ABSTRACT:
A photographic camera enables pseudo telephoto prints to be obtained from normal exposures, coded to identify a selected telephoto field. In the camera, an objective lens is adjustable to change its angular field of view within a field range having a moderate telephoto limit. A viewfinder has a finder lens which is adjustable to change its angular field of view to a plurality of telephoto fields narrower than the possible fields of the objective lens. The objective lens and the finder lens are coupled to adjust the finder lens selectively to the narrower telephoto fields when the objective lens is at its telephoto limit. Code means, responsive to adjustment of the finder lens to a selected telephoto field, encodes an exposure taken with the objective lens at its telephoto limit with indicia represeentative of the selected telephoto field. Thus the portion of the exposure covered by the selected telephoto field can be identified for enlargement to produce a pseudo telephoto print.
