Komura lenses for Leica cameras, overview

The history of the Komura brand lenses is little-known. Information on the company and the lenses it produced is difficult to find online. But, many of the Komura lenses are very good, both in build quality and in optical results! This page lists the Komura lenses for Leica cameras, to facilitate finding those lenses online so you can shoot them on your Leica screw mount camera.

The company started out with making lenses for Large Format cameras. But in the 1950s they also started manufacturing rangefinder lenses for Leica thread mount cameras, and switched over to making lenses for Nikon rangefinders in the 1960s. Later, they also manufactured enlarging lenses, lenses for various medium format systems and also briefly produced lenses for various models of SLRs. Komura probably was the first brand to build a 1.4/85mm lens in Nikon F mount!

 

 

Below is a list of Leica Thread Mount lenses that probably were made by Komura. Some were simply branded as such, but others have different names.

Only in the 1960’s did Japanese companies start to brand their products, before that they were often sold under the name of the company or retail chain that ordered them from the Japanese factories.

Over time, I have owned several Komura and Acall lenses, even briefly owned the ‘Force’ lens listed above. Some I have shot, others I have only bought and sold. In time, some of the lenses listed here will have their own article in the ‘Komura Files’ on this website! Komura lenses for Leica cameras are awesome to shoot.

If you can share any information on the history of Komura as a manufacturer, or on the Leica Thread Mount lenses they produced, please list your lens specifications in a comment below and I will include it in the table on this page. Also pictures of the lenses are greatly welcomed, as are links to other websites that contain information on Komura lenses for Leica and Nikon rangefinders! Thank you! 

 
W.Komura 35mm 3.5 lens for Leica. Their most made lens it seems, but here in a much rarer brass version. The vast majority of those lenses is made in an alloy, brass ones are hard to find.
