LEE Filters SW150 Mark II System Adaptor for Sigma 20mm f1.4 HSM Art Lens
The Adaptor consists of a front ring, a compressor ring and a locking ring specifically designed for the Sigma 20mm Art lens.
The SW150 Mark II Holder fits to the lens via a lens Adaptor that needs to be purchased separately from the filter holder. Each Adaptor consists of a front ring, a compression ring and a locking ring that have been specifically designed for each particular lens. When fitted, they form a collar that remains on the lens at all times.
LEE Filters are working on Adaptors for additional ultra-wideangle lenses so check back if your lens isn’t yet listed.
Please note that due to the physical size of this lens, and the extremely wide angle of view, the SW150 filter holder will vignette (or rather, the filter guides intrude into the edges of the image) at the widest angles. To avoid any vignetting we recommend using a minimum focal length of 13.5mm when using the filter holder with two filter slots and 12.5mm when using the holder with one filter slot.
