If you want to slow shutter speed down this works. Still playing around with what else it will do. Took pictures of the total eclipe, but from the West Coast.

Un filtro de excelente calidad, hidrófugo, y de una excelente marca, muy necesario para fotografía y video. Lo recomiendo.

Great ND filter, very good quality and perfect results. I needed a filter to record under noon time light, and decided to give this filter a try, no regrets!

I’ve mainly been using this ND filter on my Rokinon 16mm T/2.2 cine lens and it works like a charm. No weird color shifting or distortion to my images. Easily screws on/off, smooth rotating ring. No hard stops, but that’s to be expected from a budget friendly filter. Overall I’ve grown to love K&F products and this ND works great & has more than enough stops to help me achieve the proper exposure

This filter is very made of aluminum, slim and very light. Very well constructed. Because this filter is 52mm , but designed to fit a 50mm size lens, you will not be able to : 1. attach your lens cap (maybe a 52mm lens cap would fit) 2. attach your lens hood 3. attach any other filters to this one. You are able to attach 50mm filters to your lens, and then stack THIS one onto those filters. I did this with my CPL filter, but found it difficult because I had to rotate the CPL , and then rotate the Variable ND filter, so I removed the CPL for now. Also, I need to investigate whether it is even advisable to use a CPL and ND together because of the low-light. It is really a nice feature of this filter to incorporate 1 to 11 stops on this one variable filter. It makes it easy to dial to the stop that you want to use, but I found it a little confusing. The stops are labeled with Min on one end, Max on the other , and 8 dots in between. So I'm not really sure what dot corresponds to what ND stop, there are supposed to be 11 stops, but there are only 10 markings. Also , there is no lock at the beginning or end of the 10 stop markings. Anyway , I've been experimenting and getting to learn how to use it. I see how it it very convenient to have only ONE Variable filter, instead of several. Much less exptensive, much less complicated. But it is going to take me a little bit of time to learn how to use it efficiently.

The 49mm ND filter came in a typical filter case along with three pieces of microfiber cloth. The filter looks well made. Clear markings on the filter and so easy to rotate and set it to the desired setting. It is easy to mount the filter onto the lens and remove it. The lens cap fits over the filter just fine. I shot quite a few images, the light gathered by the lens is reduced as the filter ring is rotated to a higher stop. Happy with the results for occasional use. I can use this filter for long exposure to get say motion blur. My initial review with some shots of the trees showing the light reduction got rejected and so not including them this time.

I'm a full time filmmaker and I do use several K&D products. I own ND2-ND400 which is from 1 to 9 stops and I love it. Is it the absolute best ND filter out there? No, but cost benefit is unbeatable. So when the ND2-2000 1 to 11 stops was released I got interested. I never actually sat down to do a camera test with my existing ND filter. Images always looked good to me, and I was fine with that. How the test was conducted - I used my Sony A7IV mounted on a tripod with a Cine Rokinon DXS 50mm at f 5.6 which is super sharp at 5.6. I set shutter to 1/80 and used a remote shutter to avoid any vibration in the image. ISO was set to auto. I wanted to see how much ISO variation would happen as I increased the ND dial. Now thinking I should have used an automatic lens and set Aperture priority to see how many F stops the ND would actually trigger but only my cine lenses are 77mm and I don't have a step down ring yet. So, that said: PROS - The filter maintains sharpness and color accuracy throughout it's full ND range, which is amazing. CONS - It gives the image a slightly more red tone. Honestly for skin tones as you can see on the images attached to this review, I actually liked it better, but it does add a bit of color to the image, as expected, especially in this price range. I also noticed that the first 4 stops did not seam to make much of a difference. The camera ISO remain at 800 from stop 1 to 3, and it goes SUPER dark from stop 10 to 11, really, really dark. I want to take a picture of the sun with this ND filter to test it out. Overall for the price it is more than a no brainer. If you are shooting a cinema grade film with an ARRI and some $20,000 cinema lenses, no, not for you. But obviously you can afford the high end ND filters. For social media and smaller budget productions, this filter is PERFECT. Great buy!

upgraded to this K&F VND2-2000 from my K&F VND2-400. This gives me more versatility when I need to get that light stopped down. Weather I'm shooting waterfalls and need long exposure or I'm shooting slow motion and need to stop the light down to keep my shutter consistent, the extra ND is perfect. I'm a fan of K&F their filters are very affordable and the image quality is still quite clear. The build quality and tolerances are quite nice.

My first foray into filters and I'm excited to use this beyond testing indoors and out in direct daylight. The filter comes in a plastic case, which I appreciate. The lens fits great on my Nikon and I love how it's a variable filter, so you're able to shift the lens to create a more dense filter effect along with a wide range of stops. Pretty happy overall and I'm pretty sure this will be a main driver during the summer.

I’ve never used a variable ND filter, so this was really cool to be able to test out. It came in a protective plastic hard case along with three microfiber cleaning cloths. While slightly heavier than normal nano filters, I still was surprised at how lightweight it was comparatively. Adjusting the strength of the ND was smooth as butter. The ring glides with minimal effort to achieve a lighter or darker filter between the min and max settings. If you keep twisting it past these points, it goes through the same grading scale until it reaches the starting point again. The threading is well made, so installing it on my lens was easy. After some testing, I haven’t seen any vignetting or loss in sharpness. There is only minimal color shifting, and I didn’t notice any until around the ND1000 mark. The image quality is fantastic with this, but the really beauty of it is the convenience. While it doesn’t take a long time to change a filter, it becomes annoying quick having to switch multiple times. It also takes up precious space in your kit when you are trying to travel light. With this, there is no more fumbling with multiple filters trying to get the right combo for the shot. If I need to adjust, I just give the ring a quick twist and I’m good to go. And instead of a case with multiple filters taking up space, I have one filter that does the job of a whole set. It’s absolutely fantastic. Nice job K&F!
