ABSTRACT OF THE DISCLOSURE A first scale component is stationarily mounted on a stationary lens component relative to which a rotatable lens component is supported. A pointer is supported from the rotatable lens component for angular displace- ment therewith and the first scale component includes first linear lens stop scale indicia thereon relative to which the pointer is registered and along which the pointer may swing. A second scale component including a second linear size compensation Scale is provided and supported from the second scale component for back and forth shifting relative thereto for longitudinal- ly shifting of the size adjustment scale generally along the path of swinging movement of the pointer. A third scale component including a third linear density value scale is supported from the first scale component for back and forth longitudinal shifting of the density scale transverse to the longi- tudinal extent of an adjacent portion of the size component scale.
