Designed For Easy Installation. LEE SW150 Mark II w/ 82mm Filter Thread Adapter Kit consists of the Mark II Filter System Holder and the LEE SW150 Mark II Lens Adapter for 82mm Filter Threads. To attach the adapter to your lens of choice, just screw the threaded side of the adapter into the filter side of the lens. After that is accomplished, an SW150 Mark II Holder can be placed over the adapter from the front of the lens for use.

Filter Use & Durability. The lens adapter is curated from a durable aluminum-alloy construction, and extra protected by the plastic SW150 Mark II Filter System Holder. You are able to stack 2 filters at a time in the filter holder, avoiding vignetting by setting the lens to a focal length no less than 13.5mm. When using one filter, vignetting can be avoided by setting the lens to a focal length no less than 12.5mm.
