This LEE Filters SW150 Mark II Lens Adapter is specifically designed for connecting a Canon TS-E 17mm f/4L tilt-shift lens with a separately available SW150 Mark II Filter Holder. It enables the use of 150mm-wide, 2mm-thick filters without any vignetting.
The lens adapter consists of three components: a locking ring, a compression ring, and a front ring. To attach it to the lens, simply slide the locking ring over the front of the lens and past its front element. Then position the compression ring along the lens' front. By moving the locking ring forward, it can be aligned with the compression ring. Finally, place the front ring over the lens' front and screw it onto the locking ring. With this setup, you can now attach an SW150 Mark II Holder to the front of the lens for your photography needs.
