NiSi True Color ND-Vario variable ND reviewed by a square filter guy

By Chris Ewen Crosby (Chris is an official NiSi USA Ambassador and reseller)

A few weeks ago I was approached by NiSi to review their new True Color ND-Vario Variable ND Filter. For those that have worked with me you might be cringing now. For those that haven’t, I’m not the biggest fan of Variable ND filters. There I said it. My past experiences with Variable ND filters have been disappointing to say the least. So when NiSi approached me to test and review their new True Color ND-Vario you can imagine that was a little bit hesitant and somewhat skeptical. Nevertheless, I accepted the opportunity to put my money where my mouth was. I’ve been recommending to my students that they stay away from variable ND Filters and it was time to test if this was still sound advice. So, do you think I can change my ways? Well, let’s find out as I share my thoughts and sample images from the test.

I wasn’t forced to NiSi products, I simply went with a superior product that turned into a great relationship with NiSi. If you are interested in hearing why I switched to NiSi please check out my blog where I’ve reviewed and compared NiSi vs other products I’ve used. So without further ado, let’s talk about the NiSi True Color ND-VARIO Pro.

Common issues that variable ND’S have

So as I eluded to in my introduction, I’m not the biggest fan of variable ND filters. My past experience with them have made me stay away from them. On of the most common things you find with Variable ND filters is vignetting as you rotate the filter to add or subtract darkness. Typically the extremes of the filters capability would produce the vignetting or what is commonly called the “X” effect where you see a dark “X” appear in the middle of your frame. They performed decently in the middle of the capability of the filter, but not at the extremes.

One of the other issues found with Variable ND filters is color cast. Often times it is a blue cast, but can also be a magenta, green, or yellow cast of color. This is something you never want in any ND filter as a photographer. You want to have the same color performance with your filters that you would have if you didn’t have them on. They should only darken your exposure and do nothing else to the image quality.

Frist Impressions

As I unboxed the ND-VARIO I was pleasantly surprised by a few things right away. The filter comes with a lens cap and a pouch in addition to a foam cushioned plastic case. That’s 3 forms of protection for your investment. I definitely didn’t get any of these 3 with my past variable ND purchases. I was lucky to get a plastic case, but most of the time you were on your own to protect and transport the filter. The lens cap is a real bonus. It can be used to cover the filter while walking between shots, or just storing the camera in your bag. No need to take off the filter and put it back on to protect the filter from scratching. This is very convenient in the field and will save you time during your workflow.

Another notable mention is the quality of the build. The filter ring is made from high quality aluminum, making it feel very strong, yet be very light in weight. The Knurled ring makes for easy gripping of the filter as your attach and detach the filter from your lens. The filter rotated very easily, but not easily enough that it would spin in a gust of wind or a slight nudge. The friction was just right.

Upon rotation I discovered another win. The ND-VARIO has hard stops at 1 & 5 Stops (Other models available for 5-9 Stops). This means that the filter does not rotate 360 degrees and there are marks on the filter ring to show you where each stop is. While the exact darkening does vary with your focal length and aperture, I found the indicated stop numbers on the ring to be with 1/3 of a stop of accuracy and spot on for most.

Bring on the images already!

OK, OK! I know by now you are ready to see some sample images. So without further ado…here they come. The first set of images were taken late afternoon in Death Valley. I thought this area would a perfect proving ground for the color and detail of the filter. Luck was also on my side due to the clouds that came into frame just before the test. Clouds are a great tool to use for testing the white balance performance of the filter. They are a neutral area during the middle of the day. For this test I used a fixed white balance of Shade so that there would be no variation in the white balance from photo to photo and we could see any color shifts that were taking place. The photos have only been sharpened, noise reduced and profile corrected. You may find a slight difference in exposure from photo to photo. Take a peak at the photos below.

After the first test in Death Valley I found that there was very little color shift. The only color shift I noticed was a extremely light shift to the yellow/red side. So little that it is hardly noticeable. Overall, I would say that the color performance was extremely good from the filter. I didn’t notice any vignetting and I was testing the 82mm version of the filter on my wide angle lens. I did notice a slight polarizing effect in the sky on the picture take at 1 stop, but it wasn’t something I was very worried about. The detail from photo to photo is perfect even at 100% zoom. To be honest, I liked the look of the badlands after putting the filter on, it did provide a very light polarization and controlled the color of the highlighted areas of the badlands.

Test #2

For a second test, to be sure that I was being fair, I went to a local location in the Port of Los Angeles next to the Vincent Thomas Bridge and took some shots during the blue hour. Not only did I think this would be a good test of the white balance, but also a better area for you to see the difference in shutter speeds and the effect it will provide. The water around the bridge was perfect for just that. Again, the white balance for test 2 was shot at a constant “shade” setting in camera to preserve the white balance integrity. See the images below.

As you can see the results of the 2nd test were equally impressive as it relates to white balance and color cast. Virtually no change in color through the photos. I will mention that both situations had changing light. The death valley scene had passing clouds changing the light and the Vincent Thomas scene was shot during blue hour so the colors were changing as was the light. Even in these difficult lighting situations the filter performed very well.

Fun Facts: Both sets of images were taken on a Canon 5D Mark IV & Canon 16-35mm F2.8ii. White balance was set to constant. No white balance adjustments were done to any photos. Very light sharpening, noise reduction, and some light exposure adjustments were made for constancy due to the changing light.

Summary of Wins for the True Color ND-VARIO Pro Variable ND

Great presentation of packaging and protection of of the filter by having a canvas case, plastic case, and lens cap for the filter

No Color Cast

Great Build with Knurled ring, aluminum frame and hard stops at 1 and 5 stops

No Vignetting during rotation and due tot he larger front threading, no vignetting even at 16mm on my 82mm lens ring

Overall, I was pretty surprised by the results of the test. I went into the test thinking that there was going to be an issue with vignetting and color as most variable ND filters have. I am very impressed by the build, color performance, and the presentation.

So, the question that some of you have probably is, “is this filter worth buying?”. My answer is yes, if you prefer circular filters over square systems, or if you are a videographer or portrait photographer. Variable ND filters are very handy for video and portrait because it allows you to adjust quickly in changing light when you are using a shallow depth of field. For those that prefer circular filters this is also a highly recommend as it performed very well. I would recommend this filter to anyone who fits those 3 categories.

Variable ND filters are something that everyone looks into when they first get into ND filters as they combine many filters into one. Traditionally that savings doesn’t mean great performance, but in this case, the NiSi True Color ND-VARIO Pro provides fantastic performance for a great value.

First Impressions with the new V7 Filter System by NiSi

By Chris Ewen Crosby (Chris is an official NiSi USA Ambassador and reseller)

In the last few weeks there has been quite a bit of buzz in the filter world over the new V7 Filter system from NiSi. I was lucky to get my hands on one just before the big release on October 1st and I’ve been using it over the past few weeks. To be honest, I really didn’t think that there was much to improve on and wasn’t expecting a new system this soon. However, after seeing the improvements that were made, I feel that the V7 has only made the best filter holder easier to use then ever.

Ladies and Gentleman, Full Disclosure

Before we begin I must first disclose that I’m now an Official NiSi Optics USA Ambassador and Reseller. So, yes, my opinions could come with some bias, but I only stand behind product I believe in. I wasn’t forced to NiSi products, I simply went with a superior product that turned into a great relationship with NiSi. If you are interested in hearing why I switched to NiSi please check out my blog where I’ve reviewed and compared NiSi vs other products I’ve used. So without further ado, let’s talk about the NiSi V7 System.

Ok, so what’s new?

As I eluded to in my introduction, I was caught by surprise by the release of the new V7 System. I was really curious as to what could have possibly been improved on since I really felt like the V6 system was perfect. Upon receiving the system I found out what NiSi improved on.

FIRST

First, the filter holder attachment and locking mechanism was combined into one. The old V6 system had two mechanisms, one to attached and secure the holder, and one to lock the filter holder from rotation around the main filter ring. While this never really bothered me, I’ve found the combination of the two into in one was convenient and sped up the attachment/locking of the filter holder. I would imagine the combination reduces the change of a mistaking the two mechanisms and a possible accident. I will mention that I really never had any issues with the V6 and mistaking the locking and attaching mechanisms in almost 2 years of use.

SECOND

The second change you’ll find in the new V7 System is how the Circular Polarizer attaches to the main filter ring. In the past, with the V6, you had to thread in the CPL to the filter ring. The CPL is very thin for these systems and can be uncomfortable to attach when you first get the system. I definitely have had a moment or two where I made sure that I didn’t drop the CPL while attaching to the V6 system. I’m pretty sure this was the feedback from several of the ambassadors as they definitely improved the attachment process in the V7. Now, the CPL attaches using a quick turn. You simply line up 3 lines that are on both the CPL and the main ring, then you simply drop the CPL into place and turn to the right to lock. I love this because not only does it speed up the application and removal process, but it also lowers the chance of a dropping accident happening. The CPL application process is greatly improved with the V7 System, but there is more about the CPL as well.

THIRD

The third change you’ll see with the V7 System is the new True Color CPL. In addition to the application process, they also changed the actual CPL. Previously you had the choice between a PRO CPL or Enhanced Landscape CPL. I had always used the landscape CPL, which had a slight blue tint to it which helped with richening the colors of skies and green plants very well. However, I found that the blues and green were maybe just a bit rich and there was a slight blue cast in terms of white balance. So, I was pleasantly surprised to learn about the True Color CPL, which is very color neutral. I had a chance to test the new CPL while I was in Colorado shooting fall colors and really liked the the color response that I was getting. I really felt like the colors were remaining constant, but the areas of reflected light were being controlled as I would want them. I’m a huge fan of this new CPL because as a landscape photographer colors are super important.

Vignetting

Since vignetting is something that you often get questions about let’s touch on this really quick. As with the V6, the V7 continues to have no vignetting at 16mm. I can fully rotate the filter holder 360° and never experience vignetting. This is a huge win when using a graduated filter as you can rotate the darkening effect of the grad towards the light making the graduation much smoother and realistic. It is also useful because you can rotate the filter holder to help block light when you are shooting in mid-day shooting conditions. Ensuring that you don’t have light leak or any lens flare is important to coming away with a clean photograph. Rotating the filter holder helps fight both of these.

Filter Rings - Comes with 4!

Once again, the V7 comes with most all the filter rings you are going to need. It comes with the main ring, 82mm, and also includes adapter rings for 77mm, 72mm and 67mm lenses. These rings sizes should cover just about all standard filter ring sizes. Any odd filter rings can be purchased cheaply so your system fits on just about any lens you buy, minus any bulbus wide angles.

Summary of Wins for the V7 System

New filter holder attachment that includes both attachment and locking mechanism in 1

Faster and easier attachment of the CPL to the main filter ring, no threading

True Color CPL for more accurate colors

Still 100% no vignetting at 16mm

My overall first impressions of the new V7 system is that NiSi has improved on V6. The new system reflects the feedback that was provided by the ambassador team. The improvements were made to make the system faster, easier and safer to use then ever. The fact that NiSi even made these improvements continues to prove to me how they are committed to providing the best product possible.

Some of you may be current V6 users and might be asking yourself, “Should I change to the V7?” I think the V6 system is still a fantastic system and wouldn’t recommend upgrading until you’ve worn through your current holder. The differences between the two aren’t vast and you’ll be fine until the time is right. For those that are new to the NiSi filter systems, then yes, absolutely, buy the new V7 system. It is by far the best filter system out there.
