Filter adapter Massa for Cokin system, 67 mm thread (SB618)

The Massa filter adapter for the Cokin system with a 67 mm thread allows photographers to attach a Cokin-style square or rectangular filter holder to lenses that have a 67 mm front thread. This adapter creates mechanical compatibility between the lens thread size and the Cokin filter holder, enabling the use of graduated, neutral-density and other panel filters without modifying the lens. The design is compact and intended for stable mounting when composing landscape, architecture and long-exposure images.

Advantages

The adapter provides a secure and straightforward connection between a 67 mm threaded lens and a Cokin filter holder, simplifying filter changes and alignment. It preserves access to standard screw-in accessories on the lens while enabling the broader range of creative control available with square and rectangular filters. The adapter is lightweight and designed for easy attachment and removal, supporting quick setup in the field.

• Landscape photography requiring graduated or neutral-density filters

How to use
