Filter set Massa COKIN 2-in-1 for 55mm lenses, model SB3620

Massa COKIN 2-in-1 filter set for 55mm lenses, model SB3620, is a compact photographic filter kit that fits lenses with a 55 mm filter thread. The set contains two COKIN-compatible screw-on filters designed to be used on standard 55 mm threaded front elements, enabling basic filtration effects without the need for a separate holder. The lightweight metal and glass construction is suitable for travel and everyday shooting, offering quick attachment and removal for landscape, portrait and general-purpose photography.

Advantages

The filter set provides two versatile filters in a small, easy-to-carry package that attaches directly to 55 mm threaded lenses. COKIN compatibility increases flexibility when combining with other COKIN system accessories. The screw-on design minimizes vignetting on lenses with standard focal lengths, and the filters are convenient for photographers who prefer compact gear. The set supports improved control of light, color balance and subtle creative effects without modifying lens optics.

How to use

Select a filter according to the desired effect and align the filter threads with the lens front. Turn the filter clockwise until it is finger-tight; avoid over-tightening.

Clean the glass surfaces with a microfiber cloth or lens tissue before and after use to maintain image quality.

Usage recommendations

Use the Massa COKIN 2-in-1 set on lenses with a genuine 55 mm thread and verify mechanical clearance when using wide-angle lenses. When stacking filters, test for vignetting and loss of contrast. Store filters in a protective pouch to prevent scratches and dust accumulation.
