NiSi S5 150mm filter holder for Sigma 20mm f/1.4 DG HSM Art, with Landscape Polariser
The NiSi S5 filter holder with Landscape Polariser NC is ideal for landscape photographers who want to combine an ultra wide-angle lens such as the Sigma 20mm f / 1.4 DG with a square filter system that allows you to use a screw-in Landscape polarising filter and GND/ND filters.
The 150mm NiSi S5 filter system is in CNC machined aluminium alloy; the 360° rotating holder allows the use of a screw-in polariser and two 150mm filters without vignetting.
An external ring that allows you to rotate the CPL polariser from the outside even with mounted filters. This unique feature of the NiSi S5 allows you to adjust the polariser with extreme precision using the external wheel, and therefore it is much more comfortable than using the 150mm square polariser of the other types of 150mm holders.
The Landscape NC polarizer, is NiSi’s Enhanced® CPL, with a maximum polarization of 99.9%* that emphasizes the natural colours of the scene. It also features Nano® Coating (NC) treatment that protects it and makes it completely water-repellent for easy cleaning. NiSi S5 Holder for Sigma 20mm f/1.4 DG Art includes the Landscape polariser in this kit, thanks to the panted design you can rotate the filter even with 2 square filters installed and remove it if necessary.
* The maximum polarisation changes from scene to scene depending on the incidence of light (position of the sun) and the framed material. In fact, the polariser has an effect only on the polarised light of non-metallic surfaces. The NiSi Landscape Enhanced® polariser, in suitable situations, reaches 99.9% polarisation. By turning it is possible to choose the preferred degree of polarisation. The NiSi Landscape Enhanced® polariser is the first choice of many professional landscape photographers.
