A Large Olympus G Zuiko 60mm f4 Prototype(?) Leaf Shutter Lens, Serial number 100001. With an unknown medium format camera fitting. Apertures run from f4 down to f32 with speeds from 1/500 to 1 second, plus T. Presumably designed for use on a camera body with built-in bellows (similar to a Rollei SL66 design) as no focus adjustment is available on the lens and with shutter speeds controlled from the camera body. Features V, X & M flash sync. Signs of light use only. With KOOD 77mm Polarizer.
