AFW - Antique France Worldwide

Description

This antique optical filter features a circular black metal mount with a deep, uniform green filter surface. The item is a screw-on type, designed to fit a camera lens. On the visible edge, the inscriptions "GX-11", "49mm" and "JAPAN" are clearly visible, indicating a 49 mm diameter for attachment and Japanese origin.

The filter glass, perfectly smooth, displays a distinct green tint, typical of colored filters used in film and digital photography to alter chromatic rendering or enhance contrast depending on the film or sensor type. This type of filter is often used in black and white photography to strengthen certain contrasts or in color for creative effects.

The black metal mount has a sober and functional appearance, without any particular decoration or pattern, typical of photographic accessories from past decades. No chips, major scratches, or obvious defects are visible on the upper face and the exposed edge. The white screen printing of the technical information remains clearly legible, which facilitates quick identification of the model and diameter compatibility.

The entire filter has a satin finish, and its general condition suggests careful maintenance. The overall appearance of the object evokes quality manufacturing, characteristic of vintage Japanese photo accessories, particularly for the robustness of the mount and the clarity of the colored glass.

Condition

Used item, sold as is. The visible face shows no deep scratches or significant defects. Some micro-traces of use may be present from certain angles, without affecting functionality.

Did you know? Colored optical filters, like this green model, were essential in black and white film photography to adjust sky contrast or bring out certain textures. Green filters were particularly popular for portraiture, as they reduce skin imperfections and enhance detail sharpness.
