The French optics firm of Pierre Angenieux was established in 1935. The company was known for the the retrofocus lens, introduced in 1950. This was a trade name for a lens design in which the focal length of the lens was less than the distance between the rear lens element and the image plane.
Angenieux began designing zoom lenses for motion picture cameras in 1957. During the 1960s, their wide angle C mount zoom lenses were often advertised in product catalogs for use with reflex and non-reflex Bolex cameras.
Angenieux 120 (f/2.2 12-120)
C mount versions of the Angenieux 120 were available that were optically corrected for Bolex reflex cameras; these were marked RX near the base. A built in geared crank allowed slow zooms, while a detachable 1" rod permitted faster zooms. The 120 used a standard Seriex IX filter and was approximately 1 pound, 12 ounces.
This is a USED lens, PLEASE NOTE: PL Mount, not a C Mount. There are signs of age, use and handling. There are marks on the barrel, however, the zoom and focus are smooth. The inside of the lens is clean and clear with only a bit of dust like all zoom lenses get sooner or later.
