摘要 Apparatus within a camera for optimizing the location of the image surface of the lens of a camera relative to the image receiving surface such as film for different adjustments of the lens. A camera having an adjustable lens, nominal image receiving surface, focusing analog, and apparatus for adjusting the position of one such element with respect to the others to compensate for changes in the position of the image surface caused by adjustment of the lens to thereby place the image surface in best fit relationship to the nominal image receiving surface when correct focus is indicated by the focusing analog.
