Pictured above: Leitz 7,5 cm Summar f/0.85, 1935-52 – the three lenses offered in one Lot represent the entire development of this remarkable design – it is the first prototype from 1935, a lens from the Spanner device from the Second World War, and the lens delivered on June 10th 1952, which is probably the last of this type.
