Holder, adapter ring and grey graduated ND filter 55mm for Cokin-style systems - Massa

The Massa set for Cokin-style filter systems contains a filter holder, a 55 mm adapter ring and a grey graduated neutral density (ND) filter designed for landscape and long-exposure photography. The adapter ring secures 55 mm threaded lenses to a Cokin-type holder, while the graduated ND filter provides a smooth transition from neutral density to clear, allowing selective reduction of sky brightness without affecting foreground detail. The components are compatible with Cokin-style holders and enable precise control of exposure and contrast in outdoor shoots.

Advantages

This set combines an adapter ring, holder and graduated ND filter in a single kit, simplifying setup for photographers using 55 mm threaded lenses. The grey graduated ND filter produces a gradual light falloff that helps balance high-contrast scenes, especially bright skies against darker foregrounds. The holder offers stable mounting and easy insertion of the graduated filter, while the adapter ring provides secure attachment to compatible lenses. Materials and tolerances are chosen to minimise vignetting and ensure repeatable alignment.

Suitable for

• Landscape photography with high dynamic range between sky and foreground
• Long-exposure shots where controlled light reduction is required
• Outdoor scenes needing exposure balance and smoother highlights
• Photographers using 55 mm threaded lenses with Cokin-style holders

Key specifications

• Filter type: grey graduated neutral density (graduated ND)
• Filter shape: rectangular/slot-style compatible with Cokin-type holders
• Adapter thread size: 55 mm
• Transition: graduated (soft/medium edge depending on alignment)
• Primary function: selective light reduction for balancing exposure

How to use

Attach the 55 mm adapter ring to the lens front thread and mount the Cokin-style holder onto the ring. Slide the grey graduated ND filter into the holder and position the graduated transition so it aligns with the horizon or the area where exposure reduction is needed. Compose and focus the scene, then adjust the vertical position of the filter in the holder to fine-tune the balance between sky and foreground. For long exposures, verify that the filter is seated flat and secure to avoid movement during the exposure.

Usage recommendations

Use live view and exposure preview where available to check the effect of the graduated ND filter before capturing the final image. For scenes with irregular horizons or subjects crossing the skyline, slightly rotate or shift the filter to find the optimal transition placement. Store the filter flat in a protective sleeve when not in use to prevent scratches and keep the holder and adapter threads clean to ensure reliable mounting.
