SW150 mkII Adapter for Sigma 14mm f/1.8 DG Art lens
Adapter ring
The Lee SW150 mkII Adapter for Sigma 14mm f/1.8 DG Art lens is designed to allow a separately available SW150 Mark II Filter Holder to connect to a Sigma 14mm f/1.8 DG Art lens. This allows 150mm-wide, 2mm-thick filters to be used without vignetting.
It is built with three different ring components - a front ring, a compression ring, and a locking ring. The front right slides easily over the built-in hood on the lens, and the compession and lock rings slip over the rear of the lens until they meet the front ring, where they can be attached to each other.
