S6; The 150mm filter holder, Redefined

NiSi S6 Holder | Polariser PRO | Sony 12-24 f 2.8

Most landscape photographers with ultra wide angle lenses dream of using ND, GND and polarising filters with their lenses to get the most out of their photography.

However, many ultra wide angle lenses don’t allow the use of screw-in circular filters or holders because the front element protrudes and the lens hood is often fixed. This prohibits the use of holder system and therefore a critical filter in landscape photography, the graduated ND, cannot be used.

NiSi have already redefined the 100mm filter holders with the market leading V6 for 100mm filter systems and the latest version V7 for 100mm filters with True Color CPL. A design innovation that allows the use of an integrated CPL filter and a maximum of 3 square or rectangular filters (100x100mm – 100x150mm).

Following the release of this system, NiSi received increasing pressure to reinvent the filter holder system for ultra wide lenses that require 150mm filters and have no front thread. The use of a circular polarising filter and 150mm filters at the same time has always been a problem. In response to demand we created the NiSi S6. This holder was incredibly well received and after record breaking sales, we have now improved on this great design with the NiSi S6.

NiSi S6 150mm Filter holder with Polariser

The NiSi S6 150mm filter holder represents the next generation of filter holders for wide and super-wide angle lenses. Included in each S6 kit is a choice of polariser, the Landscape Enhanced or Standard PRO. Find out the difference between these two filters here.

Continuing the high build quality of the S5, the S6 comes in CNC machined aeronautical grade aluminium and has a host of design and functional improvements such as:

  • Redesigned locking wheel for great security and ease of mounting/unmounting.
  • Premium grade flocking to absorb stray light and minimise reflection/glare
  • Redesigned filter slots and polariser gear wheel
  • No light leak, even without the CPL installed
  • Silver finish adaptor ring with knurled edges for grip

The externally mounted gear wheel gives you full control over the polariser, even with filters mounted. The S6 takes our 150mm series of ND and GND filters as well as the 150mm Natural Night filter.

150mm NiSi S6 Holder Kit

Each NiSi S6 kit contains everything you need to start using filters immediately; the holder has two 150mm filter slots and a main ring which is custom designed for your lens. This ring also houses the included polariser True Color. The NiSi S6 kit also includes a pouch and lens cap, so you can leave the polariser mounted and protected, as you change location.

NiSi S6 with True Color NC polariser (Nano Coating)

The NiSi True Color Polarising Filter features a unique polarising film that compensates for the colour variations inherent in all polarisers. Thanks to this treatment, developed exclusively for NiSi, we have created the most neutral polariser on the market. In addition, NiSi’s Nano Coating treatment and the latest production technologies ensure that this product can be used in film and photography.

S6 Lens Adapters and S6 Holder Frame

Here you will find the main Lens Adapter rings for the S6 (the one where the polariser is screwed on). If you own several lenses with a protruding front lens, i.e. without a thread, you can buy this adapter and use the same filter holders, polariser and filters.

Adapter Rings and accessories for S6 Holder

Use your NiSi S6 even with threaded lenses

Use these adapter rings to use your NiSi S6 also on lenses with a thread. If you have lenses with threads other than those directly available you can always use any step-up ring.
For example, if you have the NiSi S6 holder for Tamron 15-30 and you want to use it on a lens with a 58mm thread, you can take the 77mm adapter ring for the S6 holder below and then add a simple 58 to 77mm step up ring (sold by third parties). The rings for the NiSi S6 are also compatible with the NiSi S5.
