Filter Holder Massa SB612 for Cokin-style Square/Rectangular Filters

The Massa SB612 filter holder is an accessory designed for Cokin-style square and rectangular photographic filters. It mounts on lenses using an adapter ring and accepts multiple filter plates, enabling precise placement of graduated, neutral density and color correction filters. The holder is compatible with standard Cokin-type plates and allows photographers to adjust filter height and orientation to control exposure and color balance in landscape and architectural photography.

Advantages

The design provides secure attachment to lens adapter rings while allowing quick insertion and removal of individual filter plates. The holder supports multiple plates simultaneously, helping to combine graduated and solid filters without vignetting on many lenses. Its construction ensures stable positioning of filters for repeatable results and accurate alignment of graduated transitions.

Suitable for

• Landscape photography requiring graduated neutral density filters
• Architectural photography where control of highlights and shadows is needed
• Color correction and creative color effects with rectangular plates
• Photographers who need to swap filters quickly in the field

Key specifications

• Compatibility: Cokin-style square/rectangular filter plates
• Mounting: attaches to lens via compatible adapter ring

How to use

Attach an appropriate adapter ring to the lens thread size, then slide the Massa SB612 filter holder onto the adapter until it locks or seats securely.

Rotate or shift plates as needed to correct color or exposure. To change filters, slide plates out and replace them without removing the holder from the lens.

Usage recommendations

Use adapter rings that match your lens thread to avoid light leaks and vignetting. Start with a single filter to verify composition and exposure before stacking additional plates. Clean filters and holder slots before use to prevent dust and scratches on optical surfaces.
