Brother, this video actually just saved me $30. I called and immediately switched my order to the ND without the CPL. Thank you, and have a fruitful journey.
Thank you, you've clarified this issue for me now also, I just ordered the Variable ND version.
A wonderfully clear explanation of the difference.
Looks like the version with the cpl would be a real pain when running and gunning.
This was very helpful. Thank you.
You have a new subscriber.
So great to get a review by a cinematographer, and not just someone who shoots video. Thank you.
Clicking your Amazon link so hopefully you get a little kickback.Thanks Eric.
Hi, Buck! Thank you very much! Lately my amazon links have slowed a lot. I think it's due to the economy so I really do appreciate it! I've been very happy with the filter as its not as clumsy as some of the other one's I have used that didn't have the stop points. Thanks, again!
Man...I watched a tons of vnd filters videos and only you did really good real life review. I was really lost but know I'll give a try for k&f. Great video, Thank you a lot!!
Thank you! I am very pleased with the non-CPL version and I am still using it every time I film outdoors. Been also able to shoot waterfalls with it and it helps me hold the shutter open longer! I think you'll be pleased. 😊
I was so confused about the two. Thanks a lot for this video
Wow, such an awesome comparison. Thank you for saving me money. I'm going for the variable ND only over the ND+CPL version.
Meedo Taha thanks! It’s decent inexpensive variable ND. I replaced the CPL one with another ND only one that fits my 10-18 mm lens and it’s working well, too.
I just bought a ND variable only because your recommendation, thank you so much!
Great review I picked up the K&f concept filter only. But now I will have to buy thoes amazing great green sunglasses for the summer 😍👍
This assessment is very practical, unlike other assessments that open a box and then a bunch of nonsense. I am looking forward to your evaluation of N8-128.
Great video! Well explained and tested! Subscribed.
Damn! That was a rad video! Thank you for the in depth info and making it so easy to digest. Subscribed!
Thanks man! I recently got the 67mm version of the same ND2-32 that fits my Canon 10-18mm. Now I'm just waiting for some sunny days where I can test it out as well!
Great review! I'm hoping to pick up one of the combo filters soon! Subscribed! 👍
im very happy and useful to watch this comparing video, I'm going for the variable ND only over the ND+CPL version. cheeers from Amsterdam
so from what i've found online, cpl generally has vignetting for ultra wide focal lengths. so it shouldn't be a problem for 24mm and up.
a comment worth a thousand dollars, thank you!
Wide primes shouldn’t be a problem, just zooms.
Thanks man this is really helpful 🙏🏼
Su frigging preb video and just what I was after! I'll be buying the non CPL version right now! just the review I needed, looks gorgeous with that on. You deserve more subs too bro! subbed.
I like your effort, keep going, you did all the necessary break down
Thanks, will do!
Thank you for this video, you save me away from w/ CPL.

Great video! Thank you for this!
Amazing review man!!! Really clear. Will purchase the variable nd without the cpl.
Louie_vlsc16 thanks for the awesome feedback! I very much appreciate it! 😊
Great video, really well tested and compared.
Thank you so much for this vid!
Great video and clear explanation!
Thank you!
Thanks for this comparison! Im right before to order one and my choice at first was the variable ND Filter with CPL but the vignetting is horrible. The other filter is way much better.
great review... im using both filters... i got away with the vignette by using a larger 77mm on my 52mm WA 24mm lens :)
Thank you very much, very honest 👊🏼🎥
Hello @Eric Cosner. Thanks so much for explaining all this! I have a doubt now. I have 2 lenses....Sigma 16mm (67mm diameter) and Sony 50mm OSS (49mm diameter). I am planning to buy the Sony 18-105 lens (72mm diameter) in future. So, I should get a ND Filter that's of size > 72mm right ? And then use the step up rings to fit the filter on the other lenses ? [Someone else can help as well by replying to this 🙂 ]
Hey yes you should always go for the biggest thread size you have and use step up rings for the smaller lens thread sizes 😁
Dude, great video. You weren't lazy, but actually got out in the snow and gave us some entertaining video. Thank you.
I was about to go through a major hassle to return my promaster variable nd for the K&F one as I also heard there is no X or vignetting. You video clearly proved it's got the same problem as any other variable nd
Very good points! I'm Definitely NOT getting the CPL version because it sticks out too much and I need to rapidly adjust the ND!
Very helpful, thank you.
Great video. Thank you.
Thank you man

Good video. Saved me from getting the cpl version and having those issues
Great review, as I suspected the variable nd is the way to go.
nice test!!
Great video buddy. Thanks for showing us the comparison between with CPL and without. It did seem a bit less when the CPL was turned and the black vignetting moved to the top and bottom.
To me, it seems as if the ND with CPL is focused towards photographers who have the time to set everything up perfectly (I.e. Landscape) and the ND without CPL is focused towards videographers.
Great point! Having the CPL definitely takes more time to get set up right.. and I think you could get weird results with CPL when shooting video, especially when moving the camera around. Plus, I think there's just too much polarizing going on for ultra-wide angle, but yeah that wouldn't matter with landscape where the subject isn't moving around.
I was just watching this well for obvious reasons and stop the video at 11:40 to buy the ND and not the ND and polarized as I was going to do. Thanks 🙏🏼
9:12 that is ideal filter combination for a horror movie. I wish I have had seen this before buying it.
that's just what i thought
Good review
Holy Moses, 82mm? Coming from M4-3 that’s monstrous.
Great demo. Gotta have 2 different filters
I agree with you to a point, but what if you need a polarizer too? If you add a separate polarizer, will it cause that vignetting?
Thanks Bro👍
💯➕Awesome Informative Video FAM
Does the ND+CPL filter have a thread in it? I have a lens hood that screws in and am wondering if I can screw that into this.
Thanks very informative. What mic are you using?
I have a question. When you put the nd filter on, without the cpl, where you able to put your lens hood on the camera?
The ND+CPL sounds like a great idea HOWEVER sometimes in low light you want the ND clean off because even at its lowest setting it's an ND2 which is 2 stops of light. So if you need CPL without ND you still need a 'separate' CPL. 🤦♀️
ND2 is one stop of light
CPL in low light?
i need suggation..
if i am using 2 in 1 filter then for sure vigneting will come right but in 2 in 1 filter using only ND then it wont right?
it will come on 16mm lens only and if your using two lenses together
How do you open the cpl filter... for cleaning?
Hi Eric. Thanks for this. It’s clear for me that am gonna go for the VND filter without CPL. A lil question: What would you choose? This K & F concept Variable ND 2-32 or the K&F Concept Variable ND 8-2000???? and why. Thanks :)
Hello @BackpackeRom! In my opinion, the ND 2-32 range will be fine for most circumstances and lenses. The latter ND 8-2000 would filter out light even more. It could depend on what you are filming or photographing and the speed of your lens. If you have a very fast lens like an f/1.2 and you were using it for cinematic shots on a bright sunny day, then perhaps the ND 8-2000 would be better, but I really haven't tested it. The lens I used in this video was an f/2.8 and the ND2-32 seemed to work well. When it gets later in the evening, ND2 is going to be better because it's almost like having no filter at all, where the ND8 setting would be more noticeable. Hopefully that helps! If you have other questions, let me know. 😊
All var ND filter have 1 linear and 1 circular polar filters. The difference is that mostly you cannot turn the whole filter itself.
I think there is a newer model. It has orange tabs.
Maybe the CPL is on th outside.
I feel this would solve the problem ofnone hand use
Is it just me or is the front glass of the nd cpl combo off center?
Nice
I still got the filter personally.
Even though I can see how this has really bad vignetting, BUT its only when you max out the ND which I would never do. Your camera even had to compensate all the way up to 5000ISO and you're in really bright snow haha! Mind you, I am a videographer. I can see how this could be bad for photographers.
Hi. I have 11mm wide angle lens with 77mm thread and can see vignetting. Do you think getting 82mm and step up ring eliminates the vignetting at 11mm?
@@bizjakboris it’s hard to say without actually trying, I personally don’t have a lens that wide.
@@itsPandaPoops thanks for replying.
Hey Buddy!! Hope you doing well. I just wanted to know that Can we use a lens cap with the filter on?
Yes, but you may have to get a slightly larger lens cap that fits the ND filter. There are female threads on the front of the K&F concept filters but they are usually in size than the threads that attach to the lens.
I really want to get the nd+pol 82mm filter, but I want somebody that has it to confirm if a 82mm lens cap works on it or do I need 85mm cap (hard to find, but necessary for protection)
You will need the 85 lens cap
Nice video! I mostly shoot travel videos with sony 18-105mm F4. I think I will be getting the K&F 2-5 stops and polarpro 6-9 stops. Do you think these 2 would be good? I don't really want to buy 2x polarpro (2-5 and 6-9).
I've been happy with my K&H 82mm 2-5 stops variable ND that was in the review. I recently bought a second one at 67mm and it's doing great as well. I honestly can't really complain about them for what I use them for. You might also want to check out Moment Variable-ND filters that recently came out. It seems like they are priced somewhere in between the K&H Concept and PolarPro.
Been looking all week for a photographer video on these filters. Too many recorders are showing off this photography lense for recording 😢
What types of use cases are you interested in for photography?
Looks good. K&F gives value for the money that other very overpriced filters don't.
Rolf Berge thanks! I totally agree. The fact that they have built in stops at min and max is great. I have one for my full frame camera and one for my cropped 80d. Both have minimal vignetting at wide angle.
Is it possible to sqrew a rubber hood on the nd+cpl filter?
I'm actually not sure because of how the adjustment knob sticks out. I think it might work for the one without the CPL, however mileage may very due to the type and size of the rubber hood.
So do you recomend using both a variable ND and a CPL instead of the combo?
This is what I wanna know too
How i could achieve that?
After having seen your vid, I decided to go for the K&F ND2-ND32 (non-CPL). I tested it also with the Canon EF16-35 2.8, but the vignette is much worse here, more or less like with your CPL version. The vignette is about 3EV, when trying to compensate on a photo in LR.
Optically it is 100% identically to the cheap K&F ND2-ND400, but with mechanical limits to avoid the X.
Thanks for the comment! I wonder if there are variances in production. The only time I really notice vignetting with my 16-35mm 2.8 and the non-CPL version are on days with clear sky. These days I notice a slight darkening in the sky and it's more noticeable when I'm panning on handheld.
@@EricCosner This would be absolutely okay for me too. I'll see what the support tells me ;) Thanks for your answer and your nice review!
Interesting demonstration. I was hoping to buy the VND+CPL filter but now I won't. Will it be possible to screw on a standalone CPL filter to the ND2-32 filter?
You can screw another filter onto the front of the VND, but I'm not sure if it would cause the same issue. From what I understand, the VND actually uses two CPL filters to reduce the light. I think that having VND+CPL is just too much light polarization for an ultra-wide angle lens. I have read other comments where they say the VND+CPL worked for them, but usually they aren't on a wide angle lens.
@@EricCosner I also thought that by having two standalone filters it might solve the problem with needing two hands to turn the filter but I guess if they are screwed on tight together, they will both turn if you don't hold one down with the other hand.
@@stanleystevens6278 I think you are right, one would turn the other one regardless of which one was placed first. That was the awkward part about the VND+CPL version. It seemed like it could work if you had time to get things setup a calibrated, but if you are in a hurry then it got annoying quickly.
will the lens cap fit on the nd Variable?
is the polarizer important? or is it enough to buy only nd?
You will likely have to find a larger lens cap. I find the female threads on the front of the VND are larger than the male threads that connect to the lens. I think the polarizer can be important if you shoot over water, but it just seems very cumbersome for video. I think it makes sense to get them separate if you want both, especially if your lens is an ultrawide. Most people who have commented have the vignetting issue with the ND+CPL all in one.
I didn’t get any “X” I have the 105mm too
Whats the best ND filter strength for shooting in daylight at around F1.4 and keeping 1/50 shutter @ 24fps? cheers. I'm finding nd32 is not early enough blockage to achieve the settings above
You may want to have a look at the same filter K&F ND8-ND128. I haven't personally tested it, however at f/1.4 you would most likely need a darker filter 😊
@@EricCosner exactly. I have the KnF ND8-2000 arriving sunday, testing to follow
Open Connection awesome! Let me know how it goes!
@@openconnection how did it go?
I was trying to find something about these filters.. They actually make them for drones which is what I got... And I am experiencing the same vignetting. Disappointing.
Thanks for the review Eric. I'm tossing up between the K&F v Nd and the Nisi nd-vario pro nano 1.5-5 stops for my Sigma 16mm f1.4 on my Sony A6400. At $A65 vs $A200, the K&F looks like good value.
Do you reckon 5 stops is enough for 1/50s, about f2.8, 100 iso in bright Australian sunlight?
Hi Troy! Thanks for the comment! For my Canon camera the 5 stops is definitely enough for me at 1/50th, f2.8 100 iso, but I know the A6400 is much more sensitive to light than my camera. Before buying the filter you could reduce your aperture by 5 stops and that should be the same (but with less bokeh). I used a website and it looks like to reduce from f/2.8 by 5 stops it comes out to f/15. If you want to reduce f/1.4 by 5 stops, set it to about f/7. In my testing I found the K&H stops to be very accurate. Here's a link to the f-stop calculator: imaginatorium.org/stuff/stops.htm
@@EricCosner Cool, thanks Eric!
@@EricCosner The calculator says about 6-7 stops is required based on my settings I used for bright sunlight video. So I'm going to get the ND8-ND128 version of this filter. Thanks again!
Troy Jones awesome. Would be curious to hear how it works! You could always get the other one later if you find you need one for different lighting.
does this ND filter have green color cast?
I don't think it produces a green cast. Here are two videos shot using the filter. The tent video was in the summer and the other in the winter. It was very lush and green in the tent video so it may be hard to tell.

I think there is something wrong with you nd2-32 variable filter. Cause i have the same but not vignetting. Works good
What lens are you using it with?
Where is this world and it's so cold and snow?? haha, I have the Variable ND from K&F,the old one,works great but i bought the Neewer version of this ND and CPL . Probably the same filters?
We're in the Appalachian mountains.. it was actually just snowing two days ago haha. I figure they could be similar. As I mentioned at the end my last filter was a Zomei. It seemed like the quality of glass was about the same, but K&F did better with the built-in hard stops. I have a Neewer for my iPhone. Moment makes a similar one, too. I'd like to get my hands on it and test it.
Good stuff. Finally affordable good ND+CPL filters
Hello, Can we use this k&f concept variable nd filter (nd2 - nd32) and lens hood together on the lens? Thanks
Karn Gaur I think most lens hoods would probably allow for it, but I can’t be 100% sure. I have a 67mm and a 82mm. Unfortunately I don’t have a matching lens hood for either lens. Here is a photo showing them attached and you can see the lens hood threads behind the ND filters. Hope this helps. twitter.com/geekinit/status/1294275293125971971?s=21
Karn Gaur I was able to use a step up ring and get one on a Nikon lens. It’s a little more cumbersome to adjust the ND with the lens hood on but it did work in this particular case. twitter.com/geekinit/status/1294277097863741440?s=21

@@karan111987 thank you very much! Stay safe! Wishing you all the best! 😊
trying it without the iso on iso could help us better
Hey thanks for the feedback. I did another review a bit later on the same ND filter which might be helpful to you. For some reason that one doesn't get the views 😂 but I manually set the iso on that one. Here's the link: czcams.com/video/f6ZxQiPqdeM/video.html
16-35? How about in 24mm. Its vigenetting?
As long as you don't go with the CPL version I think you'll be happy with the results. You might see some minor vignetting at 16mm if you have a solid color in the background, but at 24mm I think you'd be fine. I sent the CPL back so I can't directly test it at 24mm anymore, but it was okay at 35mm if I remember correctly. Some people think I got a defective ND+CPL filter, but when I ask them what focal length they were shooting at, they never reply 😄
Im confused which one is the last one ? Both have similar reviews
The one I preferred is the one without the CPL. I updated the description to hopefully help. It may depend on your use case. I find the VND+CPL gets returned more to Amazon than the one with only VND.
@@EricCosner great thank you.
would you explain why you get (ND 2 to ND32) instead of (ND 2 to ND400) ?
나누기tv - Share tv *검은수염 Blackbeard* hello, the K&F Concept ND2 to ND400 is new, they didn’t have it when I did this review. I actually had a ND2 to ND400, however it was made by Zomei and didn’t stop turning at the min and max, and then I discovered that ND32 was actually dark enough for video 😄
@@EricCosner thank you soooooo muuuuuuch for very quick reply :D so which one is your recommendation for video? plz, give me advice! cheers 👍
나누기tv - Share tv *검은수염 Blackbeard* it may depend on your camera and lens. Since the ND2-N32 goes from 1 to 5 stops, each time you double your shutter speed, it’s 1 stop. So if you shoot at say 1/50 shutter, lens aperture wide open and iso at 100, then you speed the shutter to 1/1600th of a second, then that would simulate 5 stops and then see how the camera performs on a bright sunny day. Just one way of doing it. 1/1600th shutter isn’t good for video but would simulate the exposure. I will say sometimes V-ND filters that go out to 400 or even 500 begin to show color cast and vignetting especially on ultrawide lenses, but also some cameras that perform really well in low light, ND32 might not be dark enough.
@@EricCosner really really appreciate it!!
you the best!!!!!!!!!!!!!!!!!!!!!!!!!!! i will go with nd 2-nd32 :D thx for teaching!
나누기tv - Share tv *검은수염 Blackbeard* no problem! Another way to possibly look at it, if your camera does really well at night (low-light), then you might consider the ND2-400 during the day. I’m going to get one to review and compare! Thanks for giving me the heads up!! I didn’t know they had released a new one 😄
The concept is not that bad. Use it with one hand all the time
Sunglasses are so cool ngl
Why are you waring reflector glasses
Thank you for asking. They help with framing and allow me to adjust my camera settings in real time. And it allows my viewer to see what I’m seeing. But above all, my eyes are sensitive to bright light. They are basically just ND filters for my eyes.
I wouldn't be surprised if he's like Casey Neistat - he admitted that he wears sunglasses in his videos partially so people don't see his eyes wandering to the screen. Makes sense if you're vlogging IMO.
I really think that possibly you have a bad one. I just recieved mine and even at the darkest im not seeing even a little vignetting
I've been wondering about this for some time. I'm curious how wide is your lens (mm) and did you get the ND+CPL version? Thanks!
I just purchased one as well. Great video but I hope it was a bad one.
@@MogulGroup1985 let us know when it arrives. The issue with the CPL really only occurred at very wide angles. Hoping it works for you 🤞
If you use only the polarizer or ND setting, does it still vignette
In my tests the only way to reduce the vignetting was to keep the ND setting low. The CPL polarizer is always polarizing the light, but just at different angles as it's rotated. It seemed like the vignetting wasn't bad at 35mm.
Eric Cosner think there would be any problems on a 10-18 wide angle with only the ND set, no polarizer
@@kpritch2387 I actually have that one!! My other camera is an 80D and I use the 10-18mm with the 67mm VND K&F filter. I shot this vlog with it. czcams.com/video/7OWRb14n5es/video.html . You'll notice some darkening in the sky at times. I thought it turned out okay considering it was full sun that day. I believe I kept the filter around ND4-8.
Eric Cosner awesome I’ll check it out. Thx for the info!
@@kpritch2387 No problem. I started reviewing the 67mm one, but still haven't finished the video lol. Thanks for stopping by!
German or Japanese glass?
I wish I knew. I can't seem to find any documentation. Overall I'm impressed with the K&F Concept Variable ND2-32 without the CPL. I bought a second one for my 10-18mm and both are holding up great.
@@EricCosner hi thanks for replying, my comment may of seemed short but it was 4am and I was trying to decide on which filter to order. The real answer of course is my eye probably won't know the difference!
@@ianwhite4315, understandable! NDs are tricky science. I think I want to do another review. So many things to consider and I've learned so much. Thanks for the reply! 😄
I'll assume, that If it were made in germany, it would be quite a bit pricier..
don't use VND on wide angle lens.................
In case you are wondering how I do VND on ultra wide these days here is my video where I’m using in-line VND filter 😄 czcams.com/video/DPL8De8raJA/video.html
Why are you wearing glasses inside your house
It helps me check framing and run the camera. I’ve kind of got away from it recently.
@@EricCosner check framing how? and exactly how does it help with running the camera? genuinely curious.
@@mzzah06 when I wear sunglasses it frees my eyes up to look at camera settings, my laptop and to check the camera’s flip screen to see if everything is in frame, without looking like I’m doing those things. These days, when I’m indoors, I just look into the black void of the lens without wearing sunglasses. My eyes are sensitive to light so I always wear them outdoors. In the early days I tended to look up at the ceiling a lot when I was talking 😂
Thank you, decided not to buy anything.
Should I get 6-9 or this🫡
