SW150 Adapter for Olympus 7-14mm Pro f/2.8 lens
Adapter ring
The Lee SW150 Adapter for Olympus 7-14mm Pro f/2.8 lens is designed to allow a separately available SW150 Mark II Filter Holder to connect to an Olympus 7-14mm Pro f/2.8 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 on the lens, and the compression and lock rings slip over the rear of the lens until they meet the front ring, where they can be attached to each other.
