[[Kodak]] created and constructed built eight photographic subsystems for the Lunar Orbiter program, five of which were used in space missions of 1966 and 1967.<ref name=":0" /> The camera used two lenses to simultaneously expose a wide-angle and a high-resolution image on the same film. The wide-angle, medium resolution mode used an 80&nbsp;mm F 2.8 [[Schneider Kreuznach#Xenotar|Xenotar]] lens manufactured by [[Schneider Kreuznach]] of West Germany. The high-resolution mode used a 610&nbsp;mm F 5.6 Panoramic lens manufactured by the Pacific Optical Company.<ref>{{cite web |last=Byers |first=Bruce K. |date=April 1977 |title=DESTINATION MOON: A History of the Lunar Orbiter Program |url=http://www.hq.nasa.gov/office/pao/History/TM-3487/top.htm |url-status=dead |archive-url=https://web.archive.org/web/20200411153526/http://www.hq.nasa.gov/office/pao/History/TM-3487/top.htm |archive-date=2020-04-11 |access-date=2010-12-18 |publisher=NASA}}</ref> The cameras exposed negatives on [[65 mm film|65 mm]] Kodak Bimat film, which was then developed onboard using a semidry process.<ref name=":1">{{cite web |last=Hall |first=R.
