Lee SW150 MKII Adapter Sigma 14-24mm f/2.8 Art Lens
The Lee SW150 Mark II Lens Adapter is designed to allow a separately available SW150 Mark II Filter Holder to connect to a Sigma 14-24mm f/2.8 DG HSM Art Lens, which then permits to the use of 150mm-wide, 2mm-thick filters without a vignette.
This lens adapter consists of three components, a front ring, a compression ring and a locking ring. Placement of the lens adapter onto the lens is easily accomplished by sliding the front ring over the built-in hood with the front ring’s integrated lugs positioned away from the lens body. The compression ring can then be slid over the rear of the lens until it meets the front ring. Finally, the locking ring is also slid over the rear of the lens until it can be screwed into the front ring. After that is accomplished, a SW150 Mark II holder can then be placed over the adapter from the front of the lens for use.
