The Zuiko 4cm f/2.8 is the only lens made by Olympus in Leica screw mount. At about the same period, Olympus was also selling a Zuiko 4cm f/3.5 for Exakta.

Description
The Zuiko 4cm f/2.8 has five elements in four groups (three separate elements at the front and a cemented doublet at the rear), and is said to be the same as the Super-Zuiko 4.0cm f/2.8 made for the ill-fated Olympus 35 II.[1]
The Leica mount lens has a rigid all-chrome barrel with a focusing tab and an infinity stop. It takes half a turn to focus down to 3.5ft. The aperture scale is graduated to f/16. The back of the lens mount has the word JAPAN and a number whose meaning is unknown.

Total production and variations
All the lens numbers observed so far are in the 60xxx and 61xxx range,[2] for a total production comprised between 1,600 and 2,000.
An advertisement by Olympus, published in the May 1950 issue of Asahi Camera, shows an early example, with Olympus Zuiko Coated 1:2.8 f=4cm No.60234 on the front rim.[3] The marking soon became Olympus Zuiko C. 1:2.8 f=4cm No,xxxxx with a red C.[4] It became all black on the late lenses — the transition occurred around lens no.61500 and perhaps indicates that a new batch was launched.[5] (These marking changes parallel those of the Zuiko 7.5cm f/3.5 mounted on the Olympus Chrome Six.)
It is said that the lens was also advertised by Shōwa Kōgaku, the maker of the Leotax.[6] It was still available in October 1955 for ¥12,000, but was certainly no longer produced.[7]

The dedicated finder has an accessory shoe on top; the side has the OLYMPUS OIC logo and the focal length 4 cm. The original front cap is all chrome and has the OLYMPUS OIC logo stamped on it. The rear cap is all chrome too and is sometimes marked MADE IN OCCUPIED JAPAN. The leather case has the OLYMPUS OIC logo at the top and a compartment inside for the finder. The bottom of the case is embossed "MADE IN OCCUPIED JAPAN", at least on some occasions.
