This famous lens is one of the fastest lenses ever made, developed by Carl Zeiss for the “NASA” lunar program, later the famous cinematographer Stanley Kubrick had two of these lenses modified to mount onto his Mitchell BNC camera, and famously used them to film scenes in the 1975 movie Barry Lyndon using only the dim light of candles.
In the 1960s, NASA commissioned Carl Zeiss to develop a set of extremely large aperture lenses to capture images of the dark side of the moon in its Apollo missions. The company ended up creating 10 Carl Zeiss f/0.7 lenses. Six were sold to NASA, one was kept by Carl Zeiss, and three of them were sold to filmmaker Stanley Kubrick.
