Filter set Massa COKIN 2-in-1 72mm (model SB3623)

The Massa COKIN 2-in-1 72mm (model SB3623) is a filter set combining two Cokin-format filters adapted for direct 72 mm screw-in mounting. The set is designed to modify incoming light or protect the front element of lenses that accept 72 mm filters. It provides an accessible way to introduce common filtering effects while maintaining compatibility with lenses and camera systems that use the 72 mm thread.

Advantages

This filter set integrates two different Cokin-format filters into convenient 72 mm screw-in construction, eliminating the need for a separate holder for these sizes. The screw-in mounting ensures a secure connection to lenses with a 72 mm thread and reduces the risk of light leaks or accidental detachment. Filters are lightweight and compact for travel use and can remain attached on location to provide continuous protection for the front element.

Suitable for

• Landscape photography where graduated or color control effects are useful
• Portrait sessions requiring subtle light modification or diffusion
• Travel and outdoor photography for lens protection and quick effect application
• General-purpose use when a compact, screw-in filter solution is preferred

Key specifications

• Filter system: Cokin-format filters adapted to 72 mm screw-in thread
• Mount diameter: 72 mm screw-in
• Quantity: two filters in the set
• Primary functions: light modification and front element protection
• Compatibility: designed for lenses and cameras accepting 72 mm screw-in filters

How to use

Attach the filter by screwing it gently onto the lens front thread until secure; avoid overtightening. Use the appropriate filter from the set according to the shooting situation — for example, select the filter that alters color balance or reduces highlights when needed, or use the protective filter to guard the glass in exposed environments. When stacking filters, check for vignetting on wide-angle lenses and adjust composition or remove a filter if necessary. Clean filters before and after use with a microfiber cloth and proper optical cleaner to maintain image quality.

Usage recommendations

For best results, test each filter effect at several apertures and exposures to understand its influence on contrast and color. When shooting landscapes with wide-angle lenses, inspect the corners for vignetting if more than one filter is stacked. Store the filters in a padded case when not in use to prevent scratches and dust accumulation.
