A film pack type camera having a spacer which is removably insertible into the camera at a location to be received in front of the film, in a manner shifting the plane of the film slightly rearwardly relative to the camera lens, to thus correspondingly alter the subject-to-camera distance at which an image of the subject is in focus on the film, and thereby allow for easy and rapid, but precise, conversion of the camera between two different subject-to-camera distance conditions.
