The NiSi S5 Adaptor Only for Sigma 20mm 1:1.4 DG Art Series is an adaptor designed to custom fit the Sigma 20mm 1:1.4 DG Art Series to be used with the S5 Filter Holder (Sold separately). The adaptor is constructed with aluminium alloy utilising CNC technology. It allows the use of an integrated Circular S5 Filter (Sold separately). If you already own the S5 System you can purchase this additional adaptor to make your holder compatible with the Sigma 20mm 1:1.4 DG Art Series.
The S5 system uses an adaptor system so you can change the adaptor to make your S5 holder compatible with other lenses.
A geared design allows CPL (Sold separately) to be rotated using two gear located on the rear of the holder, a design feature taken from our leading V5 Pro holder. The adaptor allows very quick installation and removal without removing the lens from the camera.
Please note this is the adaptor only and is compatible with the Circular S5 filters and requires an S5 Holder to work with 150x150mm or 150x170mm filters.
