When the OM-1 camera was first introduced at Photokina in 1972, it was actually called the M-1. However, Leitz had been using the M1 designation for one of their rangefinder camera since 1959, and they asked Olympus to change the name. By the time that Olympus agreed, a small number of bodies, lenses and accessories had been produced and sold with the M SYSTEM logo instead of the common OM SYSTEM logo, and these are of interest to collectors. The name change took place in January–February 1973. The following relevant M SYSTEM items are known:
For more information on the Olympus M System, see The Olympus M-1 Information Page by Mark Dapoz and Wide Angle's Olympus Catalogue by Jaap Korten (select the Collection link).
The Macro 38mm was one of the very first OM lenses, and some boxes were made with the original “M SYSTEM” designation. It is not known if any “M SYSTEM” versions of this lens were made.
The Tubes are not marked “OM”, so there cannot have been any “M” versions, but some boxes were made with the original “M SYSTEM” logo.
The first version of the Bellows, of which not many were made, has an “M SYSTEM” logo. The “M SYSTEM” logo is on the rear standard, just below the lens mount.
The Stage does not bear a system logo, so there cannot have been any “M” versions, but some boxes were made with the original “M SYSTEM” logo.
The first version of the Adapter, of which not many were made, has an “M SYSTEM” logo.
