Massa filter adapter for Cokin system, 82mm (SB796)

The Massa filter adapter for Cokin system, 82mm (SB796) is an adapter ring that enables lenses with an 82mm filter thread to accept Cokin-style square and rectangular filter holders. It screws onto the lens' 82mm thread and provides the standard Cokin mounting slot for holder panels, allowing use of graduated neutral density, solid ND, color or special-effect filters in front of a compatible lens. The adapter is intended for photographers who need to combine the optical characteristics of their lens with the flexibility of holder-based filters, particularly in landscape and architectural applications.

Advantages

The adapter provides a secure mechanical connection between an 82mm threaded lens and Cokin filter holders without modifying the lens. It preserves access to the full filter panel range designed for the Cokin system and supports quick insertion and removal of filters. The product is compact and lightweight, minimizing additional bulk on the lens while maintaining alignment of filter panels for consistent framing and exposure control.

Suitable for

• Landscape photography requiring graduated neutral density or polarizing arrangements
• Architectural photography where control of sky brightness and reflections is needed
• Long exposure work using solid ND filters on lenses with 82mm threads
• Photographers who own Cokin-style filters and want to use them on 82mm lenses

Key specifications

• Mount thread size: 82mm screw-in
• Compatibility: Cokin-style square/rectangular filter holders
• Material: durable metal construction with precise threading (material type may vary)
• Finish: matte or anodized surface to reduce reflections
• Fit: designed to align standard Cokin filter panels securely in front of the lens

How to use

Screw the adapter onto the lens' front 82mm filter thread until it is hand-tight and properly seated. Slide the Cokin filter holder onto the adapter's mounting slot and secure it according to the holder's fastening method. Insert the chosen filter panel(s) into the holder slots, adjust the position of graduated filters as needed for composition, and confirm there is no vignetting at the chosen focal length and aperture. Remove by reversing the steps: slide out filter panels, detach the holder, and unscrew the adapter from the lens.

Usage recommendations

Check for vignetting with wide-angle lenses when using multiple filter panels; test the combination at typical shooting apertures. Keep threads and mounting surfaces clean to ensure a secure fit and to avoid scratching filters. When shooting near bright light sources, verify that the adapter's finish does not cause unwanted reflections into the image.
