System 75
For Ø 40.5mm to 67mm lens thread
It is not always easy to juggle the extensive product catalogue offered by NiSi. At the same time, it is essential to have a wide range of products to ensure good compatibility and flexibility.
By answering a series of simple questions we will guide you in choosing the perfect products for your goal.
For Ø 40.5mm to 67mm lens thread
For lens threads up to 82mm
For ultra wide angle thread-less lenses
For the Canon 11-24 F4
Screw-on Filters
Push-to-fit filters
The first thing is to check your lenses to see if a front thread is present.
If all (or at least most of the ones you want to use with filters) have front threads, you should also note the size of the threads. Usually, you will find a size in mm followed by the “Ø” symbol on the front of the lens and/or barrel.
Knowing that your lenses have threads, you can use both slot-in filters with the M75 holder (i.e. System 75) and screw filters. If you haven’t chosen yet you can consider these points:
Another important advice with the 75mm System is concerning the widest focal length available in your lenses. The M75 Holder has been designed to be compact, but we cannot guarantee that at the widest focal length there won’t be vignetting. We recommend, to be safe, to use the 75 System from 24mm equivalent full-frame focal length. This means 16mm on APS-C or 12mm on Micro Fourth Third cameras. In some situation, there are wider lenses working without vignetting (for example the Panasonic Leica DG 8-18mm f/2.8-4.0 ASPH, also called Panasonic Lumix G/Leica H-E08018) or Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH). However, we cannot advise every wider lens will work without vignetting.
If you are not sure about the widest lens you use, and some lenses are above 67mm filter thread, you’ll find our best seller 100 System the perfect holder for you.
At the bottom, in the “bonus” section (4) you will find more information about the True Color Polariser.
Knowing that your lenses have threads (up to 82mm), you can use both square filters with the 100mm holder (i.e. System 100mm), screw circular filters or push-to-fit Swift System. If you haven’t chosen yet you can consider these points:
Sony 16-35 f2.8 GM V1 – 82mm Thread
1 x Swift Filter | No vignetting @ 17mm
2 x Swift Filters | No vignetting @ 20mm
3 x Swift Filters | No vignetting @ 22mm
Sony PZ 16-35 F4 G – 72mm Thread
1 x Swift Filter | No vignetting @ 16mm
2 x Swift Filters | No vignetting @ 17mm
3 x Swift Filters | No vignetting @ 19mm
Generally speaking, circular filters are recommended for beginners who are unfamiliar with the tools, both because of the lower cost and the ease of use of a single screw-on filter. If it is you, you can go to the NiSi circular filters page.
The NiSi Swift system is particularly valuable for photographers and videographers who shoot in situations where time is crucial or where there is a need to move quickly and efficiently from one shot to another. Visit the NiSi Swift page for more informations
The square filters are perfect for those who already know how to use the polariser and ND / GND filters, as they are more flexible. If it’s you, choose the 100mm System: V7 Holder, Filter holder for specific lenses, ND 100×100, GND 100×150 or as 100mm filter Kits.
At the bottom, in the “bonus” section (4) you will find more information about the True Color CPL.
If you are here, it means that your main lens (where you want to use the filters) has a thread bigger than 82mm or does not have the possibility to screw filters in. For example, the Tamron 15-30 f/2.8 (also G2), or the Nikon 14-24 f/2.8, both F or Z mount, Sigma 14-24 f/2.8 (both for Nikon/Canon and the DG DN version for Sony), etc.
In this case, you have to go to the 150mm System. NiSi has the best 150mm Holders: the NiSi S6.
The ND and GND filters are always the same, 150x150mm (ND) and 150x170mm (GND).
The S6 holder comes with an included True Color CPL (visit section 4 for more information about the True Color CPL)
The NiSi S6 is the most advanced version for your lenses with threads over 82mm or without one. You will always find a polariser included, a bag and on almost all holders the possibility to use an adapter for other threaded lenses. In addition, we offer the possibility to buy only the interchangeable main adapter ring for those who have multiple lenses without thread.
The True Color CPL filter can be found in different models, as discussed above, such as:
The film developed by NiSi for the True Color CPL aims for maximum polarisation, uniformity and colour reproduction. Classic polarising filters are naturally subject to a yellow/green cast. Thanks to the application of the latest technologies, we have developed a polarising filter which delivers maximum chromatic fidelity, eliminating any type of colour dominance. This polariser is perfect for situations where precise colour reproduction is important.
Latest generation Cine Sealed technology
The NiSi True Color CPL uses Cine Sealing (watertight) technology that darkens and seals the edge of the filter to improve the optical performance and its lifespan
Thanks to this treatment, the influence of temperature fluctuations is reduced, condensation is prevented and the filter is protected from unwanted flare and reflections. Compared to similar treatments, NiSi Cine Sealing technology allows us to seal the edge with maximum efficiency and effectiveness.
When we discussed ND filters without colour cast in this blog, we showed the transmission curves of various ND filters showing that NiSi has the flattest curve and consequently the best colour match.
Critical to the performance of the True Color CPL is it’s uniformity of transmission across the spectrum. So rather than the absolute value of the transmission, what is important here is that the curve remains as linear as possible. A flat line across the wavelengths (nm) demonstrates that for each colour, the same amount of light is transmitted and therefore one colour does not dominate.
As we can see from this graph*, the True Color CPL polarising filter is practically perfect, with a flat and linear curve. So we can always expect accurate, natural colours.
* T% (% transmission) detected on generic polariser adjustment: the T% value varies with the variation of the light conditions and polariser adjustment, the linear behaviour of the response on the various wavelengths does not. Neutrality is therefore always guaranteed.
