Let me introduce you to the NiSi S6 150mm Filter Holder Kit with Landscape CPL for Canon 17mm TS-E F/4.
One of the first of the new NiSi S6 range designed for ultra wide-angle lenses without a standard filter thread. The S6 holder is part of 150mm wide filter system. The use of filters of such a large size is necessary with ultra-wide angle lenses to avoid vignette. The S6 is beautifully designed for durability. The main adapter ring, features an aluminum alloy construction and allows a very quick installation and removal without removing the lens from the camera. Also the S6 allows the use of an integrated Landscape CPL and two 150mm wide filters (2mm thick) with 360 degrees rotation for the Polariser and the main Holder. One of the many advantages for the S6 over other solutions for the 150mm system, is the possibility of screwing the CPL polariser directly into the main adaptor ring, and its rotation with the use of two wheels located on it, it will ease the Polarisation process. This great solution is known to the users of the V6 holder for the NiSi 100mm system, and now it is also available for the 150mm system. The S6 features a new locking system to lock the main filter holder in position and the integrated wheel can be easily rotated to lock the holder in place with a locking system that feels natural and easy to use.
This is my own impressions of the S6 tests with the Canon TS-4 F4 lens together with Canon 5DMK4.
NiSi has got its users used to the fact that their products are of the highest quality. The holder with the ring and polariser are packed in a thick-walled pouch, carefully sewn from nicely modern material. The main compartment is for the holder and the ring, and the front smaller pocket is for the polariser CPL. The packaging has a strap to help attaching the pouch to the tripod. The whole kit looks very good, all the elements fit perfectly. There is no room for compromise here.
The Landscape CPL
NiSi S6 Landscape NC CPL for S6 150mm holder is an ultra HD polariser designed to eliminate reflections and glares effectively when using ultra-wide-angle lenses. Is made using Nitto polarising film and increases the saturation of the scene. The Landscape CPL provides maximum polarisation of 99.9% that emphasises the natural colours of the scene and has a greater haze reduction effect.
A geared design allows the integrated CPL to be rotated while using 150mm filters using two wheels located on the side of the main adaptor, a design feature taken from great V6 100mm holder. The holder allows a very quick installation and removal without removing the lens from the camera. The front of the holder with clips holding the 150mm filters can be rapidly removed to allow focus and easy replacement or removal of the filters.
The main 150mm holder
The S6 has an updated design based on feedback from users over the S5, the design of the front filter holder has been refined to make it easier to insert and remove ND and GND filters. A new integrated locking system to lock the front filter holder is also added and a new matting treatment on the inside of the adaptor to reduce reflection, ghosting, and flare is the icing on the cake. All of this new improvements looks and works perfectly.
The holder is mounted on the same principle as in the 100mm system – by pulling back a small metal pin . A novelty on the 150 mm system is to use a polariser filter and up to 2 additional filters at the same time. The holder has two slots allowing the use of two square filters and a polariser. The biggest advantage of the S6 is the ability to rotate the polariser with the aforementioned wheels, regardless of the rotation of the holder with GND or ND filters inserted! The filters move with adequate resistance on the holder, which is particularly well visible in the video at the end of this article. Thanks to this, there is no fear that the heavy glass filter will come out of the holder when carrying the camera or in a strong windy situation.
The Holder S6 is a great addition for fans of wide-angle lenses. The biggest advantage of the S6 is of course the ability to use a polariser, a GND and ND filters together. All the elements are quite large: the polariser itself is 14.8cm. However, the whole thing is made so modernly that we do not have the impression that we are lugging unnecessary lumber into the open air. For those who hesitate to enter the NiSi 150 mm system, I recommend the S6 holder! NiSi system has some noticeable improvements over the other filter system I used in the past. First of all, the built quality is better, which is certainly a big advantage. Especially with the carrying case, the NiSi system feels more complete. But more importantly, the polariser filter strongly favours NiSi. There aren’t huge differences between the other brands I use, but NiSi just makes our lives a lot easier when we need to use a polariser and a grad filter at the same time (which happens relatively often for our landscape work).
