Description

This is an exceptionally rare and ultra-fast lens: the Leitz Canada 65mm f/0.75. Lenses with sub-f/1 apertures are extremely uncommon and typically designed for highly specialized applications, often scientific or medical imaging, rather than general photography. This lens was likely produced by Ernst Leitz Canada (ELCAN) for Picker X-Ray Corporation, presumably for capturing images from X-ray screens or similar low-light fluoroscopy applications. Its optical design would be optimized for a specific conjugate distance and potentially a specific wavelength range. The mount is likely proprietary or specific to the imaging equipment it was designed for. Its value is extremely high but primarily to collectors of rare optics or specialized imaging historians.
