Hey All,
Just thought I'd drop my review of the NiSi ND IR 6k 4x5.65" Filters I've been using over the last few months:

Working on productions in Scotland is challenging, even at the best of times. In this day and age, budgets are becoming tighter and crews are becoming smaller. The reality is that we are having to work longer, therefore we need to think smarter. So looking for any tools that can give a Cinematographer / Director or Photography an advantage is a good thing. But these tools also need to be reliable and trustworthy. This is where NiSi filters come in.


I will admit, when I heard of NiSi Filters, I automatically shrugged them off because I had never heard of them. They weren’t a “brand” I had heard of because they are based in China. After a few months, during a networking event, I was talking with a colleague who had used them and spoke very highly of them, so I decided to do my homework and investigate them some more. I’m glad I did. NiSi ND IR Filters are now my go to filter of choice.


Why I hear you ask? For 3 reasons and anything else they do right is just icing on the cake.

  1. Colour Reliability
This is perhaps the most important. I have used numerous other brands of ND IR filters and find that once you start to go over 1.5 of ND, you start seeing visible colour shifts, mainly towards the magenta or green. With the NiSi filters I can see none of this. From 0.3 all the way through to 2.1 I can see no visible colour shift. This is great news as I don’t have to think about changing any settings on the cameras to rectify this. That’s not to say there isn’t any. I’m not the technical, scientific nerd like some of my friends out there, but NiSi’s ultra low colour shift certainly does not wander into the need to “de-magenta” in camera. But what I do find is that I am saving time by not having to worry about what they are doing to my digital image.


With shooting in Scotland, our weather patterns can somewhat “change” with little warning. One moment, we can be shooting in direct sunlight, then next moment, it can be pouring with rain (or snow). The weather can change that quickly here. This is perhaps a great test of the NiSi ND IR Filters. It can be quite common to use the full range of filters from 0.3 all the way to 2.1 in a single day. Because of this, the colour reliability is vital. Having now used the filters on numerous short films (money is always tight on these types of productions), the NiSi ND IR Filters have performed flawlessly. I do not need to worry about having to “correct” either in camera or with my DIT, they just work the way they should.

Note: It should be noted too that they work great with the Full Spectrum OLPF by KipperTie


  1. Packaging
Okay, so maybe packaging shouldn’t be an important factor, but it shows the care and attention a company like NiSi take, when your product arrives and you think “wow, that looks and feels great!” Granted the product has got to perform and like I’ve stated above, they do.


When I got the range of filters, each one of them came in its own individually embossed vinyl case. With the magnetic flap that snaps shut, I felt confident that if I pulled the pouch out upside down, then I wouldn’t loose the filter to a millions shards of glass.


What was even more impressive was the seven slot filter case. This is totally practical if you have the full range of seven ND IR filters as it saves space. Again, the case has the magnetic flap which snaps the case shut and each filter slot is nice marketed on each side, so you know exactly which filter your using (providing you put them back in the right slot to begin with!). It is easy to take each filter in and out of the filter case even though they are tightly compacted in there for protection. If you buy the set of filters, then this should definitely be on your shopping list.

  1. Price Point
Okay, this leads us to price point. NiSi filters are cheaper than any other main brand filter on the market. Now, some people say that cheaper isn’t always better and I would tend to agree, but this is why I said that colour reliability was my number one reason for using these filters. These filters are accurate (in my opinion), reliable and trustworthy. So if they meet these three criteria and the price point is favourable to my needs, then I’m all in. A full set in the UK will set you back around £1100+VAT, that’s for the full set of seven filters from 0.3 to 2.1 plus a case. You can’t really argue at that price point.


For technical purposes, let it be said that all my tests where done using my RED Dragon with footage shot at 6K in R3D RAW. NiSi do a range of ND IR filters specifically for 6K which are the ones I use. My set of ND IR filters are the 4x5.65”.


As I have mentioned, these are just three reasons why I would recommend the NiSi ND IR Filters. But there are other reasons. I haven’t stated the Ultra Low Reflection, the Scratch Resistance technology they apply to these to protect them even further, the Oil Resistance anti Fingerprint coating. In my opinion, these are all things that make these filters even better.

If anyone is going to IBC this year, I'll be around the NiSi stand with my filters and am happy to talk to anyone about them :)
 
How is the difference to Format Hitech firecrest?

Its been a while since I used the Format filters. How do you mean, what are the differences? Do you mean in color representation?

Matthew Allard ACS did a pretty comprehensive test on them. He compared them with True NDs. Ever so slight magenta shift but it's negligible. I've ordered a set through the group buy.

It must be such a negligible magenta shift, I can't even see it. Given your working in RAW and you're going to colour grade the footage anyway... :)

They are well worth the price!!! :)

Thanks for taking the time to write a summary of your finding with these filters, Steve. I asked about this in the Formatt thread but haven't gotten an answer, maybe you can help me with this (since those filters should behave similarly due to the rare earth coating they share if I am not mistaken)?

When you use those filters with the Full Spectrum PLPF and an IR filter (720 or even better 820nm) in front of the lens do you get an a usable image? If I am reading the Formatt link correctly the Firecrest block ALL IR light, is that the case or not with your Nisi?

Cheers
David

Totally agree hence I ordered a set. Matthew's review was also very favourable.

Hi David,

NiSi IRND filters are different with Formatt's IRND, we control the infrared instead of cutting, all the way up to 1200nm is evenly through.

Best regards
Rocky

Hi Rocky,

that is very interesting, thanks for getting back to me regarding this.
Can you confirm that shooting IR with Nisi NDs behaves pretty much like visible spectrum videography in terms of how the NDs decreases shutter speed (given that you use lenses are suitable for IR)?

Having filters that work for IR and and visible spectrum would be something very interesting.

Thanks
David
