Applications

Reverse anamorphic lenses are used in professional cinema projection systems to unsqueeze an anamorphically compressed image onto a wide-screen format. Unlike a standard anamorphic taking lens — which squeezes a wide scene onto standard film — a reverse anamorphic is placed in the projection path to expand the image horizontally, restoring the correct widescreen aspect ratio on the screen. Kowa has a long history supplying precision optics for 35mm and 16mm film projection, and the 30107 is a well-regarded example from that lineup, sought after by film archivists, cinematheques, and enthusiasts restoring or maintaining vintage 35mm projection equipment. The gold anodized finish is a distinctive Kowa hallmark and helps identify the era and product family of the lens.
