Paper Abstract

Some ideas of design zoom lenses with removed forward entrance pupils (pinhole zoom lenses) are presented. The methodology and current status will be discussed in this paper. Number of examples illustrate approaches proposed: optical extension adapter which allows to use together a pinhole lens with fixed focal length and video-camera zoom lens to form a zoom pinhole lens; three positive components, including linearly moving collective lens to provide variable focal length.
