ABSTRACT:
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. The apparatus may provide for manual adjustment utilizing a setting determined on the basis of the focus setting, aperture setting and focal length setting of the lens. Automatic compensation may alternatively be provided within the camera as changes are made in lens adjustment.
