NiSi Filter Holder S6 Kit Landscape Sigma 20 F1.4

NiSi Filter Holder S6 Kit Landscape Sigma 20mm F1.4 – Holds Two 150 mm Filters Plus 360° Rotating Landscape Polarizer

This NiSi S6 kit is specially designed for ultra wide-angle lenses, including full-frame and smaller sensor formats. It forms part of the NiSi 150 mm filter system and ships with a tailored lens adapter plus the NiSi Landscape circular polarizing filter for use inside the holder.

Design and build

The S6 filter holder features an aluminum alloy construction with a matt finish to reduce reflections. Its octagon-design makes it easy and fast to install and unload ND filters. Furthermore, the holder includes interior flocking material to reduce inner reflections and to avoid glare in your images.

Filter capacity and arrangement

The holder accepts up to three filters at once. You can mount two 150 mm square filters (2 mm thick) in the front slots and place the supplied circular polarizing Landscape filter in a dedicated compartment behind them. This arrangement allows you to use combinations without disassembling the unit.

Polarizer control and locking

The Landscape polarizer installs in a compartment that allows 360° rotation. You adjust rotation using two small, easily accessible exterior wheels. Moreover, the turning filter holder can be locked in any position using a newly designed locking screw, so the polarizer remains steady during shooting.

Use cases and combinations

You can simultaneously use a standard ND filter, a graduated ND filter and the circular polarizing filter. This combination is particularly useful for landscape photography where controlling exposure, contrast and reflections matters. In short, the S6 handles the common landscape setup without requiring compromises.

Compatibility and adapter

The kit includes an adapter tailored for a particular ultra wide-angle lens that lacks a normal filter thread. You can exchange the adapter if you want to use the holder with other lenses in the NiSi system. Note that the polarizing filter supplied with the S6 is built to be used in the S6 adapter and cannot be mounted directly on a lens.

Also note the cross-compatibility detail: the S6 polarizer filter can be used on the S5 filter holder, but the S5 polarizer filter cannot be used on the S6 filter holder.

Landscape polarizer details

The Landscape version of NiSi's circular polarizing filter increases the intensity of polarization, offers greater haze reduction and provides a more uniform filter effect while maintaining a neutral color balance. The polarizer uses Nitto polarizing film and is positioned for demanding nature and travel photography.

Specifications

Notes and important details

The polarizing filter included in this kit is designed specifically for use inside the S6 adapter and cannot be mounted directly onto a lens. While the S6 polarizer fits the S5 holder, the reverse is not true: the S5 polarizer will not fit the S6 holder. The flocking material inside the holder reduces inner reflections to help prevent glare and unwanted artifacts in your photos.

FAQ

Question: Will this holder cause vignetting on full-frame ultra-wide lenses?
Answer: No, the S6 is designed for full-frame ultra-wide angle lenses and the product information states there is no vignetting when used as intended.

Question: Can I mount the included polarizer directly onto my lens filter thread?
Answer: No, the Landscape polarizer in this kit is built to be used inside the S6 adapter compartment and cannot be mounted directly on a lens.

Question: Can I use both a graduated ND and a standard ND at the same time?
Answer: Yes, the S6 holder can accommodate two 150 mm square filters simultaneously, enabling combinations such as a standard ND plus a graduated ND alongside the circular polarizer.

Question: Is the polarizer interchangeable with the S5 polarizer?
Answer: The S6 polarizer can be used on the S5 holder, but the S5 polarizer cannot be used on the S6 holder, so compatibility is one-way.

Question: What helps prevent internal reflections inside the holder?
Answer: The S6 uses flocking material on the inside of the holder to help eliminate inner reflections and reduce glare in your images.

If you need a different adapter for another lens, you can exchange the adapter to use the S6 holder with other compatible lenses in the NiSi system.
