Additional information:

The Olympus Zuiko Auto-S 40 mm f/ 2.0 is a normal prime lens for 35 mm Olympus OM SLR cameras.

The Zuiko 40/2 has a very interesting and intriguing history. The lightest and smallest lens in the system became popular first with photojournalists and then with lens collectors.

The successful and very compact Zuiko  38/1.8 lens was specially designed for the Pen system. Yoshihisa Maitani designed both systems. He conceived the same compact lens for the OM system as well, but the company management and his colleagues objected to this project, considering it unviable. However, Maitani had his way and the compact lens was released. Other manufacturers' analogous lenses employ, as a rule, the Tessar optical formula and have a lens speed of 2.8. The Olympus lens uses a more complex 6-element optical design to reduce chromatic aberrations. All 40/2 lenses are multicoated.

The lens has a prototype (on the black and white photo).

There is a good likelihood that the lens was manufactured from Olympus' drawings by other Japan company. This is shown by NI identification code.

The lens had not been in serial production for a long time. The total number of lenses - 10,700 pieces.

Later on the lens became a very popular with collectors, and as result its price has considerably risen.

The aperture ring has a filter thread, so the filter does not rotate on focus.
