This NiSi 150mm Filter Holder is designed to allow for the convenient use of 150mm-wide, 2mm-thick filters with a Sigma 20mm f/1.4 DG HSM Art lens without vignetting.

Use of the filter holder is easily accomplished by first sliding it over a Sigma 20mm f/1.4 DG HSM Art lens's integrated hood. The filter holder's screw-on locking pin helps to provide a reliable connection while the holder can be rotated 360°, permitting the use of graduated neutral density and other filters that are enhanced by varied positioning.

The NiSi 150mm Filter Holder for Sigma 20mm Art Lens is pre-installed with three pairs of filter slots, a configuration that accommodates up to three rectangular filters.
