Compatibility at Your Fingertips. The LEE SW150 Mark II Filter System Holder enriches the possibilities of using filters with your ultra wide-angle lenses. This filter holder is compatible with an endless amount of accessories, all located and listed on the left side of this page. Included with the SW150 is a soft storage pouch, and a lightshield to help prevent unwanted back reflections and create a light-tight seal for use with larger filter options.

How It Works. This holder is designed to work with select lenses, and each holder requires an adapter consisting of a front ring, compression ring, and a locking ring. These adapters are available to rent separately. When fitted, these rings form a collar that remains on the lens whenever filters are used. Filters slide into grooves on either side and may be stacked up to 2 at a time. The holder rotates for controlling polarizing and graduated ND effect.
