. The lenses are arranged so that the following equation is satisfied:- L2/L1 = mT where mT is the lateral magnification of the lens group T, L1 is the distance between the point (P) and the first principal point (H1). L2 is the distance between the point (P) and the second principal point (H2). USE/ADVANTAGE - Lens system for cameras for producing a sharper image.
