Abstract
881,980. Lens attachment for cameras. ZEISS IKON A.G. March 24, 1960 [March 26, 1959], No. 10506/60. Classes 97(1) and 98(1). A photographic camera body has a carriage incorporating a shutter and adapted to receive a detachable lens and diaphragm unit, said carriage being movable along the camera's optical axis. In the camera shown in Fig. 1 a unit incorporating lenses 2-4 and a diaphragm 5 is attached by a bayonet joint 6 to a carriage having a shutter 8 which can be adjusted axially by spiral track means 7. A focusing lever 9 is indirectly attached to these means so that rotation of this lever will move the carriage and lens holder axially and an index 12 of a depth of focus scale is moved over a circular focusing scale 10. The scale 10 is divided into three ranges for three different units and by pressing a button 13 and rotating knob 9 a lever 15 on the knob can be engaged by any of three detents 14 adjacent the three ranges of scale 10. In another embodiment the rotation of focusing means is transmitted by means of a train of gears to a ring on the unit; said ring having the focusing scale thereon. In yet another embodiment the camera body comprises a rod which passes through the carriage and abuts one end of a rack movable on the lens unit. Movement of the carriage and lens unit during focusing causes the rack to be moved by the rod and by means of gearing a focusing scale ring on the unit is caused to rotate.
