I like the filter cap. If you want to use it with the prong installed, wouldn't it be possible to cut a small notch in the edge of the cap to allow space for the prong?
Thanks for the informative review, Emil. I have 2 small questions: 1. At 3:31 you mentioned that it's still a polariser, so just wanted to understand if that's the case with only this filter or is this like generally for all VNDs? 2. Does the polarising effect decrease from 1 stop to 5 stops? I noticed on the front of the lens that it was maximum at 1 stop and it got back the reflection at 5 stops.
Hi Himanshu. Thanks for commenting. 1 - Yes, all VNDs work this way, regardless of brand. You're basically cross-polarizing in order to reduce the amount of light. 2 - similar to Q1, the full polarization effect is going to be evident at 5 stops, but again, it's two polarizers. The reflection reduction will also vary based on the angle of attack of the light in relation to the shiny surface itself. It's a good point about the 'effect' reducing though. That had me scratching my head a bit. Certainly the 'blue corner' effect is stronger as you shift to a stronger ND.
Sharpness is excellent throughout. I'm sure that if I were to put it through a spectrometer I might get some change to acuity, but visually I couldn't see any difference. Of course, it is another air/glass interface and that means any dirt or sea spray is more likely to have an effect on the image. As long as you keep the glass clean it should be fine. My personal recomendation remains though: if you are looking for absolute IQ and are shooting stills, you'll have more success with a filter system and square filters. If you are doing run and gun work, and in particular shooting a mix of stills and video, then the VND is awesome. I did a documentary shoot for a client two weeks ago and had one camera rig to shoot stills and video while two other cameras shot time-lapses. The 1-5 VND stayed on the stills/camera rig permanently, allowing me to switch between stills and video seamlessly (well...a twist of the ring to get the exposure down to 1/60 for video)
This filter is a very strong polariser. I don't know about other VNDs. I just use fixed ND filters now. I feel scammed, no reviewer except this guy even mentioned it. Grifter filter.
Nisi does make two types of step up ring, aluminium and brass (replacing the titanium ones that were previously the premium step-up ring). Brass are the best to use as they are less prone to jamming and heat/cold shrinkage/expansion that can sometimes happen to aluminium.
Hi Shawn, the short answer is I wouldn't. I'm sure it is possible if you are really creative about putting the two together. If you are needing a VND and graduated filters, you are probably shooting high-end video in which case your most likely solution is a matt box with a 4x5.65" Variable Neutral Density filter (specifically designed for use in a matt box system).
Based on the angle to the sun, yes...although I use it a lot on a 16-35mm lens when I am shooting documentary video work. Not so great for landscape stills, but awesome for reportage video.
Can we use IR cut filter in front of this filter ? because it's rotational which means if attach IR filter that also will rotate and does that effect the image quality have you tested ?
Hi Arun. It's possible, but only with difficulty, and by fiddling a solution. The Vario-ND is really designed to be a standalone filter. But, yes, you can technically mount either an additional circular IR ND filter, although I suggest putting that between the Vario-ND and the lens. I haven't tested it personally, but I would make the educated guess that the IQ shouldn't be affected to badly (although any glass/air interface will affect micro contrast) since it's hte same as stacking filters in a square filter system.
@@emilvonmaltitz So much confusion ... Usually every company says IR pollution cut filter should come last in front of other filters cause filtering function starts from that point for example if you are using a diffusion glimmerglass and ND the filteration order wil be like this : Lens + diffuse it + correct it + cut it , but the confusion is when ur using a VND how to attach the IR in front of it ,? I wish if someone do a proper test by rotating and make sure the motion image will be the same ..
I've just heard there's a new solution being announced by Nisi very shortly which will answer your question properly (it looks fantastic). No fiddling, and you'll be able to add the IR Cut filter in the correct order! It's coming and is the answer for RED and BMPCC users.
Hi Petru. the information that I have found doesn't indicate that it is...but I suspect it might be IR blocking as it doesn't have the magenta caste that is synonymous with non-IR blocking ND filters. Certainly Nisi don't advertise that it is an IRND filter. All of their current square filters are IRND glass (including the Explorer Range) are though, so it would be odd if this isn't.
@@petrub27 which Amazon reviews? If it works for you, why send it back? If it doesn’t work (which only you can gauge for your particular usage) then send it back. If you already have it, test to see whether there is a problem or not.

Very useful info, thanks.
Absolute pleasure!
very well articulated. Thank you
Thanks Arpit!
Great review.
Thanks Zaid
Nice review ❤️
Thanks!

It’s exactly what I’ve done 😂
Hey mr emil thanks for this video . I wanted to ask when do we need to this nd filter . And does this filter comes with little polarize on it?
Technically it is a polarizer…two actually
Thanks for the informative review, Emil.

2. Does the polarising effect decrease from 1 stop to 5 stops? I noticed on the front of the lens that it was maximum at 1 stop and it got back the reflection at 5 stops.
Also, how was the overall sharpness in the pictures / videos?
Did you notice any loss there?

Do you have step up rings? Which ones work with the nisi true colour
Nisi does make two types of step up ring, aluminium and brass (replacing the titanium ones that were previously the premium step-up ring). Brass are the best to use as they are less prone to jamming and heat/cold shrinkage/expansion that can sometimes happen to aluminium.
How would one use this with the Nisi Switch?
Hi Shawn, the short answer is I wouldn't. I'm sure it is possible if you are really creative about putting the two together. If you are needing a VND and graduated filters, you are probably shooting high-end video in which case your most likely solution is a matt box with a 4x5.65" Variable Neutral Density filter (specifically designed for use in a matt box system).
Shame you still can't use it on wide lenses
Based on the angle to the sun, yes...although I use it a lot on a 16-35mm lens when I am shooting documentary video work. Not so great for landscape stills, but awesome for reportage video.
