Manufacturer description

This lens has the ideal focal length for portraiture. It is in a mount for 35mm single lens reflex cameras. The 105mm Komura is not only ideal for portraits but will be found useful in architectural, landscape and candid work where a focal length to fill the gap between 50mm and 135mm is needed. The 105mm f/2.5 is light in weight and produces a brilliant groundglass image that is easy to focus even in poor light.

From the editor

A Direct Mount lens that was available for a number of SLR mounts. For a complete list of cameras/mounts, please refer to the page dedicated to the W-Komura 35/2.5 lens.

Later, a version with an interchangeable mount (so called "Unidapter" system) was released.
